摘　　要：通过比较试验对板栗内生真菌B2菌株抑制板栗干腐病病原菌D1的特征进行了研究.运用形态学及分子生物学方法对B2菌株的物种进行了鉴定.研究表明,B2菌株菌丝细胞及培养液内均含有抑菌成分,分别对板栗干腐病病原菌菌丝生长及分生孢子萌发有明显抑制作用.该菌株在PDA培养基上菌落白色,绒毛状,不产生色素,是一种担子菌,即phlebia acerina.By comparative examinations,the B2 strains of endophytic fungi of chestnut dry rot pathogen D1 inhibition characteristics were studied. The B2 strains species was identified using morphological and molecular biological methods. The results show that B2 mycelium cells and culture medium contain antifungal ingredients which inhibit the growth of chestnut dry rot pathogen and the spore germination, respectively. This strain on the PDA culture medium, presenting white, villose but without pigment, is one kind of basidiomycetes, namely phlebia acerina.
