摘 要：[ Objective] To develop biological control resources of endophytic bacteria in wheat, the bacteria with antagonistic effect against Fusarium graminearum were screened and their antagonistic activity was studied. [ Method] The endophytic bacteria of wheat with antagonistic effect were screened using plate confrontation method; the antagonistic bacteria were identified through physiological and biochemical characteristics and 16S rDNA sequence analysis; the antagonistic spectrum of antagonistic bacteria was studied using plate confrontation method. [ Result] The antagonistic bacterium XY-3 was isolated from wheat leaves, and was identified as Bacillus amyloliquefaciens according to the physiological and biochemical characteristics and 16S rDNA sequence analysis. [ Conclusion] XY-3 had antagonistic effect against four kinds of common pathogenic fungi, presenting broad spectrum antagonistic activity against plant pathogenic fungi.
