摘要
以几种具有较好应用前景的细胞质雄性不育型小麦为材料 ,对分蘖期小麦叶片中的谷胱甘肽过氧化物酶的活性进行了测定 ,实验结果表明 ,亲本中国春的谷胱甘肽的含量和谷胱甘肽过氧化物酶的比活最高 ,华麦 8号次之 ,细胞质雄性不育小麦均低于保持系中国春与华麦 8号 ,这可能意味着细胞质雄性不育小麦在分蘖期植株体内清除活性氧代谢的能力低于可育品种 ,是小麦以后发育过程花粉走向败育的内在原因之一 .
Using four types(C,G,M,Mt 2) of cytoplasmic male sterile wheat as experiment materials, their maintainer Chinese spring wheat (T.aestivum) as contrast, the activities of glutathione peroxidase(GSHpx) were measured. The results showed that the content of endogenous glutathione and the activities of GSHpx of male sterile material in tillering stage were far lower than Chinese Spring and Huamai No.8,so the ability of eliminating activated form of oxygen is low, which probably associated with the cause of male sterility.
