This study was conducted to evaluate the response of germination, seedling growth and antioxidant enzymes activity 15 chickpea cultivars to salinity at the University of South Korea Dankook a factorial experiment in a randomized complete block design with four replications. The treatments include chickpea cultivars and, salinity levels of water (water with electrical conductivity 0.7 dS/m as a witness and as salinity salinity level 5 dS/m), respectively. The results showed that salt stress decreased seed germination and enzyme activity of alpha amylase was on the soil surface. Salinity reduced leaf dry weight and photosynthesis chickpea varieties of chickpea cultivars, but increased respiration rate. Cultivars of MCC873, MCC10, MCC78, MCC870, MCC537 and MCC392 highest leaf dry weight and photosynthesis, respectively, and at the same time cultivars MCC776 and MCC552 with 6.10 g dry weight and plant 0.63 from a low dry weight respectively. Activity of catalase and glutathione peroxidase guaiacol was increased by salinity. The highest concentrations of malondialdehyde, indicating that the degradation of plant cell membranes in the cultivars of MCC759, MCC361 and MCC101 of 0.95, 0.94 and 0.92 nmol per gram fresh weight of seedlings were observed. MCC392 while the lowest concentrations of malondialdehyde was under salt stress. The results showed that under salinity stress cultivars of MCC 873, MCC 10, MCC78, MCC870, MCC537 and MCC392 with enzyme activity were more antioxidants had higher rates of photosynthesis and plant weight.
