摘要: 以湖南省怀化市刺葡萄品系中的甜葡萄(Vitis davidii Foex. cv. Tianputao)品种为试材,设置3 个产量水平,分别为1 300 kg/667 m2(L1)、1 900 kg/667 m2(L2)、2 500 kg/667 m2(L3),分别测定各产量水平下葡萄的总酸、还原糖、单体花色苷和非花色苷单体酚类物质等主要品质指标,并对果实品质进行主成分分析。结果表明:两年的甜葡萄总酸含量随产量增大而增加,还原糖含量则随产量增大而降低;2014年花色苷总量表现为L1含量最高,2015年则为L2含量较高,其中基本花色苷总量均表现为L3处理的葡萄含量最低;从两年的非花色苷单体酚类物质总量和黄酮醇类物质含量看,L2葡萄含量最高,其次是L1,L3的葡萄含量最低。结论:主成分分析可看出两年间3 种产量下的甜葡萄分布趋势一致且品质具有差异性,结合两年酚类物质含量看,1 900 kg/667 m2产量下的甜葡萄含量较高。

Abstract: In this study, the spine grape cultivar Tianputao (Vitis davidii Foex.) from Huaihua, Hunan province was used as the experimental material. Three loading levels were set as follows: 1 300 kg/667 m2 (L1), 1 900 kg/667 m2 (L2) and 2 500 kg/667 m2 (L3). The main quality indicators of mature grapes such as total acid, reducing sugar, anthocyanins and non-anthocyanin monomeric phenolics were determined. Principal component analysis (PCA) was carried out on the fruit quality attributes. The results showed that: (1) total acid content increased with loading level for the two crop years 2014 and 2015, while the reducing sugar content decreased; (2) total anthocyanin content was the highest at L1 and L2 for 2014 and 2015, respectively, and the total content of basic anthocyanins was the lowest at L3 for both years; (3) for the two years, the total content of non-anthocyanin monomeric phenolic compounds and total flavonol content were both the highest at L2, followed by those at L1, and L3 gave the lowest values. Furthermore, principal component analysis (PCA) showed that the distribution of Tianputao under the three loading levels was consistent but there was clear discrimination in fruit quality between the two years. For both years, the content of phenols was the highest at L2.
