The photo above shows crested wheatgrass as seen along Lakeside Road in Conboy Lake National Wildlife 21, Agropyron was used by several workers as parent material for wheat improvement. According to Smith (i) the following Agropyron characteristics would be of value in the cultivated wheats: 1. Resistance to heat and drought 2. Extreme winterhardiness 3. Resistance to frost 4. Tolerance to alkaline and acid soils 5. Resistance to rusts and smuts.

    Summary. Intergeneric hybrids between Triticum aestivum L. and conventional rhizomatous Agropyron species were produced in variable frequencies. They were recovered in high percentage frequencies for T. aestivum cultivars with A. acutum (%), A. intermedium (%), A. pulcherrimum (%), and A. trichophorum (%).

Niche divergence between Agropyron smithii, C₃, and Bouteloua gracilis, C₄ by Paul Raymond Kemp Download PDF EPUB FB2

Agropyron smithii (a C 3 species) and Bouteloua gracilis (a C 4 species) occur in the same habitat of the shortgrass prairie ecosystem in northeastern Colorado. The hypothesis tested in this study was that the two species differ in their fundamental niches partly as a function of their different physiological responses to temperature and moisture by: measured for Agropyron smithii, increased with irrigation and declined slowly in the six years after irrigation was discontinued.

Within year survival was recorded for early spring cohorts of Agropyron smithii (20 culms) and Bouteloua gracilis (30 culms). Agropyron smithii culm survival was slightly enhanced by all levels of irrigation.

Agropyron cristatum is one of several closely related grass species referred to as crested wheatgrass. Niche divergence between Agropyron smithii 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.

It was introduced from Russia and Siberia to North America in the first half of the twentieth century, and widely used to Family: Poaceae. The identification of the "seeds" 2 of the species of Agropyron is an important problem to the farmer, the seedsman, and the seed laboratory.

Agropyron repens (quack-grass) is recognized as a dangerous weed, and the similarity between the seed of this species and other common but more desirable species of Agropyron gives rise to confusion. The native vegetation is mixed‐grass grassland dominated by blue grama grass Bouteloua gracilis, needle‐and‐thread grass Stipa comata and spikemoss Selaginella densa (Christian & Wilson ).

Agropyron. It is now agreed that Agropyron should be restricted to A. cristatum and its close relatives, i.e., the crested wheatgrasses. There is less agreement on how its members should be treated. The genus is native to Eurasia. The table below is based on Tsvelev's () treatment, with additional information being taken from Yang ( AGSM - Agropyron smithii.

Looking for abbreviations of AGSM. It is Agropyron smithii.
