葡萄抵御霜霉病菌侵染的生理生化防卫反应研究
Study on Physiological and Biochemical Defense Responses of Grape Against Infection of Plasmopara viticola
摘要
Abstract
In order to provide theoretical references for grape resistance breeding against Plasmopara viticola,field investigation and indoor inoculation were used to detect the grape resistance to Plasmopara viticola.The changes of SOD,POD and CAT activities and SA,H2O2 and JA contents in leaves of different resistant varieties were determined after inoculation with Plasmopara viticola.The effects on grape resistance to Plasmopara viticola were observed after spraying SA,H2O2 and JA to clarify the physiological and biochemical defense responses of grape against the infection of Plasmopara viticola.The results showed that,compared with the susceptible varieties,the activities of POD and CAT were rapidly increased after inoculation.The contents of SA and H2O2 in different varieties increased obviously after inoculation compared with the control,and the resistant varieties showed earlier and higher formation amounts.JA content increased in different varieties,but there were no significant differences between cultivars.SA,JA and H2O2 were helpful to enhance the resistance of grape to Plasmopara viticola.SA enhanced the resistance obviously and the resistance was enhanced by 44.87％.关键词
