四川省袋栽毛木耳镰刀菌病害研究简报

Study of Fusarium Pathogen on Auricular ia poly tricha Cultivated with Plastic Bag in Sichuan Province

镰刀菌病害是四川省袋栽毛木耳的主要病害,从各主产地采集的16个耳袋样品中分离到20个菌株,鉴定结果显示它们同属一种镰刀菌,即茄腐皮镰孢霉[Fusarium solani（Mart.）Sacc.].本文描述了该病菌的培养特征、形态特性、症状及发病规律。研究表明,毛木耳是镰刀菌在食用菌中的一个新寄主。

Fusarium pathogens were the most important pathogens infecting Auricularia polytricha (Mont.) Sacc. cultivated with plastic bags in Sichuan Province. Twenty Fusarium isolates were obtained in 16 samples of plastic-bag-cultivated hairy wood ear collected from different parts of Sichuan Province. Identified from these isolates, it was found that this kind of Fusarium pathogen belonged to Fusarium solani (Mart.) Sacc.. Its culture features, morphological characteristics, infection symptoms and pathogenetic regularity were described in this paper. The investigation results indicated that Auricularia polytricha was a new edible mushroom host of Fusarium pathogens.
