【摘要】 将木霉菌株Ｔ８８与７种常见的林果病原真菌进行平板对峙培养及显微观察，结果表明木霉菌株Ｔ８８对立枯丝核菌Ｒｈｉｚｏｃｔｏｎｉａｓｏｌａｎｉ等供试的７种病原真菌都有明显的拮抗作用，可观察到Ｔ８８对病原菌菌丝的缠绕、使细胞质变稀薄、菌丝消解或穿透等现象，以及对齐整小核菌Ｓｃｌｅｒｏｔｉｕｍｒｏｌｆｓｉ的菌核的重寄生作用，使其发生腐烂，并抑制了白绢病菌菌核的萌发。更多还原

【Abstract】 Trichoderma T88 showed obvious antagonism to 7 species of plant pathogenic fungi,including Rhizoctonia solani,Alternaria sp., Armillariella mellea, Fusarium sp., Sclerotium rolfsii, Cytospora chrysosperma and ]Valsa mali in dual culture. In vitro, the phenomena that hyphae of the pathogenic fungi were coiled, lysed and penetrated and their cytoplasma became thining were observed under microscope. As result of hyperparasitism to the sclerotinia of sclerotium rolfsii, the pathogenic sclerotinia become rot and their germination was inhibited.更多还原
