植物霜霉病菌卵孢子的形态特征是霜霉菌分类的依据之一。因教学或科研工作需要,常须制作霜霉菌卵孢子的玻片标本,但由于霜霉菌的卵子产生于枯死或衰老的病组织中,用常规的制片方法镜检不到,须采用特殊的制片方法,才能制出理想的玻片标本。我们在实验室工作中摸索出几种不同的霜霉菌卵孢子玻片标本的制作方法,现介绍如下。1 葡萄霜霉菌 10月中、下旬,选已枯黄的 Plant downy mildew conidia spore morphology is one of the basis for the classification of downy mildew. Due to teaching or scientific research work, often need to produce downy mildew oospores of slide specimens, but downy mildew eggs produced in the dead or aging of the diseased tissue, with the conventional method of microscopic examination, to be used special Production methods, in order to make the ideal slide specimen. We work in the laboratory to explore several different methods of production of downy mildew oospores slide specimens are presented below. 1 grape downy mildew October mid-late, the election has been yellow
