摘　　要：为了分析网纹甜瓜成熟过程中主要品质的变化并进行综合评价,本文以天津市‘碧龙’和‘瑞龙’两种品种网纹甜瓜花后15、30、45、50、55、60 d的果实为试验材料,通过对不同生长阶段果实的外形性状及品质性状指标的测定,运用主成分分析法对果实品质进行综合评价,为天津市设施网纹甜瓜的采收提供理论依据。经主成分分析,‘碧龙’提取了2个主成分,累计方差贡献率达91.257%。主成分分析综合得分模型显示,‘碧龙’花后50 d的果实评分排名第一,花后45 d的果实排名第二,花后55 d的果实排名第三,结合分析口感和营养排名,‘碧龙’最佳品尝时期为花后45~55 d。‘瑞龙’提取了2个主成分,累计方差贡献率达89.957%。主成分分析综合得分模型显示,‘瑞龙’花后55 d的果实评分排名第一,花后60 d的果实排名第二,结合分析品质和外形排名,得出‘瑞龙’最佳品尝时期为花后55~60 d。In order to analyze the changes in main quality indicators during the ripening process of netted melon and conduct a comprehensive evaluation,this article took the fruits of two varieties,‘Bilong’and‘Ruilong’,from Tianjin as experimental materials at 15,30,45,50,55,60 d after flowering.By measuring the appearance traits and quality traits of fruits at different growth stages,comprehensive evaluation of fruit quality used principal component analysis provides a theoretical basis for the harvesting of greenhouse netted melon in Tianjin.After factor analysis,‘Bilong’extracted two main factors,with a cumulative variance contribution rate of 91.257%.The comprehensive score model of factor analysis showed that‘Bilong’ranks first in fruit score on 50 d after flowering,the second was on 45 d after flowering,and the third was on 55 d after flowering.Based on the analysis of taste and nutritional ranking,the best tasting period for‘Bilong’was between 45-55 d after flowering.‘Ruilong’extracted two main factors,with a cumulative variance contribution rate of 89.957%.The factor analysis comprehensive score model showed that‘Ruilong’ranks first in fruit score on 55 d after flowering,and the second was on 60 d after flowering.Based on the analysis of quality and appearance ranking,the best tasting period for‘Ruilong’was between 55-60 d after flowering.
