| 摘 要： | 对优质抗辣椒疫病品种海丰Zt-277、特大汤椒二号F1和感辣椒疫病品种天骄2号进行辣椒疫霉菌接种,测定了辣椒叶片中与抗病性相关的超氧化物歧化酶(SOD)、过氧化物酶(POD)的活性和丙二醛(MDA)的含量变化,结果表明,接种与未接种相比,抗病品种叶片中SOD,POD活性提高幅度要低于感病品种,MDA的含量提高幅度要高于感病品种.但不论辣椒疲霉菌接种与否,抗病品种辣椒叶片中SOD、POD活性高于感病品种;感病品种辣椒叶片中MDA含量高于抗病品种.

| Abstract: | Two resistant cultivars,Haifeng Zt-277(high resistant to Phytophthora blight),Tangjiao No.2(resistant to Phytophthora blight),and a susceptible cultivar Tianjiao No.2(susceptible to Phytophthora blight) were used as materials for Phytophthora capsici inoculation.The activities of enzymes related to disease-resistance including superoxide dismutase(SOD),peroxidase(POD) and the content of malondialdehyde(MDA) in pepper leaves were tested after the inoculation.The results indicated that the activities of SOD a... |
