| 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... |

| In colored table grapes, the anthocyanin contents are inhibited by the high temperature during ripening and berries suffer a lack of skin color, thus affecting their market value. In order to overcome this issue, a research study was planned to evaluate the influence of (S)-cis-abscisic acid (S-ABA) on rates of anthocyanin accumulation in table grapes when applied at different timings of ripening, and to quantify the gradual increase of berry color. The study was conducted in a commercial vineyard of ?Benitaka? table grapes (Vitis vinifera L.), grown under double annual cropping system in a subtropical area. The trials were carried out during two consecutive seasons (i.e., summer season of 2015 and off-season of 2016). The treatments used for the... |

| 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 berry-cluster thinning technique was evaluated at different phenological times to prevent bunch compactness of ?Black Star? table grape, a new somatic mutation of ?Brasil? grape. The trial was carried out during 2012 and 2013 seaons in a vineyard situated in Marialva, PR, Brazil. Vines were trained in an overhead trellis system and spaced at 3x4m. The randomized block design was used as a statistical model with five replications and five treatments. The following treatments were evaluated: control; brushing prior to anthesis; and berry-cluster thinning at different times, when berries were 3-6, 7-10, or 11-15mm in diameter. The prevalence of bunch compactness was evaluated considering the levels: loose, medium loose, and dense bunches. The main... |

| "BRS Isis" is a new colored seedless table grape tolerant to downy mildew, the main vine disease in subtropical humid areas. This new seedless cultivar is an interspecific hybrid from the crossing of CNPUV 681?29 [Arkansas 1976 X CNPUV 147?3 ("Niagara Branca" x "Venus")] x "BRS Linda", and was recently released by Embrapa Grape and Wine, Brazil. The performance of ?BRS Isis? seedless grape was evaluated in an experimental vineyard in 2016 located in a subtropical area at Marialva city, state of Parana, Brazil. The vines were grafted onto "IAC 766 Campinas" rootstock and trained in an overhead trellising system spaced at 2 × 5 m. Vines were cane-pruning in late winter of July 2016, and for assessments, 20 representative vines were selected in the area. As... |

| 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... |

| The objective of this work was to evaluate cold storage periods and postharvest longevity of the seedless table grape 'BRS Vitória' subjected to the application of the disease-resistance inducer acibenzolarS-methyl (ASM). Bunches were treated or not with 1% ASM, placed individually in plastic clamshell trays and stored in a cold chamber at 2±1ºC, at a high relative humidity, for three periods (30, 45, and 60 days), followed by a 5-day period of shelf life in plastic clamshells, at 22±2ºC. After each storage period, gray mold (Botrytis cinerea) incidence was evaluated, and the physicochemical analysis was performed. A completely randomized design, with four replicates, was used in two 2x3 factorial arrangements: one evaluating ASM application and cold... |

| 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;... |
