摘要
用不同低浓度玉米小斑病菌T毒素培养滤液处理玉米叶片,检测玉米叶片中MDA含量变化。结果表明,以1∶40的低浓度T毒素预处理的效果最好。96h的动态测试中,MDA含量较对照平均下降43.8%,从而说明低浓度T毒素培养滤液本身能够作为激发子来诱导玉米的系统获得性抗性。
The paper summarizes the leaves of maize were dealed with the low consistence filtration of Bipolaris maydis race T toxin whose Malondialdenvde content is low. the disposal effect of 1:40 filtration of Bipolaris maydis race T toxin is the best and during 0-96h inspecting, Malondialdenyde content decreased 43.8% in compared with CK. Accordingly, it is accounted that the low consistence filtration of Bipolaris maydis race T toxin may be used as elicitors which enhances the disease resistance of maize.
