摘　　要：通过在培养基中添加不同浓度的硒,考察菌体生长情况并测定不同生长阶段平菇胞外羧甲基纤维素酶、木聚糖酶、滤纸酶、淀粉酶活性,分析硒元素对平菇生长及胞外酶分泌的影响。结果表明,不同浓度的硒对平菇4种胞外酶均有显著影响,300 mg/kg硒有效促进了平菇胞外酶的分泌,在一定硒浓度范围内,硒对于食用菌的生长具有促进作用。The extracellular enzyme activities of Pleurotus ostreatus were tested in the presence of different concentrations of selenium cultivated in solid medium.The results showed that different concentrations of selenium had significant effects on the four extracellular enzymes of Pleurotus ostreatus,300 mg/kg selenium promoted the secretion of extracellular enzymes of Pleurotus ostreatus effectively,selenium promoted the growth of edible fungi in a certain range.
