摘要
木霉菌是重要的植物病害生防菌。通过对峙培养法,测定了哈茨木霉(Trichoderma harzianum)菌株NF9和绿木霉(Trichoderma virens)菌株TY对3种土传植物病原真菌的体外拮抗作用。结果表明,这2株木霉菌对黄瓜枯萎病菌、西瓜枯萎病菌及茄子白绢病菌均具有一定的拮抗作用,不同木霉菌株间拮抗效果存在差异,哈茨木霉菌株NF9优于绿木霉菌株TY。
The fungous Trichoderma is an important microorganism in the biological control of plant diseases. The antago- nism of Trichoderma harzianum NF9 and Trichoderma virens TY against three soil-borne plant fungous pathogens, Fusarium oxysporum Schl. f. sp. cucumerin Owen, Sclerotium rolfsii and Fusarium oxysporum Schl. f. sp. niveum, were tested in vitro by dual-culture. The result showed that two Trichoderma isolates had antagonism effect on the tested pathogens, and Trichoderma harzianum NF9 was better than Trichoderma virens TY in antagonism effect.
