| 摘 要： | 以分离自4种寄主的5株多主棒孢菌株接种橡胶树叶片,均得到成功侵染。并按时间顺序测定了来自不同寄主的多主棒孢侵染橡胶树叶片后,细胞防御系统相关的4种酶活性的变化。结果表明,接种来自不同寄主的多主棒孢后,对橡胶树叶片4种防御酶活性的影响不同。其中分离自橡胶树的HCCGD01和HCCHN42两个菌株侵染后,橡胶树叶片组织4种防御酶活性变化最大,均有明显增强;来自木薯的MaCCGD02侵染橡胶树叶片后,酶活性变化次之;分离自番木瓜的CpCCYN01和黄瓜的PaCCSD04多主棒孢菌株侵染后,除PAL外,β-1,3-葡聚糖酶、POD、PPO活性变化很小。

| Abstract: | The influence of Corynespora cassiicola isolated from 4 different hosts on defensive enzymes activities（β-1,3-glucanase,POD,PAL,PPO） in the leaves of Hevea brasiliensis was studied in this paper.The results showed that the changes of 4 kinds of defensive enzymes activities in the leaves of Hevea brasiliensis were different with inoculated Corynespora cassiicola isolated from different hosts.The activities of these defensive enzymes quickly enhanced after inoculation by the pathogens（HCCGD01 and HCCHN42） isolated from Hevea brasiliensis,and slower increase in leaves inoculated by MaCCGD02 isolated from cassava.However the activities of β-1,3-glucanase,POD,PPO almost unchanged when the leaves were infected by PaCCSD04 from cucumber and CpCCYN01 from papaya. |
