Abstract: 【Objective】 In order to provide theoretical references for comprehensive fruit quality evaluation of different pomegranates in Xinjiang.【Method】Six pomegranate cultivars were used as the tested materials to determinate the content of soluble solids, soluble sugar, titratable acid, and VC. The fruit quality of different pomegranate varieties was comprehensively evaluated by using principal components analysis.【Result】Results showed that there are some differences in fruit quality among different pomegranate varieties, and the soluble solids content of 'Yechengdazitianshiliu' was the highest (17.9%±0.6%); 'Kashisuanshiliu' had the lowest soluble solids content (14.9%±0.5%); 'Yechengtianshilu' had the highest titratable acid content (2.19%±0.38%); there were no significant differences among 'Yechengsuanshiliu', 'Kashitianshiliu' and 'Kashisuanshiliu' in titratable acid content. The soluble sugar content of 'Yechengtianshiliu' was (17.9%±0.6%), which was significantly higher than those of other five pomegranate cultivars; 'Piyamanshiliu' had the highest vitamin C content [(28.3±1.1) mg/100 g], which was significantly higher than those of other pomegranate cultivars.【Conclusion】Through principal component analysis, we concluded that 'Yechengdazitianshiliu' had the best fruit quality, followed by 'Yechengtianshilu', 'Piyamanshiliu' and 'Yechengsuanshiliu' and 'Kashisuanshiliu'.

摘要: 【目的】对新疆石榴果实品质进行主成分分析,为新疆石榴品质综合评价提供理论参考。【方法】以新疆主栽石榴对象,测定和比较其果实可溶性固形物、可滴定酸、可溶性糖和VC含量,采用主成分分析对不同石榴的果实内在品质进行综合评价。【结果】不同石榴在果实品质上存在一定差异,其中叶城大籽甜石榴的可溶性固形物含量最高(17.9 %±0.6 %),喀什甜石榴最低(14.9%±0.5%);叶城酸石榴的可滴定酸含量最高(2.19%±0.38%),叶城酸石榴、喀什甜石榴、喀什酸石榴三者之间的可滴定酸含量没有显著差异;叶城甜石榴的可溶性糖含量最高(17.9%±0.6%),显著高于其他石榴;皮亚曼石榴的VC含量超过[(28.3 ±1.1) mg/100 g],显著高于其他石榴。【结论】通过主成分分析综合评判叶城大籽甜石榴内在品质最佳,其后依次是叶城甜石榴、皮亚曼石榴、叶城酸石榴、喀什甜石榴和喀什酸石榴。
