Abstract

To study the effect of salinity on germination and threshold of barley germplasms two experiments carried out as a factorial arrangement based on completely randomized designin greenhouse and laboratory condition. In the first experiment 23 barley germplasms (17 wild and 6 improved barely cultivars) were investigated for germination index with four treatments of salinity (0, 100, 200 and 300 Mm NA+Cl) in three replications and in the second experiment the THRESHOLD SALINITY of 7 germplasms that selected from the first experiment were analyzed in five treatments (1.3, 5, 10, 15 and 20 ds.m-1) with four replications. At the end of the first experiment, following factors were measured: germination percent, root length, shoot length, root fresh weight, root dry weight, shoot fresh weight, shoot dry weight, NA++ root content, K++ root content, NA++ shoot content, K++shoot content also THRESHOLD SALINITY, shoot length, dry and fresh weight, NA++and K++content was measured in the second experiment. The result showed that increased salt concentrations caused decrease final germination percentage (P≤0.05). Some of germplasms showed high tolerance to salinity. The RELATIVE YIELD of dry weight indicated that H.vulgare, var. Afzal with 25.24 ds.m-1andH.murinum (Ilam) with 16.65 ds.m-1 which had the maximum and minimum EC50 value respectively between these germplasms. In this experiment the NA+tive cultivar had a highest tolerance with compared to the other cultivars that is likely contain genes for resistance to salt stress.
