The aim of this research was to investigate the effect of index species, Astragalusammodendron on the associated plants of Agropyron tauri and Bromus tomentellus fromdifferent aspects in Shazand rangeland in southwest of Markazi province. The effects ofspecies density and distribution pattern and then index species on the soil properties werestudied. Based on the randomized – systematic method,...

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...

Two species of Agropyron grass differed strikingly in their capacity to compete for phosphate in soil interspaces shared with a common competitor, the sagebrush Artemisia tridentata. Of the total phosphorus-32 and -33 absorbed by Artemisia, 86 percent was from the interspace shared with Agropyron spicatum and only 14 percent from that shared with Agropyron desertorum. Actively absorbing mycorrh...

To help in the clarification of the taxonomic status of Elymus L. and related genera Agropyron Gaertn., Leymus Hochst., Hordelymus (Jess.) Harz, and Brachypodium P.Beauv., the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied. ITS data of 64 Triticeae accessions including 40 Elymus, 12 Agropyron, 7 Leymus, and 4 Hordelymus, and 1 Brachypodiu...
