不同碳源对3种羊肚菌菌丝生长的影响

为了获得野生羊肚菌资源，并探讨其菌丝生长的最适碳源，本试验以QYY、XF、JJZ羊肚菌为供试菌株，以菌丝长势、密度、均匀度、菌丝生长速率和菌丝生长指数为指标，考察7种碳源对3种羊肚菌菌丝生长的影响。结果表明，3种羊肚菌菌丝对供试的7种碳源均能利用，表明羊肚菌对碳源的利用谱较广。而不同产地的羊肚菌对碳源的利用各不相同，QYY、XF、JJZ羊肚菌的最适碳源分别为可溶性淀粉、甘露醇、葡萄糖，菌丝生长速率分别为7.28、 8.22、 3.94mm/d，菌丝生长指数分别为36.39、41.11、15.78。

Effect of Different Carbon Sources on Mycelia Growth of 3 Kinds of Morchella esculenta

To obtain the wild resources of Morchella esculenta, and discuss the optimal carbon sources, we selected QYY, XF and JJZ Morchella esculenta as the tested materials, and mycelium growth, density, uniformity, mycelium growth rate and mycelium growth index as the indexes, to study the effect of seven kinds of carbon sources on the mycelia growth of three kinds of Morchella esculenta. The results showed that the mycelium of the 3 kinds of Morchella esculenta could utilize the 7 kinds of carbon sources, indicating that the utilization spectrum of Morchella esculenta for carbon sources was wide. The utilization of carbon source of Morchella esculenta from different places was different. The optimal carbon sources of QYY, XF and JJZ Morchella esculenta were soluble starch, mannitol and glucose. The mycelium growth rate was 7.28, 8.22, 3.94 mm/d, respectively, and the mycelium growth index was 36.39, 41.11 and 15.78, respectively.
