贵州特有植物及其种质保存研究

STUDY ON ENDEMIC PLANT OF GUIZHOU AND IT'S GERM PLASM CONSERVATION

目前贵州特有或仅在贵州分布的种子植物共计280种(含变种),占贵州省种子植物总数的5.3%.它们分别隶属66科、144属.贵州特有植物,分布范围狭窄,环境恶化,它们不仅稀少,而且濒危.为此,三年来,我们择其具有显著代表性和开发应用前景较好的15种植物进行种质资源的保存研究工作.

There are 6, 000 species of higher plant in Guizhou, or which 4,950 species (varieties) are seed plants, there are many species of ancient endemic and solitary plants in Guizhou, and 280 species (varieties) ofendcmic plants belong to 66 families and 144 genus. The endemic plants account for 33.8% of all families, 10.3%of all genus. And there are 31 endemic monotypic genera of single type, 4 endemic monotypic genera of single species of China distributed there, which arc: Tengia, Thamnocharia, Centratheropsis and Dicercoclados.Because of the narrow distribution and the deterioration of environment, most of the endemic plants in Guizhou arc threatened to be extinct. 15 species' germ plasm conservation has been studied for 3 years, which focus on: 1, soil and humidity control, culture and time of introduction; 2, imitation of original environments ccocomm unities; 3, these endemic plants original from ancient incomplete plant, or original from plant development and evolution in original environments, This experiment supports the argument point of << Plant Toxonomy and Biosys Tematics>> by Clive A. Stace.
