摘　　要：目的:掌握庐山园林植物白粉病发生的现状,明确白粉病病原菌种类。方法:采用踏查法对庐山园林植物白粉病进行调查,通过形态观察和分子系统发育分析相结合鉴定园林植物白粉病病原菌。结果:白粉病主要危害庐山青冈(Quercus glauca)、二球悬铃木(Platanus acerifolia)、野芝麻(Lamium barbatum)等9科19属19种植物,共鉴定出白粉病病原菌6属11种,其中9种白粉病病原菌为江西省园林植物新记录种,分别是Erysiphe platani,Erysiphe quercicola,Golovinomyces artemisiae,Golovinomyces asterum var.solidaginis,Golovinomyces bolayi,Neoerysiphe galeopsidis,Podosphaera macularis,Podosphaera xanthii,Sawadaea tulasnei。此外,阿拉伯婆婆纳(Veronica persica)为Golovinomyces bolayi的中国新记录寄主。结论:研究结果为进一步研究庐山园林植物白粉病病原真菌多样性提供理论依据,对防治庐山园林植物白粉病具有积极意义。Objective:To investigate the occurrence status of powdery mildew on landscape plants in Lushan,and to clarify their pathogen species.Methods:The powdery mildew on landscape plants was investigated using the method of on-site surveys,and the pathogen causing powdery mildew on landscape plants was identified by morphological observation and molecular phylogenetic analysis.Results:The study showed that powdery mildew mainly damaged 19 species belonging to 19 genera in 9 families,such as Quercus glauca,Platanus acerifolia and Lamium barbatum.A total of 11 species from 6 genera of powdery mildew pathogens were identified,of which 9 species were newly recorded of landscape plants in Jiangxi Province.They were Erysiphe platani,Erysiphe quercicola,Golovinomyces artemisiae,Golovinomyces asterum var.solidaginis,Golovinomyces bolayi,Neoerysiphe galeopsidis,Podosphaera macularis,Podosphaera xanthii,Sawadaea tulasnei.In addition,Veronica persica was identified as a new host of Golovinomyces bolayi in China.Conclusion:The results provide a theoretical basis for further research on the diversity on pathogen fungi of powdery mildew on landscape plants in Lushan,and have positive significance for the prevention and control of powdery mildew on Lushan landscape plants.
