Survey and Analysis of Cultivated Bupleurum spp.Germplasm Resources in China
Abstract:Objective:In order to assess the current status of cultivated Bupleurum germplasms in China,a survey was conducted throughout its main cultivation regions in China. Methods:Fifty-six cultivated Bupleurum population samples were collected from the main production regions of five provinces,the discovery and arrangement of morphological features were performed during investigations. Results:The areas of the cultivated Bupleurum are mainly distributed in the provinces of Gansu,Shanxi,Shaanxi,Hebei and Heilongjiang,most of which originated from local wild accessions or germplasms brought from other regions. There are many common names for the germplasms. The most commonly cultivated Bupleurum spp. can be divided into six types and four species[Bupleurum chinense DC.,B.scorzonerifolium Willd.,B.falcatum Linneus and B.marginatum var.stenophyllum (Wolff) Shan et Y.Li],of which B.chinense is the main cultivated species. Conclusion:It is of great significance to determine the source of cultivated Bupleuri Radix by combing,classifying,and identifying complex and diverse cultivated germplasms. Meanwhile,the novel distinguishing characteristics discovered in this study can be used as critical supplement for the identification of Bupleurum spp.,and contribute important references for the further research and development of Bupleuri Radix.
