观察植物病原真菌在植物组织的细胞间隙蔓延或直接侵入细胞内的菌丝时,常常用水合氯醛或乳酚油或5％的氢氧化钾进行组织透明,但用此法观察小麦叶片组织中的白粉病菌吸器时,叶片上下表皮及内部各层次细胞组织重叠影响观察。为了教学的需要,摸索出一种制小麦白粉病菌吸器的玻片标本制作法:沙氏液-甘油法。现将方法与步骤介绍于下: Observation of plant pathogenic fungi in the plant cell interstitial spread or direct invasion of intracellular hyphae, often with chloral hydrate or lactoferrin or 5% potassium hydroxide for tissue transparency, but this method was observed in wheat leaf tissue Of the powdery mildew germ sucker, the upper and lower epidermis and the inner layers of the cell tissue overlap the impact of observation. In order to teach the need to explore a system of wheat powdery mildew bacteria slides specimen preparation method: Sabouraud - glycerol method. The methods and steps are introduced below:
