【中文摘要】 灰樹花 (Grifolafrondosa)的耐硒和富硒能力較強。在含硒 10～ 30 0mg/kg的固體培養基上 ,菌絲均能生長 ,當硒含量超過 2 50mg/kg時 ,菌絲生長受到抑制。液體深層培養條件下 ,添加 10～ 2 0 0mg/kg硒 ,菌絲體富集硒的濃度范圍為 61.4～ 882 .1mg/kg ,但以添加 50mg/kg硒時菌絲體硒吸收率最高 ,為 4 .9%。
【英文摘要】 The Se resisting and Se accumulating characters of Grifola frondosa GrUV05 were studied in this paper. The results showed that the Se resisting and Se accumulating ability of G. frondosa GrUV05 mycelia was strong . Its mycelia could grow in the solid medium added with 10 to 300 mg/kg selenium, but when the selenium content was above 250mg/kg, its growth was inhibited. When the liquid medium was added with 10 to 200mg/kg selenium, the mycelium Se accumulation concentration reached 61.4 to 882.1 mg/kg. And the mycelium Se absorption rate of 4.9% was the highest when the liquid medium was added with 50 mg/kg selenium.
