Cereal grasses, such as wheat grass and barley grass, are the young green plants that grow to produce cereal grain. Cereal grasses are often called "green foods" along with spirulina and chlorella.

Food Sources

Wheatgrass is the young grass of the wheat plant, Triticum aestivum. It grows in temperate regions throughout Europe and the United States and can live indoors or outdoors. Many people grow their own wheatgrass by putting wheat seeds in water and then harvesting the leaves.

Wheatgrass is a natural source of vitamins and antioxidants, including:

Vitamins: A, E, and B-12
Minerals: Calcium, Selenium, Magnesium, Iron

One ounce of wheatgrass juice is equivalent to the vitamin and mineral content of one ounce of fresh vegetables.

Uses

There are many potential uses for wheat grass. Since wheat grass contains chlorophyll, there is reason to believe that wheat grass exerts some of the same benefit as chlorophyll such as anticarcinogenic action.[1].

Some potential uses for wheat/barley grass include: [1]

The only recommended dosage that has been established is for adults at 3.5 grams daily. To determine what your specific requirements are talk to your naturopathic doctor or other trained medical professional.

  • Wheat grass and barley grass supplements are available as powder, in tablets, and as juice. They can also be found in combination with other "green-foods" such as spirulina and chlorella.

Safety

Barley grass and wheat grass are generally regarded as safe. The safety concerns noted include:

  • Pregnancy and Breastfeeding
  • Wheat grass and barley grass should be avoided during pregnancy and breastfeeding.
  • hypersensitivity to components of wheat grass or barley grass may occur.
  • Warfarin - Wheat grass and barley grass may contain high amounts of vitamin K and therefore should be used with caution in those on warfarin therapy. Monitor INR.

Thinopyrum intermedium

Species of flowering plant

Thinopyrum intermedium, known commonly as intermediate wheatgrass,[1] is a sod-forming perennialgrass in the Triticeae tribe of Pooideae native to Europe and Western Asia.[2] It is part of a group of plants commonly called wheatgrasses because of the similarity of their seed heads or ears to common wheat. However, wheatgrasses generally are perennial, while wheat is an annual. It has gained the Royal Horticultural Society's Award of Garden Merit.[3]

Trials with intermediate wheatgrass, the product of which is trademarked by the Land Institute as "Kernza", show that it can be grown as a “multi-functional” crop, yielding various commodities as well as ecosystem services. Whereas annuals such as corn tend to deplete soil organic matter and require inputs, a perennial grain such as intermediate wheatgrass can yield crops while building soil organic matter.[4][5]

Synonyms[edit]

Scientific names[edit]

Many scientific binomial names have been given to the species Thinopyrum intermedium. Multiple species or subspecies have been described based on different morphologies, like the presence or absence of pubescence. Here is a partial list of the binomial synonyms for Thinopyrum intermedium:[6]

Agropyron aucheri
Agropyron ciliatiflorum
Agropyron gentryi
Agropyron glaucum
Agropyron intermedium
Agropyron podperae
Agropyron pulcherrimum
Agropyron trichophorum
Elymus hispidus
Elytrigia intermedia

Common names[edit]

Intermediate wheatgrass is the most widely used common name for Thinopyrum intermedium in the United States. The name "intermediate" probably refers to the height of the plant, which is generally somewhat shorter than Thinopyrum ponticum known by the common name of "tall wheatgrass."[citation needed]

Wild triga is the common name that was given to Thinopyrum intermedium by researchers at The Rodale Institute. The name was intended to distinguish varieties of the species developed for use as a perennial grain crop from foragecultivars which are identified by the common name "intermediate wheatgrass".[7]

Kernza is a trademarked name held by the Land Institute for the processed grains of intermediate wheatgrass.[5]

Origin and distribution[edit]

The native range of intermediate wheatgrass extends from central and southeastern Europe to Asia Minor. Although it was first brought to the United States in 1907, the first successful introduction was from the Caucasus region in 1932.[8] The plant can now be found growing wild throughout the Western United States and Western Canada.[6][9]

Thinopyrum intermedium is best adapted to:[6][failed verification]

  • Regions with annual rainfall between 12 and 30 inches (30 and 76 cm)
  • Soil with a pH between 5.6 and 8.4
  • Locations with full exposure to the sun
  • A wide range of soils but with a minimum depth of 16 inches (41 cm)
  • Locations where the minimum temperature exceeds −38 °F (−39 °C)

Uses[edit]

Forage[edit]

Thinopyrum intermedium is among the most productive forage species for the western United States. Because it heads relatively late, it can be grown effectively in mixture with alfalfa to increase its productivity, longevity, and forage quality. It regrows slowly after grazing or cutting, making it best suited to management with a single harvest per year.[10] If multiple harvests are needed per year, other species will be more productive. If managed well, stands can persist for up to 50 years.[citation needed]

Habitat[edit]

Habitat for wildlife - intermediate wheatgrass can be an excellent food source for grazing and browsing animals. Left unharvested, the vegetation is a good nesting habitat for some birds and waterfowl. Generally, it is not an invasive plant and coexists well with native plant species.[citation needed]

Soil management[edit]

Soil management by way of erosion control and land rehabilitation are additional uses for this plant. It establishes quickly to form a protective mat of roots and rhizomes, even when planted on soils degraded by earth moving or mining. Within five years, stands have produced up to 7,000 pounds per acre (7,800 kg/ha) of the dry root mass in the top 8 inches (20 cm) of soil.[10] Heavy root production holds the soil in place and restores its natural fertility by increasing the soil carbon.[citation needed]

Grain[edit]

Thinopyrum intermedium is a perennial grain crop. In 1983, the Rodale Research Center evaluated close to 100 species of perennial grasses to identify those with good potential for development into perennial grain crops. Intermediate wheatgrass was selected as the most promising species based on flavor, ease of threshing, large seed size, resistance to shattering, lodging resistance, ease of harvest, and perennial growth.[11] Intermediate wheatgrass is nutritionally similar to wheat, and the grain can be ground into flour and used for food products, including muffins, tortillas, pancakes, cookies, crackers, bread, beer and whisky. Some products have been marketed under the trade name Kernza.[12]

Seed production[edit]

Although the primary use of Thinopyrum intermedium is as a forage, seed production is essential because farmers and ranchers continue to establish new stands by planting the seed. In 1988 over 500 metric tons (550 short tons) of seed were harvested in Saskatchewan alone, although more recently the harvest has fallen to less than 225 metric tons (248 short tons) in that Canadian province.[13] Average seed yields are about 330 pounds per acre (370 kg/ha), but on-farm yields of up to 880 pounds per acre (990 kg/ha) have been achieved. Seed is generally produced in rows spaced 30 to 36 inches (76 to 91 cm) apart. The wide row spacing (relative to grain crops like wheat) allows for sustained seed yields for five to ten years. Without spacing and occasional tillage between the rows, yields decline rapidly as the plant population becomes increasingly dense through rhizome spread. Despite this, Thinopyrum intermedium is still considered lesser than wheat by some, as its seeds are comparatively tiny.[14]

Breeding for grain production[edit]

Intermediate wheatgrass, Thinopyrum intermedium, has been widely hybridized with wheat in the effort to transfer traits such as disease resistance or perenniality.[15] Transferring leaf rust and powdery mildew resistance to wheat has been a special interest.[16] But, attempts to directly domesticate the species into a grain crop did not commence until workers at the Rodale Research Center began to evaluate collections in 1983.[17] In 1989, after assessing 300 collections, the workers selected the best twenty based on grain yield and seed quality. The selected collections were allowed to intermate, and 380 progeny were evaluated between 1991 and 1994. The best eleven plants, plus three from another evaluation, had intermated, causing a second cycle to begin. Seeds from the best plants in the second cycle were passed to scientists at The Land Institute, where the research has continued.

In 2001 and 2002, seed from the first and second breeding cycles of the Rodale Research Center was planted at The Land Institute. In the fall of 2003, 1000 individual plants were dug up and vegetatively propagated to obtain three clones of each plant. The 3000 resulting plants were randomly transplanted to the field on a three foot by three-foot grid. In this manner, genetic differences between plants were separated from environmental influences. In 2005, heads were harvested from every plant and threshed to remove the seeds. The seeds were both counted and weighed to determine the yield per seed head and weight per seed. The fifty plants with the highest yield and largest seed were selected to intermate in 2004.[citation needed]

In the fall of 2004, 4000 progeny were planted to establish the second cycle of breeding at The Land Institute. In 2008, these plants were harvested separately by using a power scythe and threshed in a combine. Again the best 50 plants were selected, this time based on yield per head, seed size, shortness, and free-threshing ability.

The selection methods described above have increased seed size and yield by about 10 to 18% per cycle.[18] But perhaps of greater importance has been the discovery of two Mendelian traits. The first is dwarfing, which results in stems about 30  cm shorter than wild-type plants and short, erect leaves (see photo). The second is a more subtle change in head shape which results in thick, non-brittle heads and slightly larger seeds (see picture). Both of these traits appear to be controlled by dominant genes.

The whole process mentioned above is called mass selection, which is breeding and selecting the best individuals to spawn the next generation. Mass breeding, however, is a process by which large quantities of genetically diverse individuals are made. Due to Thinopyrum intermedium's grass-like structures, some believe that it still needs to be domesticated as much as possible to resemble wheat.[19]

The fact that Thinopyrum intermedium is a perennial grass is important with regards to its use as a grain. The plant persists and can be harvested year after year, and its domestication would yield an additional three months of agriculture; its leaves are most active in the months in which common wheat is not active: July through September. Despite the promise, the yield per acre of Thinopyrum intermedium is 26% of the yield of traditional wheat. Because of this, some are putting effort into hybridizing wheat and Thinopyrum intermedium instead of attempting to domesticate Thinopyrum intermedium to a more acceptable yield.[20]

Hybridization with wheat[edit]

Attempts to hybridize Thinopyrum intermedium with wheat have also been done. This has some distinct advantages. First, there is wide evidence that hybridization of Thinopyrum intermedium with wheat is a method to confer fungal resistance to domestic wheat plants. However, which specific genes that protect against which specific fungus has not been as well studied. Thinopyum elongatum and Thinopyrum intermedium impart a total of four leaf rust resistance genes, while Thinopyrum intermedium confers two powdery mildew genes.[21] There's evidence that Thinopyrum intermedium also has resistance to wheat streak mosaic virus, the Aceria tosichella mite, Barley yellow dwarf, and others.[22] These conferred genes in wheat help increase yield and hardiness in times of environmental strain. Second, Thinopyrum intermedium also has genes that improve bread making when hybridized common wheat. While this may not seem like an important characteristic, better bread may mean more calories, feeding more people. In addition, bread that stays fresh longer may provide more opportunities for people to be adequately fed, and/or the bread can be transported to areas without much food access.[23]

Strategies for domestication[edit]

The Land Institute has been working to develop viable wheat and Thinopyrum intermedium hybrid since 2001, and there have been several successful strains that shared 14 Thinopyrum intermedium chromosomes and 42 wheat chromosomes. These hybrids perform better regarding yield and resistance than either of their parents, but it cannot be widespread due to the changes of climate across the world. Also, perenniality is lost with these hybrids. This loss of perenniality is a common problem with hybridization attempts. All other desired characteristics are present in the hybrids - large seeds, good yields, etc. - except that the plants have taken on too many wheat characteristics: they are annual. However, crosses between durum wheat and Thinopyrum intermedium have resulted in hybrids that do exhibit perenniality in addition to other desired characteristics (increased vigor, hardiness in colder weather, good yield).[24]

There are three general strategies for domestication of Thinopyrum intermedium with the purpose of creating an alternate grain crop:

1) One strategy is to domesticate Thinopyrum intermedium through mass breeding and selection to create a strain that mimics wheat's seed size and yield but retains Thinopyum intermedium's natural resistances, hardiness, and perenniality. In other words, this strategy gives Thinopyrum intermedium more wheat-like characteristics;

2) A second strategy is to hybridize wheat with Thinopyrum intermedium to create a strain of wheat that mimics Thinopyrum intermedium's resistance and perenniality but retains wheat's seed size and yield. In other words, this second strategy gives wheat more Thinopyrum intermedium-like characteristics. Researchers hope that these two strategies will progress and meet in the middle;[19]

3) A third strategy is to benefit from what we know about the molecular events that led to the domestication of evolutionarily related grasses such as wheat and barley. Mutations in so-called domestication genes in wild ancestors led to the domestication phenotypes that characterize these crops today. If related genes can be identified in Thinopyum intermedium it may be possible to mutate them by new breeding technologies, and in this way accelerate domestication.[25]

Schnabel's statement[edit]

(Hmmmm... a chart is presented, that shows that an ounce of wheatgrass JUICE is roughly equivalent to an ounce of broccoli or spinach (I guess, raw). If the juice is made by adding 1 - 2 ounces of wheatgrass powder to a quart of water... then... that would make wheatgrass (the dehydrated powder) roughly 23 times as nutrient-dense as these "choice vegetables"!) — Preceding unsigned comment added by 96.239.74.52 (talk) 05:39, 24 August 2016 (UTC)[]


"Fifteen pounds of wheatgrass is equivalent to 350 pounds of the choicest vegetables"

He never said such a thing. As a Schnabel biographer, I have read all his research and writings and have never seen any such quote from him. You use as your source for this incorrect statement a book from a proponent of growing wheatgrass unnaturally indoors, which is exactly the opposite growing method used by Schnabel. And in that book, if you take the time to review it, the author never gives any reference whatsoever for this absurd statement attributed to Dr. Schnabel. He obviously just made it up and you reported it as fact. In doing so, you tarnished the reputation of Dr. Schnabel, who never said such a thing. You allowed the use of this statement to make what is clearly straw man argument.

Moreover, to make matters worse, you allowed the author of this lie about Dr. Schnabel to go on to prove has straw man argument using bogus data in a chart that should never have been allowed (as well as the straw man statement itself). The chart regards wheatgrass grown indoors, not Schnabel's wheatgrass. The comparison with broccoli and spinach does not make it clear whether the amount is 350 pounds, one pound or what. It doesn't say whether the vegetable were fresh, dehydrated or anything about it. It is very, very unprofessional to use straw man arguments in the first place, but then to support such nonsense with bogus charts is extremely irresponsible. Whoever wrote that crazy paragraph defamed the reputation of one of the greatest scientists of the 20th Century.

You also allowed another reference from an article, probably from the same very dubious source, to support this statement:

"Proponents of wheatgrass make many claims for its health properties, ranging from promotion of general well-being to cancer prevention. These claims have not been substantiated in the scientific literature.[1]"

This "scientific citation" for the above statement was a poorly written opinion from an obscure blog. In the first place, no company that I have ever heard of has ever made any healing claims whatsoever for Schnabel's form of wheatgrass. People who grow it in their kitchen might make crazy claims, but people who grow herbs in their kitchen also make crazy claims. They make all kinds of crazy statements, but you will never see such statements made by companies that sell wheatgrass grown in the way Dr. Schnabel grew his. To allow such a statement about "claims" being made and implying that they are being made by responsible people is irresponsible. Again, this is a straw man argument. You allowed the author to make an unsupported statement; i.e., that all kinds of claims are being made, and then prove his the straw argument with an opinion by some crackpot on a blog. That is so very wrong.

Before you start looking for more accurate citations, you need to get rid of the ones mentioned above that have that have no basis in science and that are being used to support false statements in a kind of circular straw man argument fashion. Do you really want scientific citations or do you prefer that people to make up nonsense statements and use their blogs as a citation to prove what never was said in the first place? That appears to be the case.

As an indication that you reject scientific citations in favor of citations of opinions from blogs, I point out that I tried to put up a scientific article to this page today and it was rejected. That article was published in the Journal of Biological Chemistry (http://www.jbc.org/content/152/2/215.short). It was rejected as not "being scientific;" Do you know anything about this Journal? It is very respected and has been for nearly 100 years.

http://www.jbc.org/

It certainly has much more credibility than citations from blogs or unsupported quotes from books about growing wheatgrass, especially when their methods of growing are completely inconsistent with what Dr. Schnabel and other noted scientists used in more than 30 years of research actually published in respected scientific and medical journals, not blogs!

As soon as you correct these straw man arguments and the bogus citations and that bogus chart, I will sign up, log in, and try to help you turn this article into something respectable with actual scientific and medical citations from respected journals rather than opinions from blogs and third party quotations from books written by people who don't have a clue about Dr. Schnabel's research. -- — Preceding unsigned comment added by 71.208.251.240 (talk) 02:06, 21 June 2013 (UTC)[]

Let discuss editing the section here. Lord knows it needs editing. Anthon01 01:04, 24 October 2007 (UTC)[]

Sounds good. I agree that the section needs editing, it certainly doesn't flow very well. Deleting sources from it probably isn't the best place to start though. Why do you think the source is biased? It comes from a not-for-profit consumer organisation. Pacey 22:19, 24 October 2007 (UTC)[]

If the sources are not balanced or authoritative then yes. The sites contains statements like "Don’t believe all you hear or read — very little good-quality evidence exists to support the extravagant claims made for the benefits of wheatgrass juice" and "If you believe the hype..." The fact is aspirin was used for 80 plus years before anyone figured out how it worked (1983). There a whole lot of medicine still being practice today that is nothing more then anecdotal. The references on the site are very limited.

IMO, the hyperbole makes the site seem bias. I think we can find a reference for Schnabel's quote minus the rhetoric. The site also isn't authoritative. Frankly, it is difficult to find good balanced references on the internet since most of the wheatgrass sites are selling wheatgrass. You can also find a USDA reference for nutrition data. That's a authoritative reference.

Regarding his statement: Schnabel worked with wheatgrass powder; his goal was to make it avaiable year round. He produced a tablet, Cerophyll, that was accepted as a food by the AMA. I suspect that his statement was correct, if you consider that the only way his statement makes sense is if he was comparing his dehydrated wheatgrass (Cerophyll) tablets to fresh vegetables. Jrrmin49 tried to rewrite Schnabel's statement; without a reference that doesn't fly. But I think his underlying premise is correct.

I am looking for more research then what exist on the internet. I believe it exists. There is also alot more research on barley grass juice and powder. Some studies compare BGJ and WGJ and find the barley a little better. There is also research on Clorophyll. WGJ contains high amounts of it. There are a few other substances found in WG that have been researched. Most of this research supports many of the claims. Anthon01 04:00, 25 October 2007 (UTC)[]

Thanks for your response. With regard to your points:
  • It seems like your problem with balance relates to the tone of the article. Bear in mind that what is available online is only a partial summary of the full article, which isn't available online. I was actually citing from the text version, as the citation indicated. I got a copy from my local library, if you can't get hold of it I may be able to scan it and email it to you or something. The text version was written quite differently. It started with a more neutral intro, discussing, in particular, the anecdotal claims about the benefits of wheatgrass and mentioning the lack of scientific evidence either way. I agree that the tone of the internet article might make it sound like they were biased - I think this is because it's been reversed, the conclusions are presented first in the online source, and they're presented in a way that's meant to seem eye-catching.
  • I agree, it is difficult to find good balanced references on the internet since most of the wheatgrass sites are selling wheatgrass - I expressed this view elsewhere on the talk page. It's also difficult to find authoritative references. That's why I think this source is worth having. It is authoritative and independent: Choice is the largest consumer organisation in Australia, and the public face of the Australian Consumer Association. They're a not-for-profit organisation, and they're independent - they receive no funding from the government or any organisation. They're represented on numerous national and international committees (including the UN Environment Program). They have no vested interest in making a negative finding about wheatgrass; on the contrary, it's in their interest to give the issue unbiased consideration.
  • I did originally have another source for Schnabel's statement, I think. If my memory serves me correctly it was removed because it was a commercial website...
  • I think it's great that you're looking for more research - that's what this article needs.
Back to the first point, I think the source is fine if you read the text version. With that in mind, I think it's reasonable to restore the source without the reference to the internet summary (or perhaps indicating more clearly that it is a summary, and doesn't reflect the full text of the article). Pacey 10:44, 25 October 2007 (UTC)[]

I'm not sure about Australia, but in the US, healthcare entities (medical orgs, peer-review journals, medline, medical professionals) are considered to be authoritative in regards to healthcare; we don't consider consumer magazines or orgs as authoritative. The article's citations are based on very limited review of the literature. Their conclusions are as a result, unbalanced. Who wrote the article? The online version gives no indication of who. I'd like to get a copy of the text article if possible.

A better source for nutrition info is the USDA (US Dept of Agriculture). Would you agree?

You also said nothing about my comment about Schnabel's statement being correct. That would make these comments comparing WGJ to a salad or another vegetable unnecessary. I'd like to reword that section to reflect the fact the Schnabel statement has been interupted to mean wheatgrass juice when in fact it doesn't mention juice. Anthon01 15:33, 25 October 2007 (UTC)[]

In addition, non-profits in the US are commonly set-up to further the interests of for-profit orgs. Anthon01 15:36, 25 October 2007 (UTC)[]

On further review, I'll concede that your reference is independent. I still don't consider them to be a authority on health, and consider their review incomplete and inadequate. Anthon01 16:24, 25 October 2007 (UTC)[]

Addressing each of those points:
  • I would say that a consumer organisation is authoritative with regard to nutritional information - one of the key roles of these organisations is to provide independent nutritional advice. The source in question is only cited in reference to nutritional info. Although the Choice article deals with health claims, these are not cited here.
  • I'll have to check who wrote the article at a later date, I don't have it to hand. I've put it on hold, I'll let you know when I get it (I'll scan it in at that time too).
  • I have no objection to citations from the USDA. I tried searching the USDA National Nutrient Database for wheatgrass, but I got no results.
  • Even if your interpretation is of Schnabel's statement is correct, that does not make the comparison of wheatgrass to other vegetables unnecessary. The key sentence is the first sentence of that paragraph - retailers and supporters of wheatgrass use frequently claim that a shot of wheatgrass is as nutritionally valuable as a kilo of vegetables. The nutritional info on spinach and broccoli is included to disprove that point. The reason for including the statement attributed to Schnabel in that context is to illustrate where the former claim is thought to originate from. This is a section on health claims, not on Schnabel's statement - the inclusion of Schnabel's statement is incidental. I'm restoring the nutritional info on that basis, I'm also rephrasing the section so as to avoid the confusion with regard to Schnabel's statement. I think it reads better with Schnabel's statement in the middle of the paragraph, but let me know what you think.
It occurs to me that there is a problem with this article at the moment in the arrangement of the material under the various section headings. Most stuff seems to get end up in the health claims section, when some of it clearly belongs elsewhere. I'm going to chop and change it a bit. I'm also going to add a couple of citation needed tags: some of the information presented uses weasel words, and there's at least one statistical claim with no citation.

Thanks for responding. For brevity lets use (1s1k) for "1 serving=1 kilo".

  • Consumer orgs cannot compare to medical/science orgs in evaluating health data. I got a copy of the article. This org only reviewed data available on the internet. There is no author posted for the article. It is written in the same manner as the web article. A clear biased is displayed in "Don't believe everthing you hear..." There is an abundance of peer-reviewed research on wheatgrass and wheatgrass components (eg. tocopherol succinate) not available on the web, that they omitted. That would require a trip to the library. I would expect that they would have made that effort. Certainly a peer-reviewed article would have done the research before writing this kind of review.
  • I think the Cultivation section is great. However I'm mot sure the last sentences belong in that section.
  • Seperating the 1s1k statement from Schnabel's statement makes sense. The 1s1k comparison needs clarification. The fact that one or two nutrients are higher in broccoli then wheatgrass doesn't negate the statement, at least not completely . I am thinking of adding a chart with comparisions of a broccoli, wheatgrass juice and powder to help clarify.
  • Schnabel's statement is just as much a health claim as is the 1s1k statement. The "aforementioned claim most likely originates" is a guess as far as I can tell. Perhaps it should read "The aforementioned claim may have derived" or something to that effect. Anthon01 17:20, 30 October 2007 (UTC)[]
  • What is "1 serving of wheatgrass?" I don't thinks that clear. Also Choice Mag. compares 1 serving of wheatgrass to 30 gm. of spinach or broccoli. Why 30 gm? I think because they are comparing it to 1 oz. of wheatgrass juice which is 28.35 gm. which rounds out to 30 gm. The reference to a garden salad is problematic. I think it makes more sense to stick to single nutrient comparision. Makes it easier to do the numbers. Take a look at this: Wheat Grass Nutrient Levels compared with fresh green vegetablesAnthon01 20:10, 30 October 2007 (UTC)[]
I'll just make a couple of quick points, I have to get to work:
  • It's good that you have a copy of the article - do you have the original print version though? It's my recollection that the authors of the articles are listed somewhere else, I think at the start of the mag.
  • Incidentally, I think they're right to say "don't believe everything you hear", given the fact that retailers frequently make the 1s1k claim, and it seems to be wrong. In the context of a consumer organisation, I think the tone is appropriate.
  • I like the chart, but we can't really use the stats for dried wheatgrass as they come from a retailer. I had info from retailers up here in the early days of the article and it was removed. I don't think this source is reliable in this context, it should be supported by an independent source.
  • I'm not sure about the last sentences of the cultivation section either.
  • "The aforementioned claim may have derived" - sounds good.
  • 1 serving = 30ml, we use metric measurements. The article originally said 30ml, I'm not sure when or why it was removed. Pacey 22:01, 30 October 2007 (UTC)[]

In response

  • The article looks like the original mag sheet. pg 24-25.
  • I agree the tone fits a magazine format. "Don't believe everything you hear" fits the 1s1k claim. However the article wasn't referring to that claim. It reads "don't believe everything you hear or read, very little good quality evidence exist to support the extravagant claims made for the benefit of wheatgrass." The 1s1k is easily refuted with the available evidence. The other claims are not currently refuteable, in fact the evidence available supports or partially supports many of the claims. I don't think you would accept "Don't believe everything you hear" anywhere in this article. That's why I have a problem with the reference.
  • I referenced a book for the data in the chart.
  • I originally removed your 'broccoli' and 'salad' references to Schnabel's statement because I believe that his statement was generally correct if WG powder was the source of wheatgrass. The chart supports that contention and clearly refutes juice as the source. You seperation of 1s1k is a good idea, and certainly it makes sense to refute the 1s1k claim. A better way to refute it is by comparing more then just a few nutrients. —Preceding unsigned comment added by Anthon01 (talk • contribs) 21:48, 31 October 2007 (UTC)Anthon01 21:54, 31 October 2007 (UTC)[]

Factual accuracy[edit]

I would like to see objective research backing up the following claims:

"Wheatgrass grown under artificial conditions indoors in trays does not have the proper balance of nutrients found in wheatgrass grown outdoors under natural conditions"

"Growing wheatgrass in a tray in warm greenhouse conditions is not optimal and is certainly not natural"

"The chemical composition is not balanced"

"the juice from this "artifically grown" wheatgrass tends to have a bad flavor as well as a high bacteria and mold content which is the usual cause of the nausea"

As it stands, most of these claims are poorly defined. Under what standards do we judge wheatgrass production to be optimal or suboptimal? Where is the evidence indicating higher bacteria and mold content for wheatgrass grown indoors? Let alone evidence suggesting that this is the cause of nausea, or even that indoor wheatgrass causes more nausea than outdoor wheatgrass. As for being "not natural", similar arguments could be made for the outlawing of pants. This section reads like a new-age manifesto. --Unknown

RESPONSE TO ABOVE:

Until the information was added about the importance of growing wheatgrass naturally, this piece did read like a "new-age manifesto." The additional information about the importance of growing wheatgrass as nature intended was obviously designed to combat the newage nonsense about growing wheatgrass indoors in trays.

It should obvious to anyone that plants forced to grow 20 times faster than nature intended in temperatures that are three times warmer than nature intended are not as nutritious as plants grown under natural conditions. The photographs of the pale hot house wheatgrass being fed into a juicer compared with the dark green wheatgrass growing in the winter outdoors should prove to anyone who understands even elementary agriculture and nutrition that tray-grown wheatgrass is not as good as the real thing. Since you wrote the above, a link has been added comparing hot house wheatgrass with the wheatgrass grown under natural conditions.

For more scientific evidence that addresses your concerns, an excellent review of literature on wheatgrass and other cereal grass is Cereal Grass - What's in it for You. This review includes more than 130 scientific references in the bibliography.

Regarding the problem with mold in growing wheatgrass under unnatural conditions, even Ann Wigmore agreed that mold is a problem with wheatgrass grown indoors in warm conditions. Mold is a well-documented problem, and several hot-house operations have been shut down because of it. Since you wrote the above, an additional link has been added that also addresses the mold problem. --Unknown

Another link to the mold problem: http://www.cityfarmer.org/wheatgrass.html

To help with the problem I've added "Citation needed" to the sentences that are particularly problematic. I'm not saying that all of these marked claims are wrong, but it is without question that they are currently unsupported by the article as written. Match facts with credible sources. The book you mention does not appear to have an index and the table of contents is of no help in finding information about key claims, vis, the relative occurrence of mold on indoor versus outdoor wheatgrass, the nutrient content of spring wheatgrass grown indoors for 30 days vs spring wheatgrass grown outdoors for 30 days, whether mold is in fact the cause of any naseau, or whether nausea is more common for indoor vs. outdoor wheatgrass, etc. If you read carefully, you will agree that the reference listed for "Mold and wheatgrass" does not address any of the above issues. It is half anecdotal stories, and the other half is irrelevant to the main problems with this section. Please provide proper references if available. I have also deleted usage of biased phrases like "true wheatgrass" and "real wheatgrass", as such would imply the existence of "false wheatgrass", which is not a scientiffic position. --128.113.89.58 18:46, 9 July 2007 (UTC)[]

Regarding: "It should obvious to anyone that plants forced to grow 20 times faster than nature intended in temperatures that are three times warmer than nature intended are not as nutritious as plants grown under natural conditions."

This is patently untrue, should not be obvious, and makes no sense whatsoever. The cellular structure of the plant controls its nutritional content - not how nature may or may not have "intended" it to grow." In fact, the mold issue relates more specifically to how long the plant is allowed to remain in place (planted) versus being harvested. That is, once at maturity, the plant slows its growth dramatically. At this point, mold becomes an issue with respect to the plant becoming inert and a good substrate for parasitic organisms.


Regarding this whole article - it is completely inaccurate and cites no GOOD scientific studies. What it should say is that wheatgrass advocates claim all these crazy health benefits, but there has yet to be any substantiated evidence of any of these claims. Wheatgrass is just grass.76.26.157.210 01:54, 22 August 2007 (UTC)[]

RESPONSE TO PRECEDING COMMENT

The link you mentioned above comparing tray grown to field grown is in my opinion inaccurate. It compares 1 oz. wheatgrass juice to 1/8 ounce (3.5 gms) PINES Wheat Grass Powder. Wheatgrass juice is 19/20ths water. If you remove the water, you are left with 1.42 gms of powder. From 2 oz. of juice you get 2.84 gms. of powder. 2.84 gms makes the tray grown equal to or superior to the powder in almost all nutrients.

Much of the commentary in this article is scientifically unsubstantiated and/or lacking references. The writer(s) are guilty of doing the same thing that the advocates of wheatgrass are accused of doing. Also, keep in mind that 85% of medical procedures are also 'unproven.' --Anthon01 17:39, 30 September 2007 (UTC)[]

And Also: You did fine until this "Wheatgrass is just grass." What does that mean? Oxygen is just oxygen, right? --Anthon01 18:32, 30 September 2007 (UTC)[]


Regarding the first paragraph: "Wheatgrass is a young plant of the genus..." There is a distinction between wheatgrass and wheat grass. Wheatgrass is grass grown indoors in trays for about 10 days and then freshly juiced. Wheat grass is grass grown outdoors in the ground. Please see the following http://www.wheatgrass.com/faq/factsheets/wheatgrassfactsheet.php

Regarding this statement "The unprocessed plant contains fiber, which promotes colon health."

The fiber link to cancer is no longer a given. Several large studies failed to show any link between fiber and colon cancer. See http://www.hsph.harvard.edu/nutritionsource/fiber.html --Anthon01

Nutritional Data[edit]

Librarianofages: Nutrition Data on your link is poor as almost all the items are empty. It gives the impression that there isn't much nutrition in wheatgrass, when in fact it is just a lack of data. Please check http://www.wheatgrass.com/faq/factsheets/analysisjuice.php69.177.178.105 14:47, 11 October 2007 (UTC)[]

The table for "Nutrient comparison of 15 lbs. of wheatgrass juice, dried wheatgrass and 350 lbs. of broccoli" is bizarre, misleading, and irresponsible. There is no clear source for the claimed nutritional content of dried wheatgrass. You cannot take the nutritional content of fresh wheatgrass juice, multiply it by 20, and claim that's the figure for dried wheatgrass; you have to dry the grass and directly analyse it. The drying process is likely to significantly change the nutritional content, and even if it doesn't such a result must be demonstrated. Furthermore, the drying process is unlikely to remove all the water from the wheatgrass, so multiplying by the fraction of water will prove inaccurate. I don't have access to the cited source, so it's possible it answers these caveats, but some demonstration of this would be very useful, or a reference to an independent government or scientific authority.

Also, why is the chart for 15 lbs wheatgrass and 350 lbs broccoli? Is this designed to make comparison as hard as possible? —Preceding unsigned comment added by 193.172.19.20 (talk) 13:43, 30 January 2008 (UTC)[]

I would like clarification on allergic reactions to gluten which is found in wheat. This is derived from wheat, shouldn't that mean that wheat grass contains gluten, even in the powder form? In the allergy section it should be made clear, as there are health products being sold with this powder as an ingredient that state "does not contain gluten".

Agropyron a relative of Triticum? Both graminae but beside this? Agropyron repens, I know, its a terrible weed with a very low nutritive value. In comparison to wheat, the bread making cereal? No comparison...

Health Claims[edit]

"These claims have neither been proven nor disproven." has been replaced with "these claims have not been proven." The burdon of proof should be on those who consider wheatrgrass to be beneficial

Nice edit.

--AaronOfAbsalom 12:12, 28 July 2006 (UTC)[]

I disagree. Wikipedia is a source of information, it is not a claims court. If too little research has been done to make any substantial conclusions about wheatgrass, the article should simply say so. --Karuna8 15:16, 10 December 2006 (UTC)[]
The point is that unproven claims are not somehow different from undisproven claims. "Neither proven nor disproven" is redundant. If a claim has been disproven, subsequent efforts to prove it are written off. If a claim is proven, then it's been strengthened to the point where it is generally accepted as fact and nobody bothers trying to disprove it. If something has not been proven, it doesn't bear mentioning that it has not been disproven. It smacks of a hasty attempt to make it look good in spite of a lack of evidence. --SquidDNA 13:53, 23 July 2007 (UTC)[]
Saying something has been neither proven nor disproven in this case is misleading, as medical science cannot disprove that wheatgrass is beneficial. Swax 05:57, 16 January 2007 (UTC)[]
Neither can medical science disprove that I have a solid gold house that I won't show to anyone. You can make any ludicrous claim you want to, the burden of proof is always on YOU, not on someone else to disprove. This is how science works. --SquidDNA 13:53, 23 July 2007 (UTC)[]
I don't mean to nitpick, but I have to point out that science cannot prove anything, it can only disprove. If you want to "prove" something, the best you can hope for is to disprove the opposite. This is a basic premise of the scientific method --- hypotheses are postulated, and then scientists go about trying to disprove them. If, after rigorous attacks by scientists, the hypothesis is still consistent in explaining a phenomenon, the hypothesis can then be considered to be a theory (or, "proven true" in the eyes of casual observers). However, even a theory cannot formally be considered to be proven true, because science cannot do this.

With this in mind, when someone hypothesizes anecdotally that wheatgrass has a certain beneficial health effect, it cannot be immediately considered to be "true", and it falls upon scientific skeptics to go about setting up experiments to try to disprove this claim. If, after a number of credible, unbiased, and rigorously structured studies have been performed which demonstrate no positive effects of wheat grass on health issue X, then the hypothesis can be discarded, and considered unproven. The same goes the other way. If someone hypothesizes that wheat grass does not have a certain beneficial health benefit, then it is up to scientists to create expeeriments to try to disprove that. If these experiments show positive health effects of wheat grass, then the original hypothesis can be discarded and wheat grass can be considered to be beneficial. These experiements are not at all difficult to do; this is the stuff of standard empirical medical study, and I'm surprised that so few of them have apparently been performed to cite in this article, based on the comments on this board.Kram-bc 16:43, 14 October 2007 (UTC)[]

I don't mean to nitpick but you have NO idea what you are talking about. I guess that is the general consensus on an edit page for wheatgrass. Science proves nothing. When I perform a fine needle aspiration of a lymph node and diagnose PJP in a patient that must disprove him being healthy. Of course it doesn't prove that he has PJP. Please don't type if you don't know what you are typing about.

As far as research goes, wheatgrass can't be patented; without patents research money is limited. However there are a few studies that support some of the claims.

Health Benefits[edit]

I've started work on a health benefits section, relying particular on a recent article in Choice magazine which is primarily focussed on debunking myths about wheatgrass. I've noticed that the article's available online, I'll try and continue to address the health claims from that article and other sources if I get time. If someone feels like getting stuck into it though, go ahead.

Oops, didn't sign... Pacey 09:43, 6 September 2006 (UTC)[]

I've removed this from the Health Benefits section - "It is also worth noting, however, that while a kilogram (about 2 pounds) of vegetables may contain more vitamins and nutrients than a shot of wheatgrass, a kilo of vegetables is an amount that very few people can eat in one sitting, which makes it impractical in every day life. Also, a kilogram of vegetables contains over 300 times the amount of calories in a shot of wheatgrass." The first sentence is irrelevant, since a small salad contains more nutrients than a shot of wheatgrass, and most people can fit a small salad into their daily meals. The calories statement needs a source. Pacey 00:28, 24 October 2006 (UTC)[]

wow, cleanse the liver? prevents hair loss? they didn't teach us about "cleansing the liver" in medical school. I'm sure Wheatgrass is healthy for you and a good addition to your diet but leave out these bullshit claims, poorly written article that includes trivial information throughout in my opinion. Rob

Questionable neutrality[edit]

The only sourced information on this page are articles critical of wheatgrass. Someone has to take the time to find reputable counter-opinions. Further, there is clear bias in the way the article is written: it lists so many anecodotal examples of health benefits in a row as to insinuate that we're witnessing a placebo effect. Someone needs to take the time to find which health benefits are more and less supported by research. This someone is not me. Whoever added all the references to the single negative source should have found at least one reputable counter-source to not make the article so terribly imbalanced. Hpatenaude 16:23, 7 September 2006 (UTC)[]

Addressing your concerns

  • Firstly, with regard to the sources, I did actually put up some citations to positive sources but they were removed because they were links to commercial websites. Almost everyone supporting wheatgrass is also selling it, or selling some other kind of health program associated with it. The problem is that there aren't any reputable scholarly sources supporting wheatgrass, as far as I could ascertain. Having said that I don't think there's anything wrong with citing claims made by companies, particularly where competing claims are also being presented. I'll check Wikipedia's policy in this regard and I may reinstate some of those sources at a later date. Had I been able to find any scholarly sources supporting wheatgrass consumption I would have used them. As an aside, the transcript of the Landline article is, for the most part, fairly positive about wheatgrass. You only need look at the title of the article to establish that: "healthy for the body and bank account."
  • Secondly, I dispute that there is a bias in the presentation of the material. It is an empirical fact that many proponents of wheatgrass claim that it has some or all of these health benefits. Putting those claims together isn't intended to discredit them in any way. It would simply look messy, in my opinion, to list each of the claimed health benefits seperately. If you feel they should be listed in this way, go ahead and do it. Furthermore, the only health benefit that is directly disputed here is that '30ml of wheatgrass is equivalent to a kilo of veggies'. This claim was included here because it is commonly made, and it is, according to the only studies I could find, demonstrably untrue. I could find no evidence to support the claim.
  • Thirdly, you complain about "all the references to the single negative source". The source you're referring to is only cited three times, and one of those citations is positive: the assertion that there is a lot of anecdotal evidence supporting the benefits of wheatgrass use.

Finally, I should point out that the article does nothing but assert facts. I am aware that an assertion of fact can still be considered non-neutral according to Wikipedia's policy guidelines. As such I am removing the only pieces of the text which I feel may fall foul of this distinction - The phrase "these claims are untrue" and the wording of the final sentence in the section. I will then remove the 'neutrality disputed' tag. Pacey 09:36, 10 September 2006 (UTC)[]

I should also emphasise that if you still feel the article isn't from a NPOV, feel free to put the tag back on. Pacey 10:20, 10 September 2006 (UTC)[]

This biased description of a "fast food salad" has no citiation (or basis in fact) and should be removed: "however due to the high level of processing and lacing the vegetables with chemicals to preserve the salads for several days, most of these nutrients are stripped from the salads." 1.

Isn't it Wheatgrass Juice?[edit]

This whole article seems to be about wheatgrass juice, and yet Wheatgrass juice links to Wheatgrass. Seems backward. --Karuna8 20:53, 22 December 2006 (UTC)[]

Wheatgrass is different from wheat grass. Wheatgrass is grass grown indoors in trays for about 10 days and then freshly juiced. It is used for therapeutic purposes. --Anthon01 03:11, 1 October 2007 (UTC)[]

Objection[edit]

User:Drbrucek added this comment to the Usage section of the article. I moved it here:

The average dose listed here is larger than the "large" size you can buy at a "juice" bar. There needs to be more citations about that 2-4 ounce size as well as taking it 5 times a day. That does not sound right.

--Heron 16:47, 14 April 2007 (UTC)[]

As anyone who has researched and personally felt the beneficial effects of juicing understand is that by removng the pulp, seeds and solids portions of the plant you are concentrating the 'lifeblood' of the plant. This makes the vitamins, minerals and trace elements, which are mostly found and suspended in the plant juices readily available for ingestion/digestion. This is not theory. Amounts of unuseable solid material from juicing are enormous. As much as 97% (by volume) is compost, leaving only concentrated liquid. Liquid is a freindly and fast form of nutrition available to the body. At times too fast. As Dr. Lendon Heinerman suggests it's like putting 200 octane fuel in your car, the danger is that the engine may not be able to handle it. If you make a drink that is basically from a natural and beneficial food without chemical or genetic processes wouldn't it follow that it to would be good for you?

What you call "compost" consists of many nutrients that are not removed by juicing. It also consists of extremely important VEGETABLE FIBER, the lack of which has been shown to be a major reason that colon cancer is the second leading cause of cancer death. You sound like the folks a century ago who said that the husks of wheat were "indigestible compost" and should be thrown away and that we should only eat the white centers of the wheat berry. They missed the point that many nutrients are contained in the wheat bran as well as valuable fiber. Maybe you prefer a diet of sugar and white flour and other processed foods and juices, but for me I'll stick with WHOLE FOODS that our bodies were designed to consume.

  • If you notice the Wheatgrass (disambiguation) page, wheatgrass is many different plants. Also if you haven't yet, please lookup Wikipedia's Common wheat also know as triticum aestivum or wheatgrass. This is the plant that is used to make wheatgrass juice. In a sense the wheatgrass page already exist under Common wheat. We could add a section to Common wheat, that discusses the use of the immature plant for juicing. I'm not sure that would go over well. We could write a page on the immature plant, but I'm not sure if that's the best way to do this as the only value of the immature plant is for juicing, powdering or tableting it. What do you think?
  • Please lookup the first section, Deciding to disambiguate under Wikipedia:Disambiguation. If you google wheatgrass, there is almost nothing on it except wheatgrass juice. So the popular meaning of wheatgrass is in reference to wheatgrass juice.
  • I think you suggestions as to the introduction make sense. Taste smell, color appearance, all make sense. Are you suggesting that discussing why and how consumers get Wheatgrass in the introduction is inappropriate?
When did you mention this before? I must have missed it. Anthon01 (talk) 04:28, 20 November 2007 (UTC)[]

B12[edit]

the link in the citation on vitamin b12 content shows no such thing. it just links to a nutrition database search page that produces no results when wheat grass or anything similar is entered. if someone can't find a better source i'll delete it in a few days--Mongreilf (talk) 10:53, 4 January 2008 (UTC)[]

Actually I will fix the link. Anthon01 (talk) 14:13, 4 January 2008 (UTC)[]
I'm sceptical, but don't have access to the citation to argue, it seems to be a health food proselytising book, which are often not reliable though this isn't enough for me to want to erase the edit. The Vegan Society insists there are no reliable vegetable sources for B12 [1], and the wikipedia article on Vitamin B12 lists a few claimed vegetable sources that have proved spurious - including barley grass. AFAIK vitamin B12 is synthesised only by bacteria and wheat grass may have vitamin B12 in it by virtue of soil bacteria that are present on the plant. The wheat grass I use (Garden of Life brand) makes no claim to include any vitamin B12--Mongreilf (talk) 18:28, 4 January 2008 (UTC)[]
I see your concern. Lets see what else I can dig up. Anthon01 (talk) 22:35, 4 January 2008 (UTC)[]

This still needs more/better sources. A single book isn't good enough when there are plenty of sources stating that b12 is not reliably found in plants. Perhaps a statement saying that the information is disputed could be added. If it helps, Steve Meyerowitz who is the author of the referenced book takes his information from Dr. Yoshihide Hagiwara Muleattack (talk) 20:42, 12 October 2011 (UTC)[]

Health claims[edit]

I'm concerned that none of the sources meet WP:MEDRS (the studies are old and pilot studies). It might be helpful to get some perspectives from WP:FTN. --Ronz (talk) 03:29, 2 August 2010 (UTC)[]

Indoor growing and mold[edit]

This section smacks of WP:NOTHOWTO to me. It's only of use to those who want to sprout wheatgrass themselves. Muleattack (talk) 19:24, 1 October 2011 (UTC)[]

Chlorophyll in human diet[edit]

Sources 6 and 7 don't tell us anything about the benefits of chlorophyll in the human diet. The first is a study on rats and the second one actually makes a point of noting that the evidence it's reviewing does not pertain to chlorophyll consumed orally. Thus neither of them say anything about the human diet.

I'll fix it unless there's any objections.

Also, do we have a source for that bollocks about chickens' egg production being doubled by wheatgrass consumption? One that hasn't been written by someone trying to sell wheatgrass products. — Preceding unsigned comment added by 81.102.43.72 (talk) 09:10, 31 August 2012 (UTC)[]

"5000 year-old History"[edit]

I have been trying to find a source for the claim at the start of the history section:

Wheat grass can be traced back in history over 5000 years, to ancient Egypt and perhaps even early Mesopotamian civilizations. It is purported that ancient Egyptians found sacred the young leafy blades of wheat and prized them for their positive effect on their health and vitality.[1][non-tertiary source needed]

It seems there are plenty of things linking wheat to Egypt, but as for wheatgrass and, specifically, the historical health-use claim, things are trickier. The two links cited by the tertiary source given have both decayed. One of them doesn't mention it and the the other (presumably the intended reference) is by "Dr Wheatgrass", a "wheatgrass based skin care products" retailer. The last available version of it is a bunch of links, of which I've tried some but don't see much point as I doubt it would qualify as a reliable source.

There are a bunch of health sites which say similar things but all use phrasing very similar to Wikipedia's own, were put up later than the edit, and give no other related information, mentioning Egypt and Mesopotamia only tangentially. This is also the case for the one post-edit reference found on Google Books. There is also one from before the edit, in The Complete Guide to Growing and Using Wheatgrass, but since it is not a history text, references the claim only once, does not provide a source, and includes a disclaimer about the possible inaccuracy of its contents, I am happy to discard it.

I think the claim is apocryphal, and have taken it down until someone can provide a real source. ─ ReconditeRodent « talk · contribs » 22:57, 23 March 2018 (UTC)[]

Pascopyrum

Genus of grass

Pascopyrum is a monotypic genus of grass containing the sole species Pascopyrum smithii, which is known by the common names western wheatgrass and red-joint wheatgrass, after the red coloration of the nodes. It is native to North America.

Distribution[edit]

This is a sod-forming rhizomatous perennial grass which is native and common throughout most of North America. It grows in grassland and prairie in the Great Plains, where it is sometimes the dominant grass species. It is the state grass of North Dakota, South Dakota, and Wyoming.

Ecology[edit]

It is a valuable forage for animals such as bison and black-tailed prairie dogs, and it is good for grazing livestock.[1] It is used for revegetation of disturbed and overgrazed habitat, and many cultivars have been developed to suit various conditions,[1] including low-maintenance lawns. Wheatgrass generally tolerates mowing to four inches, but does not tolerate shade. Healthy stands may crowd out other species, making it more suitable for monoculture plantings.

Agropyron cristatum

Species of grass

Agropyron cristatum, the crested wheat grass, crested wheatgrass, fairway crested wheat grass, is a species in the family Poaceae. This plant is often used as forage and erosion control. It is well known as a widespread introduced species on the prairies of the United States and Canada.

History[edit]

Agropyron cristatum is one of several closely related grass species referred to as crested wheatgrass. It is unable to hybridize with its similar relatives, as it is a diploid species, whereas its closest relative, Agropyron desertorum, is a tetraploid species.[1] It was introduced from Russia and Siberia to North America in the first half of the twentieth century, and widely used to reseed abandoned marginal cropland undergoing varying degrees of soil erosion and secondary succession.[2]A. cristatum is very long lived, with stands often remaining productive for 30 years or more.[3]

Agropyron cristatuminflorescence

Description[edit]

Agropyron cristatum is a densely tufted grass, with culms ranging from 30–50 cm high at maturity. Its sheaths are scabrous or the lowest ones pubescent. Its blades are up to 8 mm wide and scabrous to pubescent above. Its spikes are flat and range from 2–7 cm long, with spikelets ranging from 8–15 mm long, being 3–5-flowered, densely crowded, and spreading to ascending. Its glumes are 4–6 mm long, awn-tipped, and its lemmas are 6–8 mm long and either awnless or awn-tipped.[4]

Agropyron cristatum is known among other grasses and wheats for its relatively high granivory. Granivory, or granivores, describe the interaction between animals and seeds. Agropyron cristatum's high granivory indicates that animals feed on the seeds of the plant as their primary, or even exclusive, food source. Although this raises concerns about the plant's continued ability to reproduce if its seeds are all being consumed, the high granivory of this species does indicate that Agropyron cristatum is an important food source.[5]

Habitat[edit]

Agropyron cristatum is best adapted to dry rangeland conditions and is most frequently found in such circumstances. It prefers from 23 to 38 cm of precipitation per year,[6] but can tolerate more moisture on favourable sites, extending its range into tundra and taiga conditions[7] and elevations up to 2000 m above sea level in the southern portions of its adapted area.[8] It prefers well drained, deep, loamy soils[9] of medium and moderately coarse texture, including Chernozemic, Solonetzic, Regosolic,[10]Brunisolic and Luvisolic soils.[11]A. cristatum can tolerate salinity in the range of 5 to 15 mS/cm[12] and prefers moderately alkaline conditions.[10] It has low to medium fertility requirements.[13] It will not tolerate prolonged flooding.[1]

Agropyron cristatum is the most shade-tolerant of the crested wheatgrasses, but does best in open conditions.[11]A. cristatum is extremely drought tolerant.[14] It achieves this drought tolerance by starting growth very early in the season, then going dormant from seed set until fall when it will exhibit vegetative regrowth if moisture is sufficient.[2]

A recent study has shown that invasive populations of Agropyron cristatum have spread across the upper U.S. as well as southern Canada, and the invading Agropyron cristatum populations have been found to have a higher granivory than native grasslands and they maintain dominance even when native grassland species are reintroduced.[5] This current study indicated that the increased granivory of Agropyron cristatum did not contribute to its competitive success. The study did show that although A. cristatum was found to have higher granivory, after 2 years the difference between A. cristatum's granivory and that of native species lessens, and that there was no apparent preference among the animals for either wheat.[5] Therefore, the factors responsible for Agropyron cristatum's high granivore content are still relatively unknown.

Agropyron cristatum is very tolerant of grazing,[8] although under dry conditions new stands should be protected from grazing for at least two years as the seedling are slow to develop. A. cristatum can be damaged by several fungi, including leaf and stripe rusts,[10]snow mold and some arthropods including black grass bugs (Labops sp.) in pure plantings.

Uses[edit]

Agropyron cristatum has been bred into many cultivars selected for attributes ranging from forage yield to drought tolerance to turf types that will exhibit more pronounced degrees of rhizomatous growth habit.[10] It has been and continues to be, widely used in both agricultural and industrial reclamation activities.[10]

Agropyron cristatum is known among other grasses and wheats for its relatively high granivory. Granivory describe the interaction between animals and seeds. Agropyron cristatum's high granivory indicates that animals feed on the seeds of the plant as their primary, or even exclusive, food source. Although this raises concerns about the plant's continued ability to reproduce if its seeds are all being consumed, the high granivory of this species does indicate that Agropyron cristatum is an important food source. Studies have been conducted in search of the cause of Agropyron cristatum's increased granivory, but as of yet a high relative granivory has not been proven to be a unique characteristic of A. cristatum, and could actually be attributed to factors other than the plant's genome, such as environmental conditions.[5]

One promising factor that could lead to, and be responsible for, increased granivore in Agropyron cristatum is a certain genetic difference found on chromosome 6 of plants with a higher granivore content.[15] Plants with a translocation on chromosome 6P yield wheat of greater weight and longer spike length than those without the mutation.[15]Agropyron cristatum possesses higher tiller number, higher floret numbers, and greater resistance to various pathogens such as wheat rusts, powdery mildew, and barley yellow dwarf virus than many of its close wheat relatives.[15] It has been used to cross-breed with other species of grass and wheat to transfer a greater disease resistance to them, as well as enhance their properties as a food source.[15] This cross-breeding involves the transferring of the chromosome 6P translocation to the species it is cross-breeding with.[15] Chromosome 6P of A. cristatum has also been proven to play an important role in regulating fertile tiller number and it possesses positive and negative regulators of tiller number.[16] These regulators were specifically found to be on the 6PS and 6PL chromosome arms.[16] High floret numbers and number of kernals per spike is controlled by genes located on chromosome 6P of Agropyron cristatum.[17]Agropyron cristatum’s genes can be used to instill leaf resistance in other species of wheat.[17] Three backcrosses between Agropyron cristatum and Aegilops tauschii produces a number stable, fertile lines of Aegilops tauschii that then has resistance to leaf rust.[17] Also, multi-spike cultivars of A. cristatum have been found to be more stable agronomically and achieve higher yields than cultivars with large-spike type.[16]

It is an easy grass to establish by seed, having both high germination rates and high seedling vigour.[18] It also establishes rapidly relative to many other grasses.[10] Under non-irrigated conditions in low precipitation areas, Crested Wheatgrasses are consistently some of, if not the, highest yielding and persistent of domestic forage grasses. However, A. cristatum is lower yielding, although it is slightly more palatable, relative to other Crested Wheatgrasses.[7]

Agropyron cristatum shows an immense toughness to a wide range of environmental conditions. Agropyron cristatum can be grown in cold temperatures, drought conditions, and relatively high amounts of salinity.[19] It also has a resistance to barley yellow dwarf, wheat streak mosaic viruses, and leaf rust disease as well as containing high protein content.[19]

Agropyron cristatum is a highly competitive and persistent plant in drier areas, and has a moderate ability to spread by seed. As such, its use in and adjacent to remaining natural grassland communities within its adapted areas in outside its native Eurasian distribution has come under criticism as a factor in natural grassland biodiversity loss, although the subject is still being studied.[20] One such fear is that its seedlings' emergence does not decrease under herbicide treatment.[21]

Tenacity[edit]

The importance of Agropyron cristatum is often undermined, as the plant has not been domesticated for modern agricultural use. Agropyron cristatum’s ability to withstand various environmental and biological blighting makes it a truly unique and valuable organism. Recent studies highlight the importance of A. cristatum in future agricultural development because it exhibits several desirable traits for the improvement of domesticated wheat.[22] While some of these traits may be related to yield production of the wheat, other significant traits include biotic and abiotic stress resistance genes that enable A. cristatum to grow proficiently. The importance of this knowledge is that researchers can use this genetic information regarding stress resistance genes to introduce new desirable traits in other domesticated wheat species that aid their growth in harsh environments. Ultimately, this leads to better yields for more human consumption.

The phenotypic success that Agropyron cristatum experiences is primarily due to the success of its root system. Recent studies show how root development contributes to the competitiveness of A. cristatum by testing its ability to flourish over other forms of vegetation in grassland environments.[23] These studies provide data on how long the roots grow and how concentrated soil volume becomes with roots of A. cristatum.[23][24] The results shows that A. cristatum typically allocates more of its biomass in its roots than its shoots when compared to other grassland species. Interpretation of this data suggests that because A. cristatum has a better foundation, it can outcompete other species for resources.[23][24] These reports give significant insights into why A. cristatum is so competitive and why the development of this species could be a valuable asset to the food production as a perennial plant that is very competitive with its roots.[24] In addition to this data, new research implies that whatever genes are enabling the roots to beat out the competition are homogeneous in nature (therefore more easily passed down through generations) and is the reason the species is as dominant.[23] Once these genes become identified, agriculturalists can seek to implement them into genetically modified versions of wheat species to create a more durable and successful domesticated wheat species in our limited environment.

Today, researchers can annotate important functional genes that may be valuable for human use in the field of agriculture. This can be accomplished by utilizing next-generation sequencing techniques to analyze transcriptomes and genomes.[22] Studies show that A. cristatum contains an abundance of protein family domains including nucleotide-binding domain-ARC (NB-ARC), AP2 domains, Myb family transcription factors (Myb), and late embryogenesis abundant (LEA) proteins that are all stress resistance genes.[22] Specifically, NB-ARC proteins deal with general immune resistances, AP2 domains relate to cold temperature and drought resistance, Myb proteins also aid in drought resistance but also help in salinity stress, and LEA genes generally involve resistance from other abiotic stresses.[22] With this information, the next step is to actually introduce versions of these desirable genes into domesticated species. The results from a 2013 study displays the effects of introducing translocations between those desirable traits from A. cristatum to modern wheat species.[25] Using the method of intergenic translocations, the research shows that successful integrations have been completed and that those plants do in fact grow normally as well.[25] Another method from a successful 2015 study involves the use of intergenic hybridization to introduce resistance genes associated with leaf rust.[26] To sum up, the numerous biotic and abiotic resistance genes that A. cristatum presents leads to the success of the species which could and can be applied to modern day food production of the wheat domesticated species.

Wheatgrass

Freshly sprouted first leaves of the common wheat plant

For other uses, see Wheatgrass (disambiguation).

Indoor-grown wheatgrass 8–10 days before harvest.
Speltgrass grown outdoors. With a deeper green color than wheat.

Wheatgrass is the freshly sprouted first leaves of the common wheat plant (Triticum aestivum), used as a food, drink, or dietary supplement. Wheatgrass is served freeze dried or fresh, and so it differs from wheat malt, which is convectivelydried. Wheatgrass is allowed to grow longer and taller than wheat malt.

Like most plants, wheatgrass contains chlorophyll, amino acids, minerals, vitamins and enzymes. Claims about the health benefits of wheatgrass range from providing supplemental nutrition to having unique curative properties, but these claims have not been scientifically proven.[1]

Wheatgrass juice is often available at juice bars, and some people grow and juice their own in their homes. It is available fresh as produce, in tablets, frozen juice, and powder. Wheatgrass is also sold commercially as a spray, cream, gel, massage lotion, and liquid herbal supplement. Because it is extracted from wheatgrass sprouts (that is, before the wheat seed or "berry" begins to form), wheatgrass juice is gluten free, but some dietitians recommend that those with celiac disease avoid it due to the risk of cross-contamination.[medical citation needed]

History[edit]

Wheatgrass is traditionally used in both Persian and Indian festivals and rituals. Hindu sow wheat or barley seeds on the first day of Navratri pooja and offer the saplings to the mother goddess on the last day as part of the rituals. However, the consumption of wheatgrass in the Western world began in the 1930s as a result of experiments conducted by Charles Schnabel in his attempts to popularize the plant.[2] By 1940, cans of Schnabel's powdered grass were on sale in major drug stores throughout the United States and Canada.[3]

Ann Wigmore was also a strong advocate for the consumption of wheatgrass as a part of a raw food diet. Wigmore, founder of the Hippocrates Health Institute, believed that wheatgrass, as a part of a raw food diet, would cleanse the body of toxins while providing a proper balance of nutrients as a whole food. She also taught that wheatgrass could be used to treat those with serious ailments.[4]

Cultivation[edit]

Outdoor-grown wheatgrass grows slowly through the winter in a climate like that of Kansas in the United States.

Wheatgrass can be grown indoors or outdoors. A common method for sprout production indoors is often on trays in a growth medium such as a potting mix. Leaves are harvested when they develop a "split" as another leaf emerges. These can then be cut off with scissors and allow a second crop of shoots to form. Sometimes a third cutting is possible, but may be tougher and have fewer sugars than the first.[5]

Schnabel's research was conducted with wheatgrass grown outdoors in Kansas. His wheatgrass required 200 days of slow growth through the winter and early spring, when it was harvested at the jointing stage. He claimed that at this stage the plant reached its peak nutritional value; after jointing, concentrations of chlorophyll, protein, and vitamins decline sharply.[6] Wheatgrass is harvested, freeze-dried, then sold in tablet and powdered concentrates for human and animal consumption. Indoor-grown wheatgrass is used to make wheatgrass juice powder.

Nutrition and health claims[edit]

Proponents of wheatgrass make many claims for its health properties, ranging from promotion of general well-being to cancer prevention. However, according to the American Cancer Society, "available scientific evidence does not support the idea that wheatgrass or the wheatgrass diet can cure or prevent disease".[8]

Nutritional content[edit]

Wheatgrass is a source of potassium, dietary fiber, vitamin A, vitamin C, vitamin E (alpha tocopherol), vitamin K, thiamin, riboflavin, niacin, vitamin B6, pantothenic acid, iron, zinc, copper, manganese, and selenium. It is also a good source of protein, with up 8 grams per ounce if consumed in powder form or around 1 g in a "shot" of juice.[9][10] This protein content consists of at least 17 forms of amino acids, including eight out of nine essential amino acids.[11]

The nutrient content of wheatgrass juice is roughly equivalent to that of dark leafy vegetables.
