杨树叶锈病研究

Research on Poplar Leaf Rust

松杨栅锈菌(Melampsora larici-populina)导致的杨树叶锈病是杨树病害中分布最广、危害最大的一种病害,它造成杨树林的材积损失和材质下降,严重制约着杨树商品林和生态林的发展。该文从病原菌的分布和寄主种类、病原菌生理分化、寄主抗锈性及分子标记、防治措施等几方面介绍了杨树叶锈病的研究。

Leaf rust caused by Melampsora larici-populina was the most widespread and serious disease of poplars,led to timber volume loss and wood quality reduction,and badly restricted the development of commodity and ecology forest.Researching on Melampsora larici-populina was introduced in this paper from aspects of distribution and host varieties of plant pathogenic fungi,physiological differentiation,host poplar resistance and molecular markers,control measures and so on.
