香魏蘑菌丝培养特性及生长曲线的测定

The Cultural Characteristics of Hongwei Mushroom,Mycelium and the Measure of Growth Curve

以菌丝球的干重与培养时间作生长曲线，通过液体培养法培养，研究菌丝生长与培养时间的关系。结果表明：香魏蘑菌丝在0～5d生长缓慢，菌丝处于适应环境的阶段，而从第5～7天生长较快，是一个快速生长期，在第7天之后菌丝基本达到稳定；香魏蘑菌丝体在PDA平板上菌丝粗壮、整齐、洁白，多气生菌丝，呈放射状，生长旺盛，菌丝浓密，液体发酵培养形成的菌丝球细密，且菌丝球界面清晰，同时上清液透亮。

Based on the growth curve of the mycelium＇s dry weight and culture time, and the cultivation of the liquid culture means, we study the relationship between the mycelium growth and the culture time. The results showed that Hong Wei mushroom mycelium grows slowly between 0-5 days at the stage of adaptation to the environment. While from 5 to 7 days, which was a fast growth period, it grows very fast, and then 7 days later, mycelium grows basically stable. When the mycelium growths on the PAD plate, it will be sturdy, clean, white, and more aerial hyphae, and take on the shape of radiation. Meanwhile, it will be vigorous, dense and intertwined~ the mycelial pellets, cultivated by the liquid fermentation, were fine and dense, and the interface of the pallets was clear. At he same time, the supernatant was translucent.
