Research Progress on the Intraspecific Relationship of the Medicinal Plant Polygonatum sibiricum
Polygonatum sibiricum is a traditional Chinese medicinal material with the same origin as medicine and food.There are more than 60 kinds of Polygonatum in the world,and 31 kinds of Polygonatum are produced in China.Because of the similarity of epigenetic morphology and the overlap of genetic identification,the classification of Polygonatum plants has always been a difficult problem in academic circles.The genetic diversity of Polygonatum plants is rich and the variation range is large.This paper summarizes the latest research progress of Polygona-tum plants classification from the aspects of morphology,cytotaxonomy,chemical composition and molecular systematics,and analyzes the latest classification results.The current research on the classification of Polygonatum plant can provide data and theoretical support for the intermedi-ate division of Polygonum plants,the protection of medicinal plants and the utilization of resources.
