天麻属兰科植物,是一种重要的常用中药材。由于它无根、无叶,不能进行光合作用而自养.多年来,有关学者大都认为其整个生长周期都是靠蜜环菌提供营养,进行无性繁殖。天麻种子极小,仅由胚及种皮构成,无胚乳及其他营养储备,因此种子发芽异常困难。70年代中期,医学科学院药用植物资源开发研究所(原药研所栽培室)与陕西省合作,研究成功夭麻有性繁殖-树叶菌床法,即将天麻种子播种在带有蜜环菌材的树叶播种床上,发芽率达7.43％,播种
Gastrodia is an orchid plant, is an important common Chinese herbal medicines. Since it has no root, no leaf, can not carry out photosynthesis and autotrophic .For many years, most scholars believe that its entire growth cycle is provided by the honey ring fungus to provide asexual reproduction. Gastrodia seeds is extremely small, composed of embryos and seed coat only, without endosperm and other nutrient reserves, so the seeds germinate exceptionally difficult. In the mid-1970s, the Institute of Medicinal Plant Resources Development of the Academy of Medical Sciences (formerly the Institute of Pharmaceutical Research and Cultivation) collaborated with Shaanxi Province to study the success of the sexual reproduction of the disease, the leafy bed method, The leaves of seeding bed, germination rate of 7.43%, sowing
