采用振荡培养法研究了野生木耳担孢子的萌发特性。结果表明,木耳担孢子在无菌水中培养24 h不能萌发,36h时可萌发产生芽管,60 h后芽管出现分支,各分支顶端产生1个~4个分生孢子。试验发现,木耳担孢子可直接萌发产生初生菌丝或分生孢子。 Osmotic culture was used to study the germination characteristics of wild fungus spores. The results showed that P. euphorbiae could not germinate 24 h after culture in sterile water, and could germinate germinated at 36 h. After 60 h, the germinated bud appeared and one to four conidia formed on the top of each branch. The experiment found that the fungus spores can be directly germinated mycelium or conidia.
