| 摘 要： | <正>0 引言近年来,在草莓‘甜查理’等品种上出现一种新病害,发病初期表现为叶片红色,后期全株萎蔫。2019年课题组对采自江苏省徐州市贾汪区的草莓红叶病样进行分离,初步鉴定为类拟盘多毛孢真菌。经与国内已报道危害草莓的类拟盘多毛孢真菌Neopestalotiopsis clavispora1-5]比较,结果发现课题组分离的菌株与N. clavispora在系统树上明显区分,推测待测菌株属于危害草莓的新纪录种群,需开展深入鉴定工作。1

| Abstract: | In order to identify the pathogen of strawberry red leaf root rot in Jiawang District of Xuzhou City, Jiangsu Province, we conducted experiments on isolation and purification, pathogenicity determination, morphological identification and molecular phylogenetic analysis. The results showed that Neopestalotiopsis roase was the pathogen. It is the first report of N. roase infecting strawberry in China. |
