The trial was carried on throughout two harvest seasons (2001–2002), in the Bebedouro Experimental Field, Embrapa SemiÁrido, Petrolina-PE, Brazil. The trial was laid out in a randomized complete block design with three replicates, each replicate consisting of a four-tree plot. The treatments were: one level of gibberellic acid split in five applications (10 + 15 + 15 + 50 + 50 mg.L-1), two levels of Crop Set (0.1 and 0.2%) and trunk girdling, isolated or combined with the other treatments. In 2001, the maximum values for weight, length and diameter of berry were observed with girdling + gibberellic acid and girdling + gibberellic acid + Crop Set at 0.1% treatments. The treatments girdling and Crop Set when applied isolated and/or combined to each other did not increase the berry size. In 2002, the treatments girdling + gibberellic acid and girdling + gibberellic acid + Crop-Set at 0.2% promoted larger berries, increasing berry length by 32%.  aGibberellic acid  aGirdling  aGrapes  aSeedless varieties  aÁcido Giberélico  aUva  aVitis Vinifera  aAnelamento  aBioestimulante  aCitocinina  aCrop Set  aUva sem semente  aVale do São Francisco1 aSILVA, D.
