| 摘 要： | 2013年在内蒙古赤峰市喀喇沁旗发现桔梗匍柄霉叶斑病,该病害在2014-2017年均再次发生。采用单孢分离法在病叶上得到病原菌,于PCA培养基上培养后,在光学显微镜下观察记录病原菌形态学特征。同时将病原菌的rDNA ITS、gpd和EF-1α的PCR产物测序后做BLAST分析。结果表明该菌与桔梗匍柄霉Stemphylium platycodontis基本一致。这是国内桔梗匍柄霉叶斑病的首次详细报道。

| Abstract: | A new leaf spot disease on bellflower was discovered in Harqin, Chifeng, Inner Mongolia in 2013, and it spread continuously in 2014-2017. Morphological observation and rDNA ITS, gpd and EF-1α sequence analyses proved that the fungus was similar to Stemphylium platycodontis. This is the first report of Stemphylium on bellflower in China. |
