Comparison of Antagonistic Effects of Four Trichoderma Strains
摘要
Abstract
Using confrontation test,detection of volatile and non-volatile inhibitory substances and assay of chitinase activity as well as inoculation on cucumber seedlings,we compared the potential biocontrol activity of four selected Trichoderma strains.Among them,strain YZ1303 showed the strongest antagonistic activity against Fusarium oxysporum f.sp.cucumerinum in confrontation test,but the lowest chitinase activity in in-vitro detection.The non-volatile substances released from strain SH2303 exhibited the highest inhibition rate of 41.33% against pathogen growth,and the strain also had the highest control efficacy against cucumber Fusarium wilt.Comparatively,strain HF3407 was identified in vitro with higher activity of chitinase and higher production of inhibitory volatile substances,and also proven in vivo to be good in the control of cucumber Fusarium wilt.Taken together,establishment of a comprehensive evaluation system is of great importance to the highly effective screening of antagonistic Trichoderma strains.关键词
