by Shiming Cheng, Ying Hu, Yan Cheng, Zhiyang Qian, Xiurong Xu, Xiashuo Lei, Xiaodeng Shi Polygonatum cyrtonema is a valuable medicinal and edible plant whose sustainable utilization is challenged by wild resource depletion and germplasm degradation. This study established a multi-site provenance trial across three heterogeneous garden environments in Zhejiang Province, China, to evaluate 11 geographically diverse provenances.
We systematically measured growth traits (plant height, stem diameter, leaf morphology) and medicinal components (polysaccharides, saponins, flavonoids, total phenolics), and applied combined ANOVA, correlation analysis, principal component analysis, and cluster analysis to quantify provenance variation patterns and environmental drivers. Results revealed highly significant differences (P P.
cyrtonema and holds significant practical implications for enhancing the quality and efficiency of the understory economy and promoting the sustainable use of medicinal plant resources.
