香蕉与枯萎病菌互作中3种酚类物质的含量变化研究

对抗枯萎病和感枯萎病2个香蕉品种进行人工接种枯萎病菌4号生理小种不同时间后,采用高效液相色谱测定法对2者根系内3种酚类物质含量变化进行分析.结果表明,接菌后,抗病和感病香蕉品种根系内的水杨酸、阿魏酸及绿原酸含量均比接种前高,但抗病品种的增加量比感病品种的大,且净增加量达到峰值的时间快；抗病品种内源水杨酸和绿原酸含量明显...

Changes of Three Phenol Compounds Content during the Interaction of Banana and Fusarium oxysporum f.sp. cubense

In this study, high performance liquid chromatographic method was used to analyze the changes of three phenols content in the roots of two different resistant banana cultivars at different period with artificial inoculation of Fusarium oxysporum f.sp. cubense. The results showed that the contents of salicylic acid, ferulic acid and chlorogenic acid in the roots of the two treated groups were all higher than that in the control and the increasing range in the resistant variety was higher and reached the peak faster than that in the susceptible variety. At the same time, the contents of salicylic acid and chlorogenic acid in the resistant variety were obviously higher than that in the susceptible variety, but there were no significant differences of ferulic acid contents in two cultivars.
