Abstract

In order to study of salt tolerance of Iranian barley (Hordeum vulgare L.) genotypes in seedling growth stages, this study were conducted in the Agricultural Sciences Laboratory and Greenhouse of the Islamic Azad University of Miyaneh branch during summer 2006. This study was carried out in factorial experiment design on the basis of completely randomized design in 3 replications. Salinity treatments involved in 5 levels: S0=control, S1=37.5, S2=75, S3=150, S4=225 mmol/l from calcium chloride and sodium chloride with 2:1 (Ca:Na ratio) and another factor was genotype involved 12 varieties from current barley varieties in Iran. The effects of salinity treatments were studied by sampling on dry weight of shoot, roots, shoot length and fresh weight of root and shoot as well as leaf area. There were a significant differences amongst the genotype × stress interaction for all characters. The results showed that leaf area, dry weight of shoot, dry weight of root, shoot length, fresh weight of steam and fresh weight of root were decreased in all 12 barley varieties with increasing in salinity level. However varieties of SINA, GORGAN and DASHT showed the best response at all salinity levels.
