In viticulture, choosing the most suitable rootstock for a specific scion cultivar is an efficient and cost-effective way to increase yield and enhance the physicochemical characteristics of the fruit. The objective of this study was to evaluate the agronomic performance of the 'BRS Tainá' grapevine on different rootstocks under the conditions of the Sub-Middle São Francisco Valley. The main experimental factor consisted of eight rootstocks (IAC 313, IAC 572, IAC 766, 101-14 MgT, Paulsen 1103, Ramsey, SO4, and Teleki 5C), arranged in randomized blocks with four replicates. The experiment was conducted over four production cycles, from 2021 to 2023, in a commercial crop area in Petrolina, PE, Brazil. There were significant effects of rootstocks for the yield and number of bunches per plant, as well as berry length and firmness. 'BRS Tainá' achieved the highest yield (22.2 kg per plant) when grafted onto the Paulsen 1103 rootstock, which was superior to the yield on 101-14 MgT, IAC 313, and IAC 572 rootstocks. The highest number of bunches (88) was obtained with 'BRS Tainá' grafted on Paulsen 1103, while the lowest number (63) was obtained on IAC 572; both these rootstocks were not significantly different from the other rootstocks. For all scion-rootstock combinations, the mean values for soluble solid (SS) content, titratable acidity (TA), and the SS/TA ratio were similar to those previously described for 'BRS Tainá', meeting the commercialization standard. The results for the yield and number of bunches per plant indicate the suitability of grafting 'BRS Tainá' on Paulsen 1103 under the semi-arid tropical conditions of the São Francisco Valley.
在葡萄栽培中，为特定的接穗品种选择最合适的砧木是提高产量和改善果实理化特性的一种高效且经济的方法。本研究的目的是在圣弗朗西斯科河谷中下游的条件下，评估“BRS Tainá”葡萄在不同砧木上的农艺性能。主要实验因素包括八种砧木（IAC 313、IAC 572、IAC 766、101 - 14 MgT、保尔森1103、拉姆齐、SO4和Teleki 5C），采用随机区组排列，重复四次。该实验于2021年至2023年在巴西伯南布哥州佩特罗利纳的一个商业作物区进行了四个生产周期。砧木对单株产量、果穗数量以及果粒长度和硬度有显著影响。“BRS Tainá”嫁接在保尔森1103砧木上时产量最高（单株22.2千克），高于嫁接在101 - 14 MgT、IAC 313和IAC 572砧木上的产量。“BRS Tainá”嫁接在保尔森1103上时果穗数量最多（88个），而在IAC 572上最少（63个）；这两种砧木与其他砧木之间差异不显著。对于所有接穗 - 砧木组合，可溶性固形物（SS）含量、可滴定酸度（TA）以及SS/TA比值的平均值与之前描述的“BRS Tainá”相似，符合商业化标准。单株产量和果穗数量的结果表明，在圣弗朗西斯科河谷的半干旱热带条件下，将“BRS Tainá”嫁接在保尔森1103上是合适的。
