QUALIDADE DA UVA 'SUPERIOR SEEDLESS' COM APLICAÇÕES DE BENZILADENINA COMBINADAS OU NÃO COM ÁCIDO GIBERÉLICO

Abstract

In the handling for the quality of grapes without seeds the use of gibberellic acid (GA3) in association with synthetic cytokinin of character is common not purics derivatives of the urea, being the most common TDZ (N-fenil-N-1,2,3-Thidiazol-5-il urea) and the CPPU (n (2-chlorine-4-pridil) - N-feniluréia). The present work had for objective to study the effect of the cytokinin of character purics: BAP (6-benzilaminopurina), associate with the gibberellic acid (GA3), in clusters of the cv. Superior Seedless, in the Valley of the San Francisco. The evaluated characteristics had been the mass fresh weight (g), diameter (mm), length (mm) and volume of berries (mL), soluble solid (SS), titratble acidity (AT) and relation SS/AT. It was verified that the GA3 in the concentration of 10 mg.L-1 associated with 10 mg.L-1 and 20 mg.L-1 of BAP had promoted the increments most significant in the quality of clusters of the cv. Superior Seedless.
