| 摘 要： | 对黑胫病表现不同抗性的两烟草品种接种黑胫病菌后,对其叶片内超氧化物歧化酶(SOD)、过氧化物酶(CAT)活性及丙二醛(MDA)含量进行测定.结果表明,接种后抗性品种的SOD活性水平与未接种的对照相比差异较小,CAT活性水平低于对照,MDA含量明显高于对照;感病品种的SOD和CAT水平明显高于未接种的对照,MDA含量与对照相比差异较小.接种后抗病品种的SOD和CAT活性明显低于感病品种,而抗病品种的MDA含量却明显高于感病品种.

| Abstract: | After two tobacco varieties with different resistance to black shank were infected with Phytophthora nicotianae, the MDA content and activities of SOD and CAT in tobacco were assayed. The results indicated that the activity of SOD of resistant tobacco variety had little difference compared with that of the control, the activity of CAT of susceptible variety was lower than that of control and the MDA content of resistant variety was higher than that of the control significantly. The~ result also showed that the activities of CAT and SOD of resistant variety were lower than those of susceptible varieties and the MDA content of resistant variety was higher than that of susceptible variety significantly. |
