摘要:

为研究不同金柑品种果实基础品质和营养物质的差异,以国家果树种质(重庆)柑橘圃的6个金柑品种为研究对象,测定15个主要品质指标、20个功能成分指标和17个氨基酸营养指标,采用主成分分析和隶属函数相结合进行综合评价。结果表明:温光橘的果实品质较好,滑皮金柑类黄酮总量最高,温光橘和滑皮金柑酚酸总量较高,宁波罗纹和融安金柑氨基酸总量较高,滑皮金柑药效、苦味和芳香氨基酸含量最高,融安金柑甜味氨基酸最高,温光橘酸鲜味氨基酸稍高。通过主成分分析提取出4个主成分,贡献率达98.905%,再利用隶属函数分析获得6种金柑果实品质和营养价值的综合评价结果,最终得分排名为温光橘>宁波罗纹>滑皮金柑>温州金弹>宁波罗浮>融安金柑。温光橘和宁波罗纹综合品质和营养价值较高,可为丰富重庆柑橘品种、促进产业发展提供一定的科学参考。

Abstract:

To study the difference of fruit quality and nutrition of different kumquat varieties, 15 main quality indexes, 20 functional component indexes and 17 amino acid nutrition indexes of six kumquat varieties from National Fruit Germplasm (Chongqing) Citrus Nursery were determined as the research object, and comprehensive evaluation was made by combining principal component analysis and membership function method. The results showed that fruit essential quality of Fortunella obovata(Wenguangju) was much better, total flavonoids content of Fortunella classifolia(Huapi) was the highest, Fortunella obovata(Wenguangju) and Fortunella classifolia(Huapi) had high total phenolic acids content. both of Fortunella japonica(Luowen) and Fortunella classifolia(Rong’an) had higher total amino acid content. Efficacy, bitter and aromatic amino acid content of Fortunella classifolia(Huapi)was the highest, and sweet amino acid content of Fortunella classifolia(Rong’an) was the highest. Four principal components were extracted through the principal component analysis (PCA), and the contribution rate reached to 98.905%, then the membership function method was used to obtain comprehensive evaluation values of fruit quality and nutrition of six kumquat varieties, the final score ranking was: Fortunella obovata (Wenguangju)> Fortunella japonica(Ningbo)> Fortunella classifolia(Huapi)> Fortunella crassifolia(Wenzhou)> Fortunella margarita(Ningbo)> Fortunella classifolia(Rong’an). Above all, Fortunella obovata (Wenguangju) and Fortunella japonica(Ningbo) had high comprehensive quality and nutritional value. The result could provide new varieties choice for citrus industry development in Chongqing.
