The Effect of Salinity Stress on Seed Germination of Agropyron elongatum

Successful seedling establishment depends on the frequen-cy and the amount of precipitation as well as on the ability of the seed species to germinate and grow while soil mois-ture and osmotic potentials decrease. Germination and seedling characteristics are the most valuable criteria for selecting salt tolerance in plants. Salinity stress can reduce seed germination through osmotic effects (Jamil et al. 2006). Agropyron is a perennial grass genus with 19 dif-ferent species reported. This genus has wide adaptation and can be grown in different climates. The objective of this study was to evaluate the impact of salinity stress on the germination of Agropyron elongatum seed under laboratory conditions.
