Effect and Identification of Volatile Compounds from Trichoderma Against Fusarium oxysporum
摘要
Abstract
The inhibitory effects and compounds of volatile substances from 11 Trichoderma strains against Fusarium oxysporum were analyzed.The results showed that there were significant differences between the contents and types of volatile substances of different Trichoderma species.11 species of Trichoderma were detected 257 kinds of volatile substances,Which can be detected hexamethyl cyclotrisiloxane,octamethyl cyclotetrasiloxane two compounds;When the cluster analysis in the correlation coefficient distance was 19 hours,the 11 Trichoderma could be divided into 3 components.The results showed that ACCC33104 had the highest total score of 30 volatile substances,and the difference of the volatile components of T.viride was different from that of its antagonistic effect on F.oxysporum.The effect of bacteria have a certain relevance.The results showed that Trichoderma had inhibitory effect on F.oxysporum.关键词
