摘要
研究认识天麻的生活史.天麻种子无胚乳及其他营养贮备,无外源营养供给不能发芽.蜜环菌对天麻种子发芽有明显的抑制作用。发现天麻种子必须与紫萁小菇等萌发菌建立营养关系才能发芽.发芽后的原球茎在当年进行第一次无性繁殖,必须同化蜜环菌才能正常生长。天麻与紫萁小菇等萌发菌及蜜环菌先后共生,三年(24个月)完成由种子到下一代种子的全过程。
Seeds of G. elata are strongly reduced small structures. They lack nutrient tissues entirely. A small embryo is surrounded by a single-layered seed coat with a very loose structure. Digestion of certain kinds of fungi (Mycena osmundicola, etc) which have invaded the embryonic cells provides the necessary nutrition to sprout. Protocorms obtain their nutrition from invading Armillaria mellea and then go on to vegetative propagation, becoming small, white G. elata within a year. The commercial arrow G. elata can be obtained late in the year. Over the winter, it will bud, blossom and bear fruit, fallowing in the next year. Taking three years to complete its life cycle, G. elata depends upon the digestion of certain kinds of fungi ——Mycena osmundicola, A. mellea, etc.
