Abstract:

Guizhou is situated in the southwest China, the whole district is in subtropical and east-monsoonrange, annual average temperature is from 11℃ to 19℃. Guizhou has ancient flora and it's vegetation type is complex and diversity.There are 280 species (contain varieties)belonging to 66 families and 144 genera, which account for 33.8%, 10.3% and 5.3% of all spermatophyte respectively, and there are 31 endemic monotypic genera; and 4 Guizhou endemic genera, they are Tengia, Thamnocharia, Centratheropsis and Dicercoclados. Guizhou endemic species are the composition for forest resources in Guizhou, which are not kubstituted and these species all possess more biologic traits and inportant econornic value. We selected example Abies fanjingshanensis, Camellia luteoflora, Tutcheria kweichowensis etc., 60 kinds of Guizhou endemic plants, and investigated their original ecological environmental conditions, current situation index of germ plasma and conservation. Researched their narrow distribution principle, and utilization of germ plasma resource, and so on.The success of experimental research in introduction and cultivation,and mursery stock expanding propagation has been obtained. The sustainable utilization way and pattern for germplasma reaources of endemic plants in Guizhou have been proposed in this paper.

Key words: Guizhou endemic spermatophyte, Germ plasma resources, Nursery stock propagation technique, Utilization evaluation
