我国杨树溃疡病研究进展

杨树溃疡病主要由真菌侵染所致,该真菌是一类世界性分布的真菌,寄主范围十分广泛,可危害多种林木和果树的树干及果实,引起枯枝、溃疡、流胶和果腐等。另外,还可以引起根腐,导致整株树的枯死。发生病害的林木,用材林材性降低,经济林产量降低,造成严重危害和经济损失。文中对其病害分布、致病机理、抗病机制以及抗病育种等进行了综述。

The Advance of Canker Disease-Resistance Breeding in Poplar

Poplar canker is mostly caused by fungi.These kind of fungi distributes world wide,parasites wide-ranging hosts,and harms the branches and fruits of many kinds of forest and fruit trees.It can cause the branches die, canker disease,glue flow,and fruit rot,et al.It also can cause root rot and lead to the tree dead.When the forest tree infected by these fungi,the wood quality of timber forest was decreased,the production of economic forest was reduced,and economy was suffered heavy loss.This paper reviewed the distribution,pathopoiesis mechanism, disease-resistant mechanism, and disease-resistant breeding of Poplar canker
