摘　　要：【目的】了解眉山市主栽柑橘品种果实品质,对各个区县爱媛28和春见果实品质进行综合评价,为眉山市柑橘品种示范和推广提供理论依据。【方法】以眉山市爱媛28、春见果园采集的共72个果实为材料,测定果实品质,利用主成分分析和聚类分析对来自不同区县的同一品种进行综合评价,计算得分排名并筛选品质评价指标。【结果】各区县爱媛28果实几项外在品质指标(a*、单果质量、纵径、皮厚度)在不同区县间存在显著差异,内在品质指标各区县之间无显著差异;各区县春见果实内外品质指标均存在显著差异。对两品种果实品质指标通过主成分分析提取到4个主成分,累积贡献率分别为75.646%、76.940%。综合评价得分结果表明,爱媛28果实品质综合得分均值排列顺序为东坡区>仁寿县>丹棱县>彭山区;春见果实品质综合得分均值排列顺序为彭山区>东坡区>丹棱县>仁寿县>青神县。【结论】明确了眉山市主栽柑橘品种的品质表现和不同区县间的异同,对优化调整眉山市柑橘品种结构、提高眉山市整体柑橘果实品质具有一定的参考意义。【Objective】The study aimed to understand and master the fruit quality of the main citrus vari-eties in Meishan City,and comprehensively evaluate the fruit quality of each variety in various districts and counties to provide theoretical basis for the adjustment and promotion of citrus variety structure in Meishan City.【Methods】Using Ehime 28(Citrus reticulate)and Harumi[C.reticulate×(C.reticula-ta×C.sinenesis)]orchards collected from 4 or 5 districts and counties in Meishan City as materials,15 kinds of fruit quality indicators were measured,and principal component analysis was used to compre-hensively evaluate the same variety from different districts and counties,and the score ranking was cal-culated.【Results】The single fruit weight of Ehime 28 varied from 149.8 g to 353.13 g,with an average of 245.24 g.The soluble solids content(TSS)range was 7.6%to 13.4%,with an average of 10.79%;The titratable acid content(TA)ranged from 0.49%to 0.94%,with an average of 0.70%;The vitamin C content(Vc)ranged from 26.4 mg·100 mL-1 to 50.47 mg·100 mL-1,with a mean of 36.82 mg·100 mL-1;The variation range of TSS/TA was 10.42-21.25,with an average of 15.66.The single fruit weight of Harumi varied from 162.38g to 392.74 g,with an average of 242.84 g.The distribution range of TSS was 9.7%to 13.7%,with an average of 10.97%;The distribution range of TA was 0.4%to 1.2%,with an average of 0.81;The distribution range of Vc was 24.95 mg·100 mL-1 to 42.71 mg·100 mL-1,with a mean of 35.37 mg·100 mL-1;The distribution range of solid acid ratio was 8.82-27.99,with an average of 14.43.Discriminant analysis showed that the comprehensive quality of Ehime 28 and Harumi fruits collected from different districts and counties had varying degrees of separation,and the comprehensive quality of the citrus fruits collected from the same district and county tended to cluster together,indicat-ing that there are certain differences in the comprehensive quality of the citrus fruits collected from dif-ferent districts and counties.11 frui
