摘　　要：青杨叶锈病在我国的杨树锈菌病害中最为严重,分布广、寄主种类多、造成的损失大,使杨树干重减轻29%~32%,材积损失31%~42%,生长量损失65%,严重影响杨树用材林及防护林的发展。国内学者对青杨叶锈病进行了大量研究,但报道较为分散。本文比较全面综述了该病原菌转主寄生长循环型生活史中各发育阶段的形态特征、引起的病害症状、发病规律、分布与危害,着重介绍了防治策略。最后提出了建议,促使我们研究更科学、更合适的青杨叶锈病防治方法,促进我国森林健康和杨树生产的发展。Poplar leaf rust Melampsora larics-populina is the most severe poplar rust disease in China.It is widely distributed with quite a few host species;it causes great losses,reducing the weight of poplar trunk by 29%~32%,the volume by 31%~42%,and the growth by 65%,seriously affecting the development of timber forest and shelter forest in China.The scholars in China have done a lot of research on this leaf rust,but the reports are relatively scattered.This paper focuses,in a more comprehensive way,on the morphological characteristics in each development stage in its life cycle,disease regularity,distribution and harm caused,with emphasis on the prevention and control strategies.Some suggestions are made concerning more scientifi c and more suitable methods of preventing and controlling the leaf rusts for the healthy growth of the forestry and poplar production in China.
