【Abstract】 Gastrodia elata is a plant belonging to orchidaceae family whose root and leave are degenerated without the ability to carry out photo synthesis,but can grow and develop with Armillaria mellea by symbiosis. Its cycle of growth and development from seeds to seeds is much changable under artificial control. Our previousexperience on the sexual propagation of the plant in Guizhou showed that two to four years are needed for its growth and development. It is now found that the cycle can be shortened to two years in the greenhouse partly through breeding and artificial pollination for mature fruit and plumpy seeds and partly through reasonable designing and sowing half a month in advance. So G. elata can be available on the market one or two years earlier.更多还原
