Efficient techniques as the floral induction allow the establishment of commercialization strategies for favorable periods of market and economical success in the cultivation of mango fruits. An experiment, was conducted in order to study the effect of different paclobutrazol doses (PBZ) on the flowering and production of mango fruits Cv. Rosa. The experiment design used was formed by randomized blocks with four treatments with five replications. The treatments were composed of: T1-control (only water); T2- PBZ- 0,40g a.i./m canopy; T3- PBZ- 0,80g a.i./m canopy; and T4. PBZ- 1,20g a.i./m canopy. The evaluation consisted of the following characteristics: flowering anticipation, number and fruits production per plant. The obtained results were submitted to regression analysis and Dunnet test. It was observed a higher percentage of flowering and fruit production for T2 (0,40g) T3 (0,80g) and T4 (1,2g) in comparison to the Control. The PBZ treatment also anticipated flower initiation and fruit harvest, what means production out of season higher prices and more profitability.
