摘要
"白毛菌病"是近年来东北地区木耳栽培中一种常见病害。其病原菌在盛夏伏天侵染木耳子实体,在木耳耳片腹面生长一层白色网状霉层,对木耳生长及商品形态造成严重危害。从黑龙江省尚志地区染病耳片上分离得到两株病原菌,经对它们进行形态学特征观察、rDNA ITS序列分析和致病性测定,证明这两株病菌为尖孢镰孢和厚垣镰孢,二者均对栽培木耳具有致病性。
The white mildew disease on Auricularia auricula-judae was epidemic in recent years in Northeast China.The pathogenic fungi formed a layer of white pull-mesh mycelium on the ventral side of the fruiting body of A.auricula-judae in hot summer.The fungi significantly reduce the yield as well as the quality of the fruiting bodies.In this study,two fungal strains were isolated from the infected fruiting bodies cultivated in Shangzhi of Heilongjiang Province.They were identified as Fusarium oxysporum and Fusarium chlamydosporum.Both of them are pathogenic to the fruiting body of A.auricula-judae.
