【摘要】 采用电泳技术对我国大规模栽培的64个平菇商业菌株进行酯酶同工酶分析。结果表明,我国栽培平菇菌种多样性丰富,64个菌株有44个酶谱类型,不同菌株有各自特有的酯酶同工酶酶谱。聚类分析表明,供试菌株在60%相似水平上分为6大类:第一类包括以白黄侧耳为代表的21个菌株;第二类包括以德国引进菌株为代表的6个未定种名菌株;第三类包括7个白黄侧耳与佛罗里达侧耳杂交的杂交种及4个未定种名菌株;第四类包括以佛罗里达侧耳为代表的5个菌株;第五类包括以糙皮侧耳为代表的14个菌株;第六类包括以肺形侧耳为代表的7个菌株。更多还原

【Abstract】 Esterase isozyme analysis was used in the study of 64 commercial strains of oyster mushroom. The results showed that there was great diversity among cultivated oyster mushroom. Forty-four zymogram types were observed in all strains tested. Differences of strains were expressed in their respective characteristic zymograms in the study. And the results of cluster analysis at 60% similarity level showed that all strains tested could be clustered into six groups, i.e.21 strains represented by Pleurotus cornucopiae, 6 unidentified strains represented by a strain introduced from Germany, 7 hybrids of Pleurotus cornucopiae with Pleurotus florida and 4 unidentified strains, 5 strains represented by Pleurotus florida, 14 strains represented by Pleurotus ostreatus and 7 strains represented by Pleurotus pulmonarius.更多还原
