It is a diploid and can be referred to Agropyron cristatum
Yields of crested wheatgrass (Agropyron cristatum
) and Russian wildrye (Psathyrostachys juncea) have been aggregated.
Suppression of annual Bromus tectorum by perennial Agropyron cristatum
Roles of soil nitrogen availability and biological soil space.
0.273 0.047 forest Agropyron cristatum
Diagnostic taxa: Aegilops triuncialis, Agropyron cristatum
Two selected coal FA, from Montana semi-bituminous coal and from North Dakota lignite, alone or in combination with SPM have been tested as plant growth media (growth media is listed in Table below) for the following plant species: barley (Hordeum vulgare), oats (Avena sativa), rye (Secale cereale), wheat (Triticum aestivum), Regreen; a hybrid between wheatgrass (Agropyron cristatum
) and winter wheat (Triticum aestivum), Triticale; a hybrid between wheat (Triticum aestivum) and rye (Secale cereale),, and perennial ryegrass (Lolium multiflorum).
Pavl.) Henrard and Agropyron cristatum
(L.) Gaertn., which occur today on dry sites in the highly continental, southwestern part of the study area (Yurtsev, 1982).
In May 1998, 4 common grasses on the Plateau, smooth bromegrass (Bromus inermis, BI), siberian wildryegrass (Elymus sibricus, ES), drooping wildryegrass (Elymus nutans, EN), and crested wheatgrass (Agropyron cristatum
, AC) were combined in 3 mixtures with different compositions and seed rates as follows: 38 kg/ha of BI + 56 kg/ha of EN (BI + EN); 38 kg/ha of BI + 14 kg/ha of ES + 23 kg/ha of AC (BI + ES + AC); and 19 kg/ha of BI + 14 kg/ha of ES + 28 kg/ha of EN + 23 kg/ha of AC (BI + ES + EN + AC).
This study examined the difference in infiltration rates between two contrasting grass species, intermediate wheatgrass (Agropyron intermedium (Host) Beauv.), a sodforming grass, and crested wheatgrass (Agropyron cristatum
(L.) Gaertn.), a bunchgrass.
, an introduced [C.sub.3] perennial tussock grass, has been widely planted on the northern Great Plains since the 1930s and now dominates 6-10 x [10.sup.6] ha (Lesica and DeLuca 1996).
Nonnative grasses, such as crested wheatgrass (Agropyron cristatum
), occupy disturbed sites or areas seeded for livestock forage.
The dominant shrubs include Rubus corchorifolius, Lespedeza bicolor, and Elaeagnus pungens and the dominant herbs include Thalictrum aquilegifolium, Carex distachya, and Agropyron cristatum
Common grasses included blue grama, western wheatgrass, tall fescue (Festuca arundinacea), crested wheatgrass (Agropyron cristatum
), mountain muhly (Muhlenbergia montana), Kentucky bluegrass (Poa pratensis), dropseed (Sporobolus) , and squirrel tail (Sitanion hystrix).
Native grasses include bluebunch wheatgrass Pseudoroegneria spicata and Idaho fescue Festuca idahoensis, and introduced grasses, such as smooth brome Bromus inermis and crested wheat grass Agropyron cristatum
, persist in the former agricultural fields.
Photosynthetic carbon uptake increased in higher ploidal levels on a leaf area basis, such as in Agropyron cristatum
(Frank, 1980), Festuca arundinacea (Joseph et al., 1981), and Panicum virgatum (Warner et al., 1987).
