Abstract:

From the viewpoint of genetics, the morphological structure, physiological function and ecological habit for each species of plant arc controlled by their own germplams, so that each species of plant represents an unique gcrmplasm resource. The Yunnan tropics occupy an area of 80900 km2, which is only 21 of the total area of the province, however, distributed 6000-7500 species of vascular plant in the tropics, 50 of the species of the province, where is the treasure of germplasm in Yunnan honoured "The kindom of plant".

Key words: Yunnan tropics, Tropical plant germplasm resources, Protective exploitation, Efficient protection
