几种白粉病菌的显微形态学分析

The Resource Collection and Microscopic Analysis of Powdery Mildew Fungi

运用微分干涉显微镜分别观察了南瓜、凤仙花、黄瓜及番茄叶片上白粉病菌的显微形态,对侵染这几类植物的白粉病菌的分生孢子的形状、大小、分生孢子梗的形状以及孢子梗上着生分生孢子的数目等进行了比较,结果表明,它们的分生孢子的大小、分生孢子梗的形状及孢子梗上着生分生孢子的数目都有所不同,进而证明这些白粉病菌不是同一个物种。

Microscopic observations of powdery mildew fungi on pumpkin （Cucurbita rnoschata）, garden nalsam （Impatiens balsamina）, cucumber （Cucurnis sativus） and tomato （Solanum esculantum） were conducted in the paper. The result indicated that the size of the conidia, the number of conidia on conidiosphore and the shape of conidiosphore of these powdery mildew fungi on different plants are different,manifesting that these powdery midew fungi are from different species.
