摘要:

目的: 筛选兼具高药用成分(总黄酮、萜内酯)和低银杏酸含量的叶用银杏无性系,为叶用银杏优良品种的进一步选育和银杏叶用林的栽培提供无性系材料。方法: 测定46个银杏无性系的叶表型性状(单叶干质量、单叶面积、比叶干质量)、叶药用成分(总黄酮、萜内酯)和银杏酸含量,采用聚类分析、基于隶属函数的主成分分析法对46个无性系进行综合评价。结果: 46个银杏无性系的叶表型性状、叶药用成分和银杏酸含量等存在显著差异,表现出丰富的遗传多样性,平均变异系数为13.8%;基于隶属函数的主成分综合评价并结合聚类分析结果,筛选出25、34、1、5、45、3号6个综合表现优良且高药低酸型叶用无性系,这些无性系具有较大比叶干质量、较高总黄酮和萜内酯含量及中低银杏酸含量,其中34号无性系单叶面积、单叶干质量、总药用成分含量等均较高,银杏酸含量较低。结论: 不同银杏无性系的表型性状、主要药用成分和银杏酸含量变异丰富,药用成分和银杏酸存在一定协同变化,但药用成分之间的相关性更强,可为高药低酸型叶用银杏无性系选育提供可能。

Abstract:

Objective: This study aims to screen superior clones of Ginkgo biloba for leaf production with high medicinal components (total flavonoids and ginkgolides) and low ginkgolic acid content. Method: The phenotypic traits (dry weight per leaf, leaf area, specific leaf dry weight) and medicinal component contents (total flavonoids, terpene lactones) of leaves from 46 ginkgo clones, as well as ginkgolic acid content, were systematically measured. Cluster analysis and principal component analysis based on membership functions were employed to comprehensively evaluate the 46 clones. Result: There were significant differences in leaf phenotypic traits, medicinal component contents, and ginkgolic acid content among 46 ginkgo clones, indicating rich genetic diversity, with an average coefficient of variation of 13.8%. Based on the comprehensive evaluation using principal component analysis based on membership functions and combined with cluster analysis, six high-quality clones with high medicinal value and low ginkgolic acid content were selected, namely clones 25, 34, 1, 5, 45, and 3. These clones generally had higher specific leaf dry weight, higher contents of total flavonoids and terpene lactones, and moderate to low levels of ginkgolic acid. Among them, clone 34 had relatively larger leaf area, higher dry weight per leaf, and higher total medicinal component content, while its ginkgolic acid content was relatively low. Conclusion: There are abundant variations in phenotypic traits, main medicinal components and ginkgolic acid content among different ginkgo clones. There is a certain synergistic change between medicinal components and ginkgolic acid, but the correlation between medicinal components is stronger. The results provides the possibility for the breeding of leaf-using ginkgo clones with high medicinal components and low ginkgolic acid.
