摘要:

为筛选适宜滨海地区栽培应用的茶菊品种,测定比较了10个茶菊品种的植株、叶片及头状花序相关的13个农艺性状和3种有效成分,并利用相关分析、主成分分析结合隶属函数法对其在滨海地区的生态适应性和营养品质进行综合评价。结果表明,不同茶菊品种农艺性状间存在差异且变异丰富,变异系数在20.02%~65.87%之间;各品种绿原酸含量在0.55%~1.32%之间,3,5-O-二咖啡酰基奎宁酸含量在0.67%~2.24%之间,木犀草苷含量在0.13%~1.38%之间。主成分分析提取到4个主成分,累计贡献率达90.77%,叶长、叶宽、叶片重、花径、花瓣数、花瓣层数及木犀草苷含量等指标可作为主要评价指标。结合隶属函数法对10个茶菊品种进行综合评价,得出‘贡黄菊’‘金丝皇菊’‘晓起皇菊’和‘玉台1号’综合表现较好,在滨海地区具有较强的适应性。研究结果为茶菊资源在滨海地区的推广应用提供参考。

Abstract:

In order to screen out the varieties of tea Chrysanthemum suitable for cultivation and application in coastal areas, 13 agronomic traits related to plant, leaf and flower morphology and 3 effective components of 10 tea Chrysanthemum varieties were measured and compared. The ecological adaptability and nutritional quality of different varieties of tea Chrysanthemum in coastal areas were comprehensively evaluated by correlation analysis, principal component analysis and membership function method. The results showed that there were differences in agronomic traits among different varieties of tea Chrysanthemum, and the coefficient of variation ranged from 20.02% to 65.87%. The content of chlorogenic acid ranged from 0.55% to 1.32%. The content of 3,5-o-dicaffeoyl quinic acid ranged from 0.67% to 2.24%. The content of luteoloside ranged from 0.13% to 1.38%. 4 principal components were extracted by principal component analysis, with a cumulative contribution rate of 90.77%. Leaf length, leaf width, leaf weight, flower diameter, petal number, petal layer number and luteolin glycoside content could be used as the main evaluation indexes. Combined with the membership function method, the comprehensive evaluation of 10 varieties of tea Chrysanthemum showed that ‘Gonghuangju’ ‘Jinsihuangju’ ‘Xiaoqihuangju’ and ‘Yutai 1’ had better comprehensive performance and strong adaptability in coastal areas. The results could provide reference for the application and promotion of tea Chrysanthemum resources in coastal areas.

Key words: tea Chrysanthemun, agronomic traits, effective components, principal component analysis, comprehensive evaluation
