Biochemical Mechanism of Xingxianhuipizhi Resistant to Race 4 of Soybean Cyst Nematode
摘要
Abstract
In order to reveal the biochemical mechanism of Huipizhiheidou resistant to race 4 of Soybean Cyst Nematode, Huipizhiheidou and Jindoull were used as resistant and susceptible varieties. The contents of phenylalanine ammonia lyase (PAL) , superoxide dismutase (SOD), peroxidase (POD) , polyphenoloxidase ( PPO ) , malondialdehyde (MDA) and superoxide radicals(O2- )were measured at 1,4,7,10,13,16,19,22,25,28,31,34,37 d after inoculation with cysts of SCN4. The results showed that the contents of PAL, SOD, POD and PPO in inoculated roots were higher than in non-inoculated roots. Compared to non-inoculated control, the increasing percentage of contents of PAL, SOD, POD, PPO in inoculated roots of Huipizhiheidou were more than those of Jindoul 1, and the fastigium in roots of Huipizhiheidou maintained longer time than in roots of Jind-ou11. After inoculation, contents of MDA and O2- in roots of Jindoul 1 were higher than in roots of control plants. Contents of MDA and O2- in roots of Huipizhiheidou maintained stable for inoculated and non-inoculated plants. These results implied that Huipizhiheidou has higher defense and antioxidant capacity than Jindoull.关键词
