摘要
分别将供试草菇菌株在 - 18℃ (± 1℃ )和 4℃ (± 1℃ )下进行低温处理 ,并在 2 5℃下将经低温处理菌株对 6种碳源和 6种氮源的利用能力与对照比较。结果表明 ,不同草菇菌株对低温的耐受能力存在明显差异 ,低温使草菇菌丝复活时间延长、生长势减弱、生长速度减慢或丧失对部分氮源的利用能力。但邓庄V2 3 、DwV 1和白草菇等菌株经低温处理后 。
Volvariella volvaceastrains were treated with low temperature of -18℃(±1℃) and 4℃(±1℃), and their utilization ability for 6 different C sources and 6 different N sources was compared with the CK under 25℃. The results showed that the difference for low temperature tolerance was existed in V. volvacea strains tested. Generally speaking, the revivification time of V.volvacea mycelia was prolonged, the mycelial growth vigour was weakened, the mycelial growth rate was reduced and the utilization ability of the mycelia for some kinds of N sources was lost. But the mycelial growth rate of DwV 1,DengzhuangV 23 and Baicaogu after low temperature treatment was faster in some kinds of media than that of the CK.
