【摘要】 以三个抗灰斑病和三个感病品系为试材,分析了不同抗性大豆品系感染灰斑病后叶片中过氧化作用的变化。结果表明:1.大豆感染灰斑病后超氧物歧化酶活性均有所增加,且有感病品系超氧物歧化酶活性高于抗病品系的趋势;2.大豆感染灰斑病后过氧化物酶活性也有所增加,感病后感病品系的过氧化物酶活性明显高于抗病品系的;3.大豆感染灰斑病后所有品系的抗坏血酸含量均降低,感病品系的抗坏血酸含量高于抗病品系的;4.大豆感染灰斑病后,感病品系的叶绿素含量高于抗病品系的。更多还原

【Abstract】 Three resistant lines and three susceptable lines were used in this experiment. The results showed that;1.SOD activity of all lines increased when infected by Cercospoora Sojina Hara , and the SOD activity of susceptable lines was higher than that of resistant lines. 2. the POD activity increased for all lines when infected, but the pod activity of susceptable lines was higher than that of resistant lines. 3. The ascorbic acid contents of susceptable lines was higher than that of resistant lines either or not infected, and decreased for all lines infected by Cercospoora Sojina Hara.更多还原
