摘要:
为探索硒浸种对大豆种子萌发的生理生化效应，研究了不同浓度的硒溶液浸种后，大豆种子的萌发率和发芽指数的变化及大豆种子萌发期SOD、POD和PPO活性的变化。结果表明:适当浓度的硒浸种，可以提高大豆种子的萌发率、发芽指数、大豆种子萌发期SOD、POD和PPO活性。硒浸种处理大豆的最适宜浓度为0.05 mg·L-1。当硒浓度大于0.05 mg·L-1时大豆的萌发生长受到抑制，酶活性降低。
Abstract:
In order to study the physiological and biochemical effects of Se soaking on soybean seed germination. Germination rate, germination index and activities of SOD, POD and PPO of soybean seed with different Se concentrations were studied.The results showed that suitable Se concentration seed soaking could raise the germination rate and index, and also enhance the activities of SOD, POD and PPO. The most suitable Se concentration of seed soaking was 0.05 mg·L-1.When Se concentration was higher than 0.05 mg·L-1, soybean seed germination was inhibited and the three enzymes activities decreased.
