中文摘要: 为阐明中国怀来产区不同葡萄品种的品质特性，比较8种主要葡萄品种的总糖、总酸、可溶性固形物、颜色、pH值等理化指标以及葡萄糖、果糖、蔗糖、有机酸和酚酸等品质指标，并通过多变量主成分分析建立不同品种与品质指标之间的相关性。结果表明，北冰红的成熟系数最高，为64.46，魏可的成熟系数最低，为24.03。马瑟兰、赤霞珠、光系列颜色偏暗，而龙眼比较透亮。这8种葡萄品种检测出的糖类主要是果糖和葡萄糖，未检测出蔗糖。酒石酸、苹果酸和柠檬酸是样品中的主要有机酸，其含量在2.19 g/kg～5.03 g/kg。主成分分析结果表明，魏可、龙眼和夏黑的特征是颜色参数较高，而赤霞珠、北冰红、马瑟兰、品丽珠和光系列的特征是总酚、酚酸、糖类和有机酸含量较高。
Abstract:In order to clarify the quality characteristics of different grape varieties in Huailai region of China，the physicochemical indices of total sugar，total acid，soluble solids，color，pH and the quality indices of glucose，fructose，sucrose，organic acid and phenolic acid of eight grape varieties were compared，and the correlation between different varieties and quality indices was established by multivariate principal component analysis.The results showed that Arctic Red had the highest maturity coefficient（64.46），while Weike had the lowest maturity coefficient （24.03）.Mattherland，Cabernet Sauvignon and Lighting series were darker，while longan was more transparent.Fructose and glucose were the main sugars detected in the eight varieties，but sucrose was not detected.Tartaric acid，malic acid and citric acid were the main organic acids in the samples，and their content ranged from 2.19 g/kg to 5.03 g/kg.The results of principal component analysis showed that Weike，Longan and Xiahei were characterized by high color parameters，while Cabernet Sauvignon，Arctic Red，Matheland，Pinellia and Lighting series were characterized by high contents of total phenols，phenolic acids，sugars and organic acids.
