冬虫夏草菌侵染及寄生阶段的生长发育研究

The growth of Cordyceps sinensis (Berk.) Sacc. in the infection and parasitic phases

冬虫夏草菌侵染进入寄主幼虫血体腔后,断裂形成长梭形的菌体。菌体以顶端出芽的方式增殖,分隔分化,互相质配。质配菌体生长出菌丝充满寄主幼虫血体腔,使幼虫死亡并形成僵虫形的菌核,菌核萌生子座即形成冬虫夏草。

It was observed that after Cordyceps sinensis invaded host larvae and entered the coelom, the mycelia fragmented into fusiform thalli. The thalli were multiplied by apical budding, and plasmogamy occurred, the mycelia filled the coeloms of the host larvae, resulting in the death of insects and forming sclerotia looking like rigid worms. The sclerotia germinates to form stromata.
