根霉由分枝状无隔菌丝组成,它的菌丝体由匍匐菌丝组成。接触培养基处向下分枝形成假根,向上生出成群的孢囊梗,是一种食品污染菌。在很多教科书中采用水滴法对它进行观察,结果是菌丝、孢子囊梗和孢子混合成团,难以观察到形态。本文通过插片法和埋片法观察根霉形态,效果较好。 Rhizopus is composed of branched, non-segregating hyphae, and its mycelium is composed of hyphae. The contact culture medium branches downward to form a false root, and gives rise to clusters of cysts, which is a kind of food contamination bacteria. In many textbooks, the water droplets were used to observe it. As a result, hyphae, sporangia, and spores were mixed and it was difficult to observe the morphology. In this paper, the morphology of Rhizopus was observed by insert method and buried plate method, and the effect was better.
