| 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... |

| "BRS Isis"is a new colored seedless table grape tolerant to downy mildew, the main vine disease in subtropicalhumid areas. This new seedless cultivar is an interspecific hybrid from the crossing of CNPUV 681-29 [Arkansas1976 × CNPUV 147-3 ("White Niagara"×"Venus")] ×"BRS Linda". However, its performance under subtropicalconditions hasn ́t been assessed yet, especially under double annual cropping system. For this purpose, a re-search was designed with the objective to characterize the phenology and the main physicochemical propertiesof this new cultivar. The trial was carried out in a commercial vineyard of?BRS Isis?seedless grape from 2-year-old vines grafted on?IAC 766 Campinas?rootstock, located in Marialva, state of Paraná (PR), Brazil, in... |
