摘  要:
研究了墨兰接种炭疽菌后SOD、POD和PAL活性的变化。结果显示:与对照相比,接种后36h之前PAL活性变化不大,36h后活性开始上升,84h时达到最高;POD在接种后12和60h出现两个活性高峰,且第1峰大于第2峰;SOD在接种后12h达到最高,之后下降。

摘  要:
The occurrence of diseases and changes in activities of the three protective enzymes,phenylalanine ammonialyase(PAL)、peroxidase(POD)and superoxide dismutase(SOD)in leaves of Cymbidium sinense, were studied after inoculating Colletotrichum gloeosporioides.The results showed that the activities of PAL increased significantly after 36 h inoculation with C.gloeosporioide, and reached the highest activities at 84 h.POD activities appeared two peaks at 12 h and 60 h, respectively,after inoculation.The first peak surpassed the second peak.SOD activities rose quickly after inoculation with C.gloeosporioide,and reached the highest level at 12 h,then fell.The increase in the activities of PAL,POD and SOD showed that these three enzymes play an important role in resisting the infection of C.gloeosporioide.
