Objective: To carried out the investigation on Sophora japonica germplam in Guangxi

in order to lay a foundation for assessing and selecting good S. japonica germplasm. Method: Field visit and literature review were adopted to investigate S. japonica germplasm in Guangxi. Result: ①S. japonica of Guangxi is mainly distributed in Quanzhou

Xingan

Yangshuo

Fuchuan

Gongcheng and other counties (cities)

where are located at 24°28'23"-26°22'15" north latitude

and 109°22'06"-111°16'21" east longitude

and most commonly seen at the altitude between 104-502 m. ②Different species of S. japonica have different leaf characteristics

plant size and quality of flower buds in different areas. S. japonica cultivated by Qiyi

Quanzhou is significantly superior to that in other areas. ③S. japonica is widely adaptable in Guangxi in terms of temperature

soil

precipitation. ④S. japonica in Guangxi has a fewer companion plants

but with prominent dominant families

especially the Composite family

which is followed by Gramineae

Plantaginaceae

Labiate

Euphorbiaceae. Conclusion: In this study

geographical distribution characteristics

growth characteristics and types of S. japonica are figured out

so as to provide the scientific basis for selecting good breeds of S. japonica in Guangxi.
