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