Abstract:

To find out the effects of drought stress on the physiological and biochemical characteristics of different sesame, high drought-resistant material Liulin 3 and drought-sensitive material g76 were used as experimental materials to induce drought stress in the seedling stage. The results showed that with the extension of drought stress time, the proline contents of the two sesame materials showed an upward trend. Among them, the proline content of g76 increased gently after drought treatment, while the proline content of Liulin 3 increased rapidly at three days of drought treatment and then increased steadily. The malondialdehyde (MDA) contents of the two sesame materials showed a trend of gradual increase with the extension of drought time, the content of MDA of high drought-resistant material increased slowly, while the content of MDA of drought-sensitive material increased rapidly at three days of drought treatment and then increased steadily. The activities of superoxide dismutase (SOD) of the two sesame materials continued to increase during the drought treatment. The SOD activity of Liulin 3 increased rapidly at three days of drought treatment and then increased steadily, while the SOD activity of g76 increased rapidly at six days of drought treatment and then increased steadily. The catalase activities of the two sesame materials showed an increasing trend first and then decreasing during drought treatment. The g76 reached the maximum value at six days of drought treatment and Liulin 3 reached the maximum value at nine days of drought treatment.
