摘 要 ：银白杨,杨属植物,广泛种植于中国东北部地区,其锈病发生特别严重。在本研究中,根据形态特征和生活史将白杨锈菌鉴定为Melampsora laricis。使用杨树锈病叶片上的担孢子对日本落叶松及白山落叶松进行接种试验,结果证实了其精子器和锈子器世代发生在落叶松植物上。

Abstract:Populus alba is widely planted in northeast China and seriously infected with a rust fungus. In this study, the causal rust fungus of Populus alba was identified as Melampsora laricis based on its morphological characteristics and life cycle. Its spermogonial and aecial stages on Larix kaempferi and L.olgensis were confirmed by inoculations with basidiospores produced on P. alba.
