摘　　要：测定了长根菇（Ｃｏｌｌｙｂｉａｒａｄｉｃａｔａ）在大豆饼粉蔗糖培养基内，深层发酵过程中发酵液的碳、氮消耗和ｐＨ值变化、菌丝干重以及多糖的动态变化。分别对菌丝体干重、菌丝体水溶性多糖和菌丝体多糖含量与发酵时间进行回归相关分析，结果表明菌丝体水溶性多糖不仅与菌丝体干重有关，而且与菌丝体多糖总含量有关；二元回归相关分析进一步表明：复相关系数和偏相关系数均达极显著水平。The changes of carbon, nitrogen sources,pPH value, mycelial dry weight, and polysaccharide content in culture of Collybia radicata in soybean meal-sucrose medium were determined. Regression analyses of mycelial polysaccharide content and culture time were carried out. The results showed that soluble mycelial polysaccharide content related not only to mycelial dry weight but also to mycelial polysaccharide content. The result of binary regression analysis showed that both multiple regression coefficient and partial regression coefficient attained the levels of highly significance.
