Abstract:
Three different resistant varieties of L.indica,‘Zikang No.1’‘Zikang No.2’‘Sihaishengping’were used as materials,and the pathogen was inoculated with spore suspension of powdery mildew.After inoculation,the contents of soluble protein,MDA and activity of SOD in leaves were measured and the relationship between the resistance to powdery mildew and contents of soluble protein,MDA and activity of SOD of leaves were analyzed.The results showed that the activity of SOD in resistant cultivars and immune cultivars was higher than that of susceptible cultivars,and the SOD repair of resistant varieties and immune varieties were faster than susceptible varieties.The content of MDA in susceptible cultivars increased,and the content and variation trend of resistant varieties and immunized varieties were similar,the change was small and always lower than susceptible varieties.The content of soluble protein was similar to that of susceptible cultivars,and the change of soluble protein content was the same,which showed the trend of rising and then decreasing.
