Abstract
Ten wheat cultivars were screened for salt tolerance at seedling stages under glasshouse conditions. Four levels of salinity i.e., 0.25 (control) 10, 15 and 20 dS m-1 were induced in soil. As the growth of wheat cultivars raised in saline soil substrates indicated that Na+ and Clions in plants increased with the increase in salinity levels, while K+ decreased accordingly. The salt tolerant cultivars (LU26S, Blue Silver and Pirsabak-85) have low Na+ and Clions and high K+ contents. Overall correlation studies between shoot yield of cultivars and Na+ , Cl- , K+ and K+ /Na+ ratio showed the Na+ and Clexclusion and K+ inclusion mechanisms are operating in salt tolerance in wheat crop.
