The drought-resistant cultivars including Baihong 3, Baihong 4, Baihong 5 and Jihong 352 as materials and PEG with different concentrations(5%, 10%, 20%) simulating water stress treatment in seedling stage of adzuki beans were used in this study. The function leaf on the third, sixth and ninth day was picked to determine drought resistance physiological indicators. The results showed that the indicators that could be used to identify the drought-resistance of adzuki bean were the SOD activity of 5% PEG trea...
