摘要
Effect of root extracts from various rootstocks, and different concentrations were studied on the spore germination and mycelium growth of eggplant verticillium wilt. The root extracts of grafted eggplants inhibited the spore germination and mycelium growth of verticillium wilt. The inhibitory effects Were enhanced with increasing concentration of root extracts. The amino acids and main phenolic acids showed that, aspartic acid and threonine were present only in grafted treatments. The contents of alanine, methionine, isoleucine and tyrosine were higher in the grafted plants, while, those of glycine, phenylalanine and histidine were higher in non-grafted plants. Main phenolic acids present in root extracts were vanillin, cinnamic acids and benzoic acids. There were differences in quantity and composition of amino acids and phenolic acids between root extracts of grafted and non-grafted eggplants at some extent, which might be one of the reasons for resistance to the verticillium wilt.
