摘　　要：在分析获得甜瓜中18项营养品质指标数据基础上,通过主成分分析,对甜瓜品质代表性指标进行研究筛选,再借助聚类分析方法,探讨13种不同品种甜瓜的营养品质特点。结果显示:18项指标中灰分、脂肪、V B1、烟酸、酒石酸、蔗糖、总糖、可溶性固形物、总酸在对应主成分中的载荷值相对较高,能较好地反映数据整体变异情况;受试13种甜瓜大致可聚为两类,第1类以86、杂交伽师瓜为代表;第2类以伽师瓜、西州蜜25号为代表。综上所述:灰分、脂肪、V B1、烟酸、酒石酸、蔗糖、总糖、可溶性固形物、总酸可作为甜瓜品质特点的代表性表征指标;以86、杂交伽师瓜为代表的一类甜瓜具有灰分、V B1、烟酸、酒石酸、蔗糖、总糖、可溶性固形物含量相对丰富的特点;以伽师瓜、西州蜜25号为代表的一类甜瓜具有脂肪和总酸含量相对丰富的特点。The aim of this study was to screen the representative indexes of melon nutritional quality and identify the nutritional quality characteristics of different varieties of melon.Based on the data of 18 nutritional quality indexes of melon,the principal component analysis(PCA)was used to select the representative indexes of melon quality.The results showed that the loading values of ash,fat,V B1,niacin,tartaric acid,sucrose,total sugar,soluble solids and total acid in the corresponding principal components of the 18 indexes were relatively high,which could better reflect the overall variation of the data.The 13 kinds of melon can be grouped into 2 groups.The second category was represented by Jiashi Gua and Xizhou Mi 25.In conclusion,ash,fat,V B1,niacin,tartaric acid,sucrose,total sugar,soluble solids,and total acid could be used as the representative characterization indexes of melon quality characteristics.One kind of melon,represented by 86,was rich in ash,V B1,niacin,tartaric acid,sucrose,total sugar,and soluble solids.The melon of Jiashi type was rich in fat and total acid.The results of this study could provide a characteristic index basis for evaluating the nutritional quality of melon and lay a foundation for the subsequent classification and classification of melon.
