title: [Cytological observation on hyphae invading Mycena osm undicola in the process of seed germination of Gastrodia elata Bl].
abstract: In order to obtain the nutrition necessary to sprout, Gastrodia elata seeds depend on digesting a kind of fungi (Mycena osmundicola Lange). Hyphae are enclosed and digested by embryonic cytoplasm after M. osmundicola penetrates the embryo through suspensor cells, and then meristem cells begin to divide. The digested hyphae penetrate into large cells to be further digested. The body of the embryo then enlarges and germinates under meristem cells using the nutrition thus obtained.
