摘　　要：以茶树菇2511菌株为试材,通过比较菌丝生长速度以及菌丝生物量,研究了14种不同C/N培养基以及8种不同碳源物质、11种氮源物质对茶树菇菌丝生长的影响,旨在筛选出母种阶段适宜茶树菇菌丝生长的最适C/N培养基及最适碳源和氮源物质。结果表明：最适C/N为27∶1~33∶1,最适碳源物质为葡萄糖,其次为蔗糖;最适氮源物质为酵母浸粉。In order to select the most suitable C/N culture medium,as well as the carbon and nitrogen source material for the mycelial growth of Agrocybe aegerit, the effect of the cultivation characteristics about the strains 2511 mycelial growth with 14 kinds of C/N culture medium as well as 8 kinds of carbon source material and 11 kinds of nitrogen source material by the method of the comparison about the mycelial growth rate and biomass were studied. The results showed that the most suitable C/N culture medium was from 27 ： 1 to 33 ： 1, the most suitable carbon source material was dextrose,the second was sucrose,the most suitable nitrogen source material was yeast extract powder.
