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 volvaceastrains 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.
