多种黄精属种质资源不同组织部位生理特性的比较研究
Comparative Study on Physiological Characteristics of Different Tissue Parts in Various Polygonatum Mill.Germplasm Resources
摘要
Abstract
Objective:This paper aims to investigate the physiological characteristics of different tissue parts in exploring the development potential of non-traditional medicinal parts.Methods:Six Polygonatum Mill.materials(codes:SW1-SW6)were collected from Fujian Province.Various physiological and biochemical indices were measured,and correlation,principal component,and loading analyses were conducted.Results:The integration of physiological indicators from six materials demonstrated that different tissue parts exhibit a universal adaptive strategy for the formation of aboveground and underground niches in Polygonatum Mill.plants.The levels of malondialdehyde(MDA),catalase(CAT)activity,soluble protein content,and total flavonoid content in the leaves were significantly higher than those in other tissue parts(P<0.05),indicating that leaves possessed a strong adaptive capacity to the external environment.In contrast,the rhizome contained the highest polysaccharide content(P<0.05),supporting its recognition as the traditional medicinal part.Furthermore,different germplasm materials showed distinctiveness:SW6 had abundant polysaccharide content in its rhizomes;SW1 accumulated high levels of total flavonoid content in its leaves and stems,while SW2 showed high polysaccharide content in its leaves and high flavonoid content in its roots,implying substantial accumulation of medicinal components in non-traditional medicinal parts;SW4 displayed the lowest MDA content across its leaves,stems,roots,and the whole plant,indicating superior environmental adaptability.Principal component analysis integrating multiple indices revealed that,in addition to the polysaccharide content in rhizomes,peroxidase(POD)activity of leaves significantly contributed a large loading to the characteristic information of germplasm materials,serving as an auxiliary index for germplasm identification.Moreover,variation among different tissue parts was affected by total flavonoid content,CAT activity,and polysaccharide content.Conclusion:Different Polygonatum Mill.germplasm materials exhibit various potential development values for edible,medicinal,and value-added applications.Different tissue parts also display unique physiological characteristics in antioxidant capacity and the accumulation of pharmacodynamic components.This study provides a reference for exploring the comprehensive utilization of various tissue parts in high-quality Polygonatum Mill.plants.关键词
