Abstract:
Objective To systematically evaluate the germplasm resources of Polygonatum odoratum(Mill.)Druce from the main producing areas in China.Methods A total of 35 tubers of Polygonatum odoratum from the main producing areas of China were collected to detect the water content,and the contents of nutrients including crude ash and crude fat,etc.and two medicinal components(polysaccharides and total flavonoids),and then the germplasm resources of Polygonatum odoratum were comprehensively evaluated by the coefficient of variation,correlation analysis and cluster analysis.Results In different Polygonatum odoratum tuber resources,the water content was 64.43%-83.78%,crude ash content was 1.03%-6.43%,lignin content was 2.83%-18.38%,cellulose content was 1.88%-4.73%,crude fat content was 2.85%-5.16%,crude protein content was 47.12-184.20 g/kg,the contents of polysaccharide and total flavonoids were 33.85-155.79 mg/g and 0.49-1.78 mg/g,respectively.Among them,the coefficients of variation for polysaccharide,crude ash,lignin,crude protein and total flavonoids were 0.45,0.42,0.38,0.31 and 0.30,respectively,showing large variations.There was a significant positive correlation between water content and contents of polysaccharide as well as various ingredient indexes in Polygonatum odoratum.The Polygonatum odoratum germplasm from different producing areas were mainly clustered into two types as follows:the first type was mainly from Guangdong and Hunan producing areas,the total flavonoids content being commonly higher,and the polysaccharide content of Polygonatum odoratum belongs to the second type in other producing areas was commonly higher.Four breeding materials with high content of medicinal ingredients were screened out by combining above indexes.Conclusion The high-quality germplasm was screened out through analyzing main nutrients and medicinal ingredients of Polygonatum odoratum tubers from different producing areas,contributing to providing data and material support for the evaluation of Polygonatum odoratum germplasm resources and strain breeding.
