Asterix and Agropyron elongatum L) were selected as materials for determination of resilience under saline and alkaline conditions.

SCAR marker tagged to the alien leaf rust resistance gene Lr19 uniquely marking the Agropyron elongatum-derived gene Lr24 in wheat: a revision.

However, Convolvulus arvensis, Cynodon dactylon, Agropyron repenc, Chenopodium album and Setaria viridis were the most commonly occurring species, dominating the weed population in the experimental site (Table 8).

Also in Table 2 are several common grasses of steppe patches on south-facing slopes in the taiga of northeastern Asia: Agropyron boreale (Elymus alaskanus), Calamagrostis purpurascens, and Festuca lenensis (Permyakova, 1973; Khokhryakov and Shatkauskas, 1973; Yurtsev, 1982).

Mixed-grass prairie occurs on more mesic sites and low areas and can be dominated by Bouteloua gracilis, Stipa comata, Artemisia filifolia, and Agropyron smithii.

These include common sea-lavender (Limonium vulgare), sea purslane (Halimione portulacoides), and the Poaceae Agropyron elongatum and Puccinellia festuciformis.

As reported in Tilman (1987), the high N addition treatment in these macroplots led to a doubling of plant biomass and the virtually complete dominance of the grasses Agropyron repens and Poa pratensis by the beginning of the experiment in 1989.
