| 摘 要： | 正波叶大黄Rheum rhabarbarum L.隶属于蓼科Polygonaceae大黄属Rheum,是一种重要的药用植物。白粉病多发生在波叶大黄的叶部,会影响其光合作用进而降低其药用价值。据笔者统计,目前关于蓼白粉菌Erysiphe polygoni DC.在世界范围内的报道有很多~([1~9]),但其中关于蓼科Polygonaceae波叶大黄白粉病病原菌的报道较少,目前仅有1个 |

| Abstract: | The powdery mildew is rarely reported on Rheum rhabarbarum (Polygonaceae). In 2003, Erysiphe polygoni was the first mentioned on R. rhabarbarum in China without morphological and molecular data. In August 2015, Powdery mildew on R. rhabarbarum in the medicinal garden was found at Jilin Agricultural University in Changchun(43.61°N,125.41°E), China. The isolate from the sample was identified as E. polygoni based on its morphological characters and internal transcribed spacer (ITS) sequence, which is firstly characterized by both biological and molecular features. Meanwhile, E.polygoni as a new pathogen on R.rhabarbarum is firstly reported in Jilin province. |
