摘要: 为了比较桃新品种在天津盐碱土壤上的果实品质差异,试验以3个晚熟桃新品种(‘国庆桃王’‘巨红冠’‘巨黄金’)为试材,测定了果实硬度、果形指数、单果重、含水量、可溶性固形物、可溶性糖、可滴定酸、糖酸比,维生素C等指标,并进行了隶属函数综合分析。结果表明:‘巨红冠’的单果重(414.50 g)、可溶性固形物(14.56%)、可溶性糖含量(8.12%),糖酸比(47.76),维生素C含量(8.12 mg/100 g)均最高,而‘巨黄金’均最低,但其果形指数(1.00)、含水量(87.21%)、果实硬度(1463.33 g/cm2)和可滴定酸含量(0.19%)均最高。综合分析显示,果实品质为‘巨红冠’>‘国庆桃王’>‘巨黄金’。

Abstract: In order to compare the differences of fruit quality among three new late-ripening peach varieties in saline-alkali soils of Tianjin, the quality(fruit hardness, fruit shape index, single fruit weight, water content, soluble solid, soluble sugar, titratable acid, sugar-acid ratio, vitamin C)of ‘Guoqingtaowang’, ‘Juhongguan’, ‘Guhuangjin’varieties were researched, and then analyzed by membership function. The results showed that single fruit weight, soluble solid, soluble sugar, sugar-acid ratio and vitamin C were highest in ‘Juhongguan’, and ‘Guhuang Jin’ were lowest, but fruit shape index, water content, fruit hardness and titratable acid were highest in it. In conclusion, the fruit quality was high in ‘Juhongguan’, middle in ‘Guoqingtaowang’, low in ‘Guhuangjin’.
