摘　　要：为了对富硒真姬菇营养价值进行评估,采用真姬菇‘白玉10号’为试验菌株,菌草24号、本地配方作为富硒培养基进行栽培,对真姬菇产量、转化率、子实体性状、含硒量及子实体成分进行研究。结果表明:硒的添加浓度、添加方式及培养料差异均会对产量、转化率及性状产生影响。在硒浓度设计范围内,本地配方可获得硒含量在0.46~52.29mg·kg^(-1),是本地CK含硒量的2.7~307.6倍,24号配方可获得含硒量在1.18~84.92mg·kg^(-1),是24CK的6.94~499.53倍,子实体的含硒量与硒浓度呈正相关性。成分方面,子实体含水量、灰分和粗蛋白与硒浓度呈负相关性,而硒对子实体多糖合成有促进作用,但对总糖、脂肪的合成没有明显的促进或抑制作用。The nutritional value of mushrooms grown on selenium （Se） -enriched medium was studied. Hypsizigus rnarrnoreus No. 10 was cultivated on JUNCAO No. 24, and a local formula enriched with Se. The yield, conversion rate, fruiting traits. Se content and composition of fruiting body of the mushrooms were determined. The results showed that the amount and means of Se addition as well as the substrates in the cultivation affected the yield, conversion rate and properties of the mushrooms grown on the medium. In the concentration range tested, the Se content of H. marrnoreus cultivated on the local formulation increased to 0.46 - 52.29 mg · kg^-1, 2.7 - 307.6 times of that of control; whereas, on JUNCAO No. 24, the mushrooms grew to contain Se 1.18- 84.92 mg· kg^-1, which was 6.94- 499.53 times of that of control. The Se content of the fruiting bodies of the mushrooms increased with the increasing Se of the medium. But the contents of water, ash and crude protein of the mushrooms inversely correlated with the Se concentration in the substrate. The Se appeared to promote the polysaceharide formation in the fruiting body, but showed no significant effect on either sugar or fat synthesis.
