Metasequoia globosa (Metasequoia globosa), a Chinese yew belonging to a wiggery plant, is called "activated stone". According to investigation, the native metasequoia is only distributed in partial areas of Hubei, Hunan and Chongqing provinces of China, and the areas generally have the vertical elevation of 1000-1200m, abundant rainfall and appropriate climate. The metasequoia has beautiful tree shape, strong ornamental value, strong adaptability to the environment and fast growth speed.
At present, the metasequoia is successfully introduced and cultivated in China and many countries and cities in the world, and is often planted as shade trees, street trees, greening trees and protective trees. Since the discovery of metasequoia, scholars at home and abroad pay great attention to it. As a representative endangered plant with high protection and utilization values, the metasequoia also carries out comprehensive basic research on the metasequoia in all aspects and multiple disciplines by scholars and research institutions at home and abroad. The method has the advantages of developing the discovery process of the metasequoia, the dynamic research of the protospecies, the cultivation introduction technology, the protection of biology, morphological structure and chemical components and the like. Although the metasequoia is introduced and cultivated in China and all over the world, the protection of germplasm resources is still far from the point of view. Researches find that the germination rate of the metasequoia seeds is low in the natural environment, which may be one of the main reasons for endangering metasequoia populations. How to improve the germination rate of the metasequoia seeds and the strong seedling rate after germination is an important measure for protecting metasequoia population.
