摘 要：
The resources of wild Rauvolfia yunnanensis Tsiang population were investigated in Dehong Prefecture. Based on the cutting seedling of superior individual,this paper carried out the clonal test and studied the content of reserpine and yohimbine. The results showed that "Dehong No. 6" Rauvolfia yunnanensis had the characteristics of fast growth,large biomass,high content of reserpine and yohimbine and good disease and drought resistance,which could be popularized for planting in the tropical and subtropical areas of Yunnan with an elevation of 600 ~ 1 200 metres,an annual average temperature of 20 ~22℃,an annual average rainfall above 1000 mm and the more than 1 m thickness of red soil and yellowred soil.
