OBJECTIVE
To study the effects of hyphae and their metabolites of Mycena anoectochila, M. dendrobii and M. orchidicola on promoting the protocorns multiplication of D. candidum and platelet growth of A.roxburghii.
METHODS
Add 20% (V/V) ground hypha or 10 mg/L ethyl acetate extracts of fermentation liquid respectively to the plant culture media.
RESULTS
The ground hypha of 3 Mycena and ethyl acetate extracts of M. orchidicola could promote the protocorn multiplication rate of D. candidum. The ground hypha of M. dendrobii could increase the numbers of bud and improve the platelet growth of A.roxburghii. The ethyl acetate extracts of fermentation liquid of M. anoectochila increased the numbers of bud and M. orchidicola significantly improved the platelet growth of A. roxburghii.
CONCLUSION
The effects of 3 Mycena Endophytic fungi on promoting growth of Dendrobium candidum and Anoectochilus roxburghii are related with their metabolites in and out of hypha.
目的
研究金线莲、石斛小菇和兰小菇的菌丝体及其代谢产物对铁皮石斛原球茎增殖和金线莲组培苗生长的影响。
方法
分别将20%（V/V）的菌丝体匀浆或10mg/L发酵液乙酸乙酯提取物添加到植物培养基中。
结果
3种小菇的菌丝体匀浆和兰小菇的乙酸乙酯提取物均能促进铁皮石斛原球茎的增殖率。石斛小菇的菌丝体匀浆能增加芽数并促进金线莲组培苗的生长。金线莲的发酵液乙酸乙酯提取物增加了芽数，兰小菇显著促进了金线莲组培苗的生长。
结论
3种小菇内生真菌对铁皮石斛和金线莲生长的促进作用与其菌丝体内外的代谢产物有关。
