基于主成分分析和聚类分析的榴莲品质综合评价

Comprehensive Evaluation of Durian Quality Based on Principal Component Analysis and Cluster Analysis

  • 摘要: 为探究海南本土驯化主栽榴莲品种中热1号与其他主栽商业品种之间果实品质的差异,本试验利用差异显著性分析对11份榴莲品种的10个外观品质、5个营养品质和8个矿物品质指标进行比较,并采用主成分分析和模糊综合评判法进行综合评价。相关性分析显示,果肉重和果实纵径是与榴莲内在品质关联最多的果实外观品质指标。通过对测定的23项指标进行主成分分析,提取出5个主成分,其中主成分1和主成分2的贡献率分别为33.344%和19.889%,主成分1中“果实大小”(单果重,果实纵径,果实横径,果肉重)、K含量和Zn含量以及主成分2中Mg含量和Ca含量为榴莲品种评价中的主要指标。榴莲品种品质指标综合得分由大到小依次为:中热1号、苏丹王、康瑶金、江海、葫芦王、猫山王、黑刺、托曼尼、朱雀、D101、火凤凰。综上所述,中热1号和康瑶金的果实外观品质和K、Zn元素含量高,江海和苏丹王Mg、Ca元素含量高,黑刺和D101营养品质优良,均可作为优良榴莲种质资源进行引种。“果实大小”及Mg和Ca矿质元素含量是评价榴莲综合品质的关键性指标,为榴莲品种的品质筛选及鉴定提供参考依据。

     

    Abstract: In order to explore the difference in fruit quality between Hainan domesticated durian variety Zhongre No. 1 and other main commercial varieties, this experiment used the difference significance analysis to compare 10 appearance quality, 5 nutritional quality and 8 mineral quality indexes of 11 durian varieties, and the principal component analysis and fuzzy comprehensive evaluation method were used for comprehensive evaluation. Correlation analysis showed that pulp weight and fruit longitudinal diameter were the most relevant indicators of fruit appearance quality with durian internal quality. Through the PCA of 23 indexes, five principal components were extracted, of which the contribution rates of principal component 1 and principal component 2 were 33.344% and 19.889%, respectively. The "fruit size" (single fruit weight, fruit longitudinal diameter, fruit transverse diameter, pulp weight), K、Zn content in principal component 1, and Mg、Ca content in principal component 2 were the main indicators in durian variety evaluation. The comprehensive scores of durian variety quality indicators were as follows from large to small: Zhongre No. 1, Sultan King, Kang Yaojin, Jianghai, Hulu King, Musang King, Black Thorn, Tomani, Suzaku, D101, and Fire Phoenix. To summarize, Zhongre No.1 and Kang Yaojin had good appearance quality and high contents of K and Zn elements, Jianghai and Sultan King had high contents of Mg and Ca elements, Black Thorn and D101 had good nutritional quality, all of them could be introduced as excellent durian germplasm resources. "Fruit size" and Mg, Ca mineral elements content were the key indexes to evaluate the comprehensive quality of durian, which provided a reference basis for the quality screening and identification of durian varieties.
