摘要: 运用形态学及ITS测序方法,对滇东北地区发现的杉木(Cunninghamia lanceolata)叶斑病病原菌进行鉴定。结果表明,该叶斑病的病原菌形态学特征和分子鉴定结果与Phragmocamarosporium platani相似,初步鉴定为Phragmocamarosporium platani近似种Phragmocamarosporium aff. platani。本研究是该病原菌对杉木危害的初次报道。

关键词: 杉木(Cunninghamia lanceolata), 叶斑病, Phragmocamarosporium, 滇东北地区

Abstract: The pathogen of Cunninghamia lanceolata leaf spot was identified through morphology and ITS sequencing analysis. The results showed that the morphological characteristics and molecular identification of the leaf spot pathogen were similar to Phragmocamarosporium platani, and it was preliminarily identified as Phragmocamarosporium aff. platani. This study was the first report of the Phragmocamarosporium causing damage to Cunninghamia lanceolata.

Key words: Cunninghamia lanceolata, leaf spot, Phragmocamarosporium, northeast Yunnan
