ABSTRACT:Salinity is one of the most widespread environmental stresses heavily on the crop affects fertility. In order to study the effect of salinity on germination and seedling growth of three barley cultivars, an experiment was conducted as factorial with completely randomized design with three replications in lab of seed department. Experimental factors including: cultivar (Sahra, Mahor and Nimrooz ) and salinity (0, 3, 6, 9, 12 and 15 ds/m). The results showed that cultivar had significant affect on germination percentage, germination rate, index of germination, primary root length and root wet weight Sahra cultivar had the highest percentage of germination (96%), seed of germination (6 days), index of germination (75), primary root length (8.8 cm) and root wet weight (38 g) other then cultivars. Salinity had significant affect on percentage of germination, seed of germination, index of germination, primary root length and root wet weight. The highest and lowest percentage of germination, seed of germination, index of germination, primary root length and root wet weight were obtained from check treatment and 15 ds/m respectively. But between 9 and 12 ds/m had not significant difference on percentage of germination percentage, germination rate and index of germination.
