60份不同种质宁夏枸杞干果品质及矿物质元素综合评价分析

Comprehensive Evaluation and Analysis of Dried Fruit Quality and Mineral Elements of 60 Different Germplasms of Lycium barbarum L.

  • 摘要: 基于宁夏枸杞干果品质及矿物质元素含量差异与相关性研究,建立综合评价体系筛选优良种质,为枸杞品质育种提供理论基础。以60份种质的干果为材料,测定16项品质及矿物质元素指标含量,采用变异系数、相关性分析和因子分析筛选核心评价指标,利用层次分析、灰色关联分析和聚类分析构建枸杞干果品质综合评价体系。结果表明,不同种质营养成分、常量元素和微量元素含量存在显著性差异,总糖含量、甜菜碱含量与Zn含量,多糖含量与Fe含量,类胡萝卜素含量与Mg、Se含量,黄酮含量与B、Zn和Ca含量,脂肪含量与Se、Mg含量呈极显著正相关(P<0.01);总糖含量与类胡萝卜素含量,蛋白质含量与Zn含量呈极显著负相关(P<0.01);因子分析筛选出9项核心指标,前8个因子累积贡献率为85.591%;层次分析将这9项核心指标分成营养因子、常量元素因子和微量元素因子三类,核心指标综合权重分别为多糖(0.138)、类胡萝卜素(0.269)、黄酮(0.373)、脂肪(0.220)、Ca(0.474)、Mg(0.606)、Fe(0.394)、B(0.123)、Se(0.403);欧氏距离为8.63时将60份种质分为五大类,因子分析法和灰色关联分析法皆筛选出‘宁农杞3号’、‘宁农杞9号’、‘14-06-11-12’、‘14-02-03-21’和‘14-04-03-13’为优良种质。宁夏枸杞种质干果品质及矿物质元素综合评价分析,初步揭示了干果品质与常/微量元素含量间的关系,筛选出了5种优良种质。

     

    Abstract: Based on the differences and correlations of quality and mineral elements content in dried fruit of Lycium barbarum L., a comprehensive evaluation system was established to screen the excellent germplasms, also to provide theoretical basis for high quality breeding of Lycium barbarum L.. The 16 qualities and mineral elements content of dried fruit in 60 germplasms of Lycium barbarum L. were measured. The core evaluation indexes were screened by coefficient of variation, correlation analysis and factor analysis, and the comprehensive evaluation system of dried fruit quality of Lycium barbarum L. was constructed by analytic hierarchy process (AHP), grey correlation analysis (GCA) and cluster analysis (CA). The results showed that there were significant differences in nutritional components, constant element and trace element contents among different germplasms. There were significant positive correlations between total sugar content, betaine content and Zn content, polysaccharide content and Fe content, carotenoids content and Mg, Se content, flavonoids content and B, Zn, Ca content, fat content and Se, Mg content (P<0.01), while there were significant negative correlations between total sugar content and carotenoids content, protein content and Zn content (P<0.01). Nine core indexes were filtered out by factor analysis, and the accumulative contribution rate of the first eight factors was 85.591%. The AHP divided the nine core indicators into three categories, which were nutritional factors, constant element factors and trace element factors. The comprehensive weight of core indexes were polysaccharide (0.138), carotenoids (0.269), flavonoids (0.373), fat (0.220), Ca (0.474), Mg (0.606), Fe (0.394), B (0.123), Se (0.403). The 60 germplasms could be divided into five categories when the Euclidean distance was 8.63, and 'Ningnongqi No.3', 'Ningnongqi No. 9', '14-06-11-12', '14-02-03-21' and '14-04-03-13' were the relative excellent germplasms selected by both factor analysis and grey correlation analysis. The comprehensive evaluation and analysis of dried fruit quality and mineral elements of different Lycium barbarum L. germplasms revealed the relationship between dried fruit quality and the content of constant and trace elements, and 5 excellent germplasms were selected finally.
