摘要

'Itália' grape (Vitis vinifera L.) is one of the main varieties for fresh market in Brazil. Cluster quality is determinant for commercialization and the berry size is highly valued by consumers. An alternative for improving berry size is the use of growth regulators. The effect of increasing concentrations of gibberellic acid (GA3) and forchlorfenuron (CPPU) applied alone or in mixtures was evaluated during three production cycles. Growth regulators were applied 25 days after flowering in the "pea berry size" phenologic stage. Experimental design was completely randomized 4x4 factorial (zero, 10, 20 and 30 mg L-1 GA3 X zero, 5, 10 and 15 mg L-1 CPPU) with eight replications for the first cycle, and 3X3 factorial (zero, 20 and 30 mg L-1 GA3 X zero, 10 and 20 mg L-1 CPPU) with ten replications for the others cycles. The application of GA3 at 20 mg L-1 associated with CPPU at 10 mg L-1 improved berry size without affecting cluster mass, leading to higher grape quality in Porto Feliz, SP. CPPU single application reduced total soluble solids content of the berries.
