丛枝菌根真菌提高黄瓜幼苗抗立枯病作用研究
Study of Tolerance Effects on Blight of Cucumber Seedlings Induced by Arbuscular Mycorrhizal Fungi
摘要
Abstract
The cucumber strain Zhongnong 16 were used to screen the effect of arbuscular mycorrhizal fungi on seedling blight of cucumber in solar greenhouse , and related physiological and biochemistry changes were studied . The result indicated that when cucumber seedlings inoculated with mycorrhizal fungi it can significantly enhance the ability of cucumber resistance .After inoculated rhizoctonia solani incidence rates of AM cucumber seedlings and non A-M cucumber seedlings were 16 .5% and 52 .0%.The mean disease index of cucumber seedling inoculated with AMF was 78.5%lower than that of the control respectively ,moreover,there were most obvious the differences between the treatments and the control .Before disease occurrence the sysbiosis of AMF and host plant had formed and the relevant mechanisms of disease resistance had been started .The inoculation of AMF enhanced plant grewth and improved the activity of protect enzyme .During disease occurred AMF and pathogens compete with each other . AMF inhibited the infection of bacteria against host plant .It manifested on activity of Reactive-oxygen-scavenging Enzymes insensitive to the inoculation of pathogens .Degree of membrane lipids peroxidation depressed the damage of cell membrane was smaller .关键词
