| 摘 要： | 以大豆下胚轴切段为材料，研究了质膜氧化还原系统对其伸长生长的作用，结果表明，ＮＡＤＨ氧化酶活性与大豆下胚轴伸长生长相关性极显著（Ｒ＝０．９４，Ｐ＝０．０１），而ＮＡＤＨ－Ｆｅ（ＣＮ）３－６氧化还原酶活性与其相关性不显著。大豆下胚轴伸长生长最快的第一切段，其ＮＡＤＨ氧化酶活性最高。第一切段的伸长生长及ＮＡＤＨ氧化酶对ＩＡＡ均有明显的正负反应。ＩＡＡ促进ＮＡＤＨ氧化酶活性。生长延缓剂Ｂ９对第一切段的伸长生长及ＮＡＤＨ氧化酶活性有抑制作用

| Abstract: | The activities of NADH oxidase and elongation growth of soybean hypocotyl were remarkably interrlated. The segment which had most rapid elongation rate also presented the greatest acitivity of NADH oxidase of soybean hypocotyl. The NADH oxidase and the elongation growth of the first segment had both positive and negative responses to IAA as well. IAA stimulated the activity of NADH oxidase. Growth delayer B 9 inhibited both the NADH oxidase and the elongation growth of soybean hypocotyl. |
