黑木耳的抗霉能力、产量性状与不同胞外酶活的相关性

A Study on the Correlation of Mould-Resistant Ability and Yield Characteristic with Various Extracellular Enzyme Activity in Auricularia auricula

以三个单孢杂交的黑木耳菌株和沪耳1号为材料,研究了不同菌株的抗霉能力,产量以及胞外多酚氧化酶、漆酶、过氧化物酶、半纤维素酶、羧甲基纤维素酶活性之间的相关性。结果表明:不同菌株的抗霉性与产量呈正比,不同的胞外酶活性又与抗霉性有一定的相关性,从而为黑木耳的抗病育种和生产提供了理论依据。

Using three Auricuiaria auricula mono- spore hybrids and Huer No. 1 as testing material, the cor-relation of the mould - resistant ability and the yield of A . auricula with the activities of the extracellular polyphe-nol oxidase, laccase, peroxidasc, hemiccllulasc and CMC was studied, The results showed that the mould - resistant ability, related with the activities of various extracellular enzymes in certain degree, was positively related with the yield of A . auricula .
