Qualification of 'Bordô' grape clones in Vale do Rio do Peixe, in the state of Santa Catarina, Brazil

Abstract: The objective of this work was to characterize the productive and qualitative performances of 11 clones of 'Bordô' grape (Vitis labrusca) destined to wine and juice production, in the region of Vale do Rio do Peixe, in the state of Santa Catarina, Brazil. The experiment was carried out in the 2011, 2012, 2014, and 2015 crop seasons. The analyzed yield components were: number of clusters per vine, yield, cluster weight, accumulated yield, and alternate bearing index. The analyzed morphological characteristics of clusters were: number of berries per cluster, berry diameter, cluster compactness index, and cluster length. In order to assess grape quality, the following parameters were analyzed: soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, total anthocyanins, and total polyphenols. The 'Bordô' grape clones 13 and 16 ('Paco' and 'Bocaina') are the most suitable ones for cultivation in the wine producing region of Vale do Rio do Peixe, as they show the highest yields, production stability, and grapes with adequate quality for wine and juice elaboration.

摘要：本研究旨在表征巴西圣卡塔琳娜州佩谢谷河（Vale do Rio do Peixe）产区11个用于酿酒与果汁生产的‘波尔多’（Bordô）葡萄（美洲葡萄Vitis labrusca）无性系的生产与品质表现。实验于2011、2012、2014及2015年作物生长季开展。本研究测定的产量构成要素包括：单株果穗数、产量、果穗重量、累计产量及隔年结果指数（alternate bearing index）；果穗形态特征包括：单穗果粒数、果粒直径、果穗紧密度指数（cluster compactness index）及果穗长度。为评估葡萄品质，分析了以下参数：可溶性固形物（soluble solids, SS）、pH值、可滴定酸度（titratable acidity, TA）、SS/TA比值、总花青素及总多酚。结果显示，‘波尔多’葡萄无性系13号与16号（对应品种名分别为‘帕科’Paco与‘博卡伊纳’Bocaina）是该产区最适宜的栽培无性系，其不仅产量最高、生产稳定性最佳，且所产葡萄具备酿酒与果汁酿制所需的合格品质。
