香菇子实体多糖得率的差异性研究

Study on the Difference of Lentinus edodes Fruiting Body Polysaccharide Yield

以香菇子实体为研究材料,比较不同潮次、部位、成熟度的香菇子实体多糖得率的差异。研究结果表明:第1潮香菇多糖得率最低,其与第2、3潮香菇之间差异显著(P<0.05),且相关系数较低,分别为0.177 7、0.075 9,而第2潮与第3潮香菇多糖得率差异不显著,相关系数为0.775 0;不同部位(菌柄和菌盖)香菇多糖得率差异不显著,且它们的多糖得率相关系数高达0.986 6,表明菌柄和菌盖多糖得率之间相关性明显;不同成熟度香菇多糖得率差异不显著,且不同成熟度的香菇多糖得率之间的相关系数都较高,分别为0.926 9、0.974 3和0.963 9,即香菇子实体在不同生长时期多糖含量差异不大,香菇多糖的积累具有一定的关联性。考虑生产成本,最好采收第2潮成熟期香菇作为多糖类产品的生产原料。

With Lentinus edodes fruiting body as research material, fruiting body lentinan yield were compared in different batches, different parts and different maturity. The results showed that ： the lentinan yield of first batches was lowest, and there was a significant difference between the first batches and the second or third batches, the correlation coefficient was lower（which was 0. 177 7 and 0. 075 9）, and there was no difference between the second and third batches of lentinan, and the correlation coefficient between them was 0.775 0 ; there was no significant difference between different parts of lentinan yield, and the correlation coefficient between two different parts of lentinan yield is 0.986 6, indicating that the stipe and cap of lentinan yield is significant correlation ; different maturity lentinan yield were ： there was no difference between different maturity of lentinan yield, and the correlation coefficient were higher （ respectively 0.926 9, 0.974 3,0. 963 9）. Namely, the polysaccharide content of fruiting bodies at different growth stages was insignificant, and the accumulation of lentinan has a certain relevance. Considering the cost of production, the second tide and maturity Lentinus edodes fruiting body should be used as raw material.
