中国杨树上的栅锈菌

杨树锈病是一类重要的林木病害，因其病原菌的种类较多，且病害症状及病原形态上的差异不够明显，导致栅锈菌种类鉴定混乱和病原准确认知困难。在分析国内外栅锈菌分类学历史与现状的基础上，从杨树栅锈菌的形态学及系统学2个方面对中国杨树上的栅锈菌种类进行整理，并详细阐述8种栅锈菌在寄主及转主寄主、繁殖体及孢子形态上的差异，编制中国杨树栅锈菌的分种检索表，以期加深对该病原菌的科学认知。

Eight Melampsora Species Infected in Poplars in China

Poplar rust is one of the most important diseases infected in Populus species in China.However,it is hard to accurately identify the pathogens in species level,for the high species diversity and little morphological differences.We re-described eight Melampsora species infected in Populus in China from the views of morphology and phylogeny.In addition,a key of poplar Melampsora species from China was proposed.
