| The application ofS-ABA enantiomer to clusters of poor pigmentation cultivarscan improve grape color. The aim of this study was to assess whetherS-ABA applied toclusters of the new hybrid ?BRS Melodia? seedless grape can improve its colorcharacteristics and to evaluate the consumer acceptance. The following treatments wereevaluated: Control;S-ABA at 200 mg·LL17 days after veraison (DAV);S-ABA at 400mg·LL17 DAV;S-ABA at 200 mg·LL17 DAV+200 mg·LL121 DAV; andS-ABA at 400mg·LL17 DAV+400 mg·LL121 DAV. To apply the treatments, clusters were sprayedusing a backpack sprayer until runoff. The exogenous application ofS-ABA significantlyimproves the color of berries of ?BRS Melodia? seedless grape, particularly at aconcentration of 400 mg·LL1in two applications, at 7... |

| 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... |

| The development and evaluation of new cultivars of seedless grapes (Vitis spp.) with good yield and adapted to different edaphoclimatic conditions are essential to increase the competitiveness of the productive system. The present work had the objective to characterize the phenology and the yield of the new hybrid seedless grape ?BRS Melodia?, grown in an annual double cropping system in a subtropical region. The evaluations were carried out during the 2013 summer cropping period and the 2014 off-season cropping period in a commercial area located in Marialva, PR, Brazil. The ?BRS Melodia? scions were grafted onto ?IAC 766 Campinas? rootstocks, trained in an overhead trellis system spaced at 2.5 × 2.5 m. In both seasons, the duration in days of the main... |

| A amora-preta (Rubus spp.) destaca-se entre as espécies que apresentam boas perspectivas de cultivo em áreas de agricultura familiar. Visando a otimizar a multiplicação de mudas dessa espécie, o objetivo deste trabalho foi avaliar o uso de substratos e concentrações do ácido indolbutírico (AIB) no enraizamento de estacas de amora-preta Xavante. O delineamento experimental foi o inteiramente casualizado em arranjo fatorial 3x2 (três tipos de substratos e duas concentrações de AIB), com cinco repetições de sete estacas, sendo adotados os fatores: tipos de substratos (casca de arroz carbonizada, vermiculita grânulos médios e fibra de coco) e tratadas ou não com AIB (0 e 1000mg L-1). Após 80 dias, foram avaliadas as variáveis: sobrevivência das estacas;... |
