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’。
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’.
