本文对杨树叶锈病在皖北地区的发病特点、病原菌形态进行了初步研究，分析了锈病发生与品种、林地管理、降水和湿度等因素的关系，结合现代分子生物学分类技术将病原菌鉴定为落叶松-杨栅锈菌。研究表明，杨树叶锈病在皖北地区一年只有秋季一次高发期；锈病的发生与多种因素关系密切；在无转主寄主的情况下可以连年危害。

In this paper a preliminary study was made on the characteristics of the poplar leaf rust and its pathogen morphology in northern Anhui Province. The relationship between the rust occurrence and factors including the poplar varieties, forestland management, precipitation and humidity was analyzed. The pathogen was identified as Melampsora larici-populina, with m odern m olecular biology classification technologies. The study showed that the poplar leaf rust has only one high-incidence period in autumn in northern Anhui, its occurrence is closely related with many factors and the disease can harm poplar leaves in consecutive years in case of no alternate hosts.
