木菠萝果腐病中一种新病原菌的分离与鉴定

摘要

One isolate Bl was obtained from the samples of fruit rot disease of Artocarpus heterophyllus Lam. Collected from Dongsheng Farm in Hainan. The pathogenicity of the isolate was confirmed based on Koch's postulates. The pathogen was identified as Cylindrocladium sp. Based on the morphological characteristics and the ITS sequence of ribosome DNA. This is the first report that Cylindrocladium sp. Can cause fruit rot disease of Artocarpus heterophyllus Lam-%在海南省东升农场发现一种新的木菠萝果腐病,采用常规组织分离法获得一个菌株B1,经柯赫氏法则验证确定其为该病的病原菌.通过形态学鉴定和rDNA-ITS序列分析,结果表明:该病原菌为帚梗柱孢霉(Cylindrocladium sp.)；帚梗柱孢霉(Cylindrocladium sp.)引起的木菠萝果腐病为首次报道.
