Analysis of morphological indexes and quality characteristics of Polygonatum sibiricum in different ecological planting areas
Samples of Polygonatum sibiricum were collected from six Polygonatum cultivation bases in five main producing areas in Tongren,Guizhou Province,the relationship between the quality characteristics of rhizome of P.sibiricum(dry rate,extract,polysaccharide,total ash)and the morphological characteristics of rhizome(plant height,stem diameter,solid content of aboveground part,number of fibrous roots,root length,fibrous root diameter and solid content of root system)was analyzed.The results showed that the quality indexes of rhizome of P.sibiricum from different ecological planting areas were all in accordance with the limit value stipulated,and the morphological indexes of P.sibiricum from different ecological planting areas were quite different,the main morphological indexes affecting rhizome quality of P.sibiricum include root length,fibrous root diameter,plant height,stem diameter,root number and solid content of root system.
