野生木耳担孢子萌发特性研究

Study on Basidiospore Germination Characteristics of Wild Auricularia sp.

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24h不能萌发，36h时可萌发产生芽管，60h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。

In order to elucidate basidiospore germination process of wild A uricularia sp., the germination characteristics were studied by using shaking culture. The results showed that the basidiospore was not germinated after 24 h in sterile water, however, the basidiospore could germinate and produce germ tubes by 36 h. The germ tubes could branch and produce 1 to 4 conidia at the top ends at 60 h. The basidiospore of A uricularia sp. could germinate and produce primary hyphae or conidia directly.
