摘要:
以抗旱的大豆品种豫豆24、对照品种周豆11为试验材料，以聚乙二醇(PEG)模拟干旱胁迫条件，探讨了不同干旱胁迫下抗坏血酸(AsA)和还原型谷胱甘肽(GSH)含量的动态变化及其在清除活性氧过程中的作用。结果表明，干旱胁迫增加了2个大豆品种中AsA和GSH含量，两者均在10% PEG处理48 h时达到最大值，抗旱品种豫豆24比对照品种周豆11增加幅度大，表明AsA和GSH可能参与了大豆的抗旱响应；干旱胁迫显著增加了2个大豆品种中过氧化氢(H2O2)和超氧阴离子 O-2[KG-*2]· [KG-*3]含量，抗旱品种豫豆24的增幅低于对照品种周豆11；AsA和GSH抑制剂处理进一步增加了干旱胁迫下大豆根中活性氧和丙二醛含量。表明干旱胁迫下AsA和GSH在清除活性氧从而增强大豆抗旱性中起着重要的作用。
