dc.descriptionThe new ‘BRS Melodia’ table grape cultivar has attracted the attention of consumers due to the pleasant taste of a mix of red fruits and pink color. This study aimed to determine the ideal gibberellic acid concentration associated or not with plant biostimulants, aiming to improve the physical and physicochemical characteristics of ‘BRS Melodia’ grapes in the Submédio São Francisco Valley. Two experiments were conducted in a commercial vineyard located in the municipality of Petrolina, PE, Brazil. In the first experiment, treatments were represented by eight gibberellic acid concentrations (GA3) (12.5; 13; 17.5; 18; 22.5; 23; 27.5 and 28 mg.L-1), while in the second experiment, three GA3 concentrations (13, 18 and 30 mg.L-1) were used, associated or not with biostimulants. In both experiments, control did not receive GA3 and biostimulants. The evaluations of the physical and physicochemical variables of bunches and berries were carried out during two consecutive production cycles, 2021 and 2022. The experimental design was in randomized blocks with four replicates. Treatments used in experiment 1 did not provide significant gains in the characteristics of bunches and berries. In the second experiment, biostimulant A (Benzyladenine 2%) associated with 30 mg.L-1 of GA3, divided into three applications (8 mg.L-1 + 10 mg.L-1 + 12 mg.L) prom-1oted increments in variables berry mass and length. These growth regulators should be used to promote the growth of ‘BRS Melodia’ berries in the Submédio São Francisco Valley.
