E. sibiricus L., the type species of the genus Elymus, is a perennial, self-pollinating and allotetraploid grass indigenous to Northern Asia, which in some countries can be cultivated as an important forage grass. In the present study, eighty-six Elymus sibiricus accessions, mostly from different parts of Asia, were assayed by gliadin markers based on Acid Polyacrylamide Gel Electrophoresis to ...

This phylogenetic study focuses on a subset of the species in Elymus-specifically, the endemic Asian tetraploids presumed to combine the St genome from Pseudoroegneria with the Y genome from an unknown donor. The primary goals were to (1) determine whether the St and Y genomes are derived from phylogenetically distinct donors; (2) identify the closest relative, and potentially the likely donor,...

In a 2-year field study, we quantified lateral root growth patterns and soil water depletion dynamics in the invasive annual Centaurea solstitialis and two native perennials, Elymus glaucus and Grindelia camporum. Centaurea solstitialis produced lateral roots most actively from early April to mid-June, during the late rosette to spiny seedhead stage while both root growth and water depletion we...

A largely herbarium-based study was undertaken to reassess the status of Elymus athericus (Link) Kerguélen (Sea Couch) and three coastal hybrids E. x drucei (Stace) Stace, laxus (Fr.) Melderis & D.C. McClint. obtusiusculus (Lange) in Scotland. None previous records could be confirmed for country. Verified are detailed listed each relevant vice-county.

the aim of this research was to compare the amounts of existing mineral elements in plant aerial parts, litter and soil ofthree range species (bromus tomentellus, psathyrostachys fragilis, agropyron tauri) in order to investigate the litter effectof species on soil properties of taleghan rangeland. the measured mineral elements include carbon, nitrogen,phosphorous and potassium. after selection...
