The objective of this study was to evaluate techniques, such as flower-cluster and berry-cluster thinning at different times, to prevent bunch compactness of ?BRS Vitoria?, a new black seedless grape. The experiment was conducted during two consecutive seasons (2013 and 2014) in a commercial vineyard located in Marialva, PR, Brazil. The grapevines were trained in an overhead trellis system, spaced at 2.5 × 5.0 m. The experimental design used was randomized blocks with four replications and six treatments: control (no thinning); flower-cluster thinning or brushing prior to anthesis; and berry-cluster thinning at different times, when berries were 3?6, 7?10, 11?15, or 16?18 mm in diameter. The bunch compactness incidence was evaluated according to the following classification: very loose, medium loose, and very dense bunches. The physicochemical characteristics of bunches and the yield were also evaluated. Data were submitted to analysis of variance, and means were compared using Tukey?s test at 5%. Berrycluster thinning when ?BRS Vitoria? berries are between 7 and 18 mm in diameter is efficient for reducing bunch compactness, as it results in a higher incidence of medium loose and a lower incidence of very dense bunches with optimum yield, while flower-cluster thinning or brushing prior to anthesis should be avoided because it promotes higher incidence of very loose bunches with reduced yield. |
