Homand Absard Rangeland Research Station is located 70 km northeast of tehran and 15 km southeast of Damavand with an altitude of 1972 m a.s.l., an average annual rainfall of 333 mm,  and a cold semi-steppe climate. In order to compare  the seed production of Vicia villosa under different cultivation seasons and methods, the seeds were initially collected from natural habitats similar to the m...

range forage of vicia variabilis, astragalus spp., medicago sativa, prangos uloptera and sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in chaharmahal and bakhtiari province, iran. samples were analyzed for the determination of crude protein (cp%), ether extract (ee), crude fiber (cf), total ash, neutral detergent fiber (ndf), acid detergen...

Frankia sp., the actinomycetous endophyte in nitrogen-fixing actinorhizal nodules, may differentiate two forms from its hyphae: vesicles and sporangia. In root nodules of Comptonia peregrina (L.) Coult. and Myrica gale L., sporangia may be either absent or present. Nitrogenase activity and symbiotic efficiency were contrasted in spore(+) and spore(-) nodules of these two host genera. Seedlings ...

Haemolytic favism is a severe, acute anaemia which occurs in glucose-6-phosphate dehydrogenase deficient individuals, usually following the ingestion of Vicia faba seeds. Current interest is focused on the nature of the active substances of Vicia faba and on the causes of the varying susceptibility among G6PD-deficient individuals to episodes of severe haemolysis. The results of experiments in ...
