Abstract: 5 F2 seedlings of different wheat genotypes were used to investigate the effects of water stress on physiological characters. The wheat seedlings were treated with different water stress. The activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) and the content of free proline and soluble protein were measured in 12, 15 and 18 days. Results showed that these physiological indexes under drought stress were different in 5 wheat seedlings. Testing wheat material 024737 was less affected by drought stress than other four testing wheat materials, which showed that 024737 had high drought resistance.
