Evaluation of medicinal asexual strains of Xanthoceras sorbifolium
摘要
Abstract
[Objective]This study aimed to evaluate the variation in phenotypic traits,leaf nutrient content,and enzyme activities among 23 clonal lines of Xanthoceras sorbifolium,and to examine their interrelations.The findings aim to provide a scientific foundation for the targeted cultivation,introduction and promotion of superior clonal lines of leaf-use X.sorbifolium.[Method]Twenty-three clonal lines of X.sorbifolia,introduced to Yancheng Forest Farm in Jiangsu Province,were used as research subjects.Variation was assessed by analyzing the coefficient of variation across 15 key indicators.Pearson correlation coefficients were calculated to determine the relationships between phenotypic traits,leaf nutrients and enzyme activities.Principal component analysis and hierarchical clustering were applied to comprehensively evaluate and classify the clonal lines.[Result]The 15 indicators exhibited varying degrees of variation,with coefficients ranging from 6.17％to 43.00％.Significant correlations were identified:nine pairs of indicators showed extremely significant correlations(P＜0.01),while five pairs demonstrated significant correlations(P＜0.05).[Conclusion]Leaf traits among the clonal lines of X.sorbifolium display substantial variation,indicating strong potential for selective improvement.The superior clonal lines identified were 50,Y8 and Y11,which are recommended for further cultivation and introduction in the Yancheng region.关键词
