[The relation between the seed germination and seedling development of Bletilla striata and Mycena osmundicola etc. fungi].
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.
