摘　　要：水生草本植物芡(Euryale ferox Salisb.)属于睡莲科(Nymphaeaceae)芡属(Euryale),在我国广泛分布,北从黑龙江,南至云南、广东均有种植,多生长在池塘、湖沼中[1]。此外,在印度、巴基斯坦、俄罗斯、朝鲜等国均有分布[2]。因其成熟的果实形如鸡喙,遂有“鸡头米”之称[2]。芡实为植物芡的种子,其味甘、涩,性平,具有益肾固精、补脾止泻、除湿止带等疗效[3],是“药食两用”的天然补品[2]。Leaf neoplasia is a common disease on the leaves of the Euryale ferox,which seriously affects the quality and yield of the product.A new pathogenic fungus causing leaf neoplasia on E.ferox was isolated and purified.Based on morphological characteristics and molecular phylogenetic analysis,the pathogen was identified to be Fereydounia khargensise.To our knowledge,it is the first report of F.khargensise infecting E.ferox in China.The results of this study may provide scientific basis for rapid diagnosis and prevention of leaf neoplasia on E.ferox.
