2、化学方法测定可溶性固形物、可滴定酸、维生素C(Vc)和总糖含量等内在品质,并进行多重比较。【结果】外观品质上表现较好的有大宝、户太8号、红瑞宝和红伊豆,这些品种不仅单粒重超过10.00g,且单穗重达505.48~573.75g,均比其他品种重;夏黑果粒最小,单粒重6.49g,单穗重最轻,仅382.51g。在内在品质上,除夏黑可溶性固形物含量(17.57%)最高外,大宝、户太8号、红瑞宝和红伊豆可溶性固形物、可滴定酸和总糖含量均比其他品种高,维多利亚可溶性固形物含量(13.27%)、可滴定酸含量(o.24g/100mL)和总糖含量(14.45
3、g/100mL)均最低,大宝Vc含量最高,达1.05mg/100mL“结论】9个葡萄品种果实品质表现差异较大,大宝、户太8号、红瑞宝和红伊豆在重庆整体表现良好,适宜推广。关键词:葡萄;品质分析;品种筛选;重庆中图分类号:$663.01文献标志码:A文章编号:2095一l191(2014)ol一0076—04o一·-’●^●·’‘n●‘●ISomparat
