摘  要:
2011~2012年通过对苏鲁两省杨树白粉病害的调查,采集病原标本进行了室内切片鉴定,描述了症状及病原菌的形态,分析了寄主及分布范围。结果表明,根据病原菌的形态特征,引起苏鲁两省杨树白粉病的病原菌被鉴定为杨球针壳,该菌为害I-69杨、I-72杨、I-107杨、NL895杨和中华红叶杨属首次报道。杨球针壳能寄生在多种杨树上,严重时引起杨树提前落叶;同时发现,杨球针壳、落叶松杨叶锈菌的夏孢子阶段和杨盘二孢菌3种病原菌同时生长在同一张杨树叶片上,引起3种类型的病害症状,这种现象也属首次报道。

摘  要:
A powdery mildew on Poplars was studied for its occurrence,damage,and distribution in Jiangsu and Shandong provinces.Results showed that the powdery mildew was able to infect a number of species hybrids,and cultivars of Populus and caused premature defoliation.According to its morphological characters,the pathogen occurred in the two provinces was identified as Phyllactinia populi.It was reported for first time on Italian hybrid Poplar cultivars: I-69,I-72,I-107,and Populus deltoides cv.Zhonghua hongye.Its co-occurrence with uredia of Melampsora larici-populina and Marssonina brunnea on the same leaf was reported for first time also.
