7种柚子果实品质分析与模糊综合评判

[目的]评估福建地区几种主栽柚子品种的优劣,并挑选出优良的栽培品种。[方法]以红肉蜜柚、云南东试早、海南水晶柚、玉环1号、顺昌红心柚、西双版纳1号、美国强得勒7个柚子品种为试材,对各柚子品种果实的主要品质特性,如果形,单果质量,果形指数,可食率,VC、可溶性固形物、可滴定酸、可溶性糖的含量,糖酸比和固酸比等相关指标进行测定和比较分析,并在此基础上应用模糊综合评判法对柚子果实品质进行客观评价。[结果]试验表明,不同柚子品种在主要品质指标上存在显著差异,以玉环1号、顺昌红心柚表现较优,其次为西双版纳1号,其他品种果实的品质相关指标测定结果均存在或多或少的缺憾。[结论]对柚子果实品质进行客观评价时可使用模糊综合评判法。

Analysis of Fruit Quality and Fuzzy Comprehensive Evaluation of Seven Cultivars of Pomelos

Objective] To evaluate the quality of pomelo cultivars in Fujian Province, and to screen the high-quality cultivars.[Method] The seven pomelo cultivars (Hongrou pomelo, Yunnan pemelo, Hainan crystal grapefruit, Yuhuan 1, Shunchang pomelo, Xishuangbanna 1 and the United States Qiangdele) were selected as experiment materials.The main quality characteristics of pomelo cultivars were detected and analyzed, such as fruit shape, single fruit weight, fruit shape index, VC content, soluble solids content, titratable acid content, soluble sugar content, the ratio of sugar to acid and the ratio of solid to acid.Based on these, fuzzy comprehensive evaluation method was applied to evaluate the fruit quali-ty of pomelo.[ Result] There were significant differences in the major quality indexes of pomelo cultivars.Among them, Yuhuan 1 and Shun-chang pomelo showed the optimal performance, followed with Xishuangbanna 1.Detection results of quality related indicators of other cultivars had some disadvantages.[Conclusion] Fuzzy comprehensive evaluation method can be used for the objective evaluation of pomelo fruit quality.
