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。
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.
