摘要
本文报道白芨种子荫发特点及紫萁小菇等4种真菌在其萌发中的作用。实验结果表明:白芨种子在常规条件下能正常发芽,为兰科植物中易萌发的种子类型。种子伴紫萁小菇等4种真菌播种,真菌对原球茎的子叶分化、生长及假根形成均有显著促进作用。用紫萁小菇培养物的醇、水粗提液及二者混合液播种种子,混合液有利于种子萌发;醇提液可加快原球茎子叶的分化与生长,且效果显著。
This paper reports the effects of Mycena osmundicola etc. fungi on the seed germination and seedling growth of Bletilla striata. The results showed that B. striata seeds are easily germinated under normal conditions and belong to a special type among Orchidaceae. Fungi promote cotyledon differentiation and growth, as well as rhizoid formation of B.striata protocorms after seeds are sown with fungi. A liquid extract mixture enhanced the percentage of seed germination, and carbinol extract notably accelerated differentiation and growth of the protocorm's cotyledon after seeds were incubated with the liquid extract of Mycena osmundicola-culture products.
