What are the reasons for the low survival rate of sexual reproduction in Gastrodia elata?
Gastrodia elata is a precious Chinese medicinal herb in China, and its cultivation area has been expanding year by year. Due to the degeneration of varieties in asexual reproduction, yields are low and unstable, and quality declines, which has affected commodity exports. At present, most growers use sexual crossbreeding to propagate seed tubers to solve the problem of yield reduction caused by variety degeneration in Gastrodia elata. However, there are also problems such as lack of proficiency in the technology and uneven quality of breeding, which have restricted the rapid development of Gastrodia elata, leading to the abnormal phenomenon that the more it is developed, the fewer the products and the higher the market price. Those who fail gain very little from the huge investment they made, which has greatly dampened farmers' enthusiasm for development. In response to the above
