Conteúdo: | This work was carried out in a 4-year old mango orchard, cultivar ?Tommy Atkins?, in a semi-arid region of the Bahia State, Northeast Brazil (?Iaçu Agropastoril? Corporation). To evaluate the effect of paclobutrazol (PBZ) on flowering and fruit set, four doses of PBZ (0.0; 0.5; 1.0 and 1.5 g per meter of canopy diameter) were applied, via soil, to 24 plants for each dose. Flowering and fruit set percentage, fruit production, and inflorescence compaction were evaluated. Five flowering evaluation were performed: at 98, 103, 112, 119, and 130 days from PBZ application (done on 26-May-2000). Percentage of fruit establishment was evaluated after 166 days and fruit production at the harvest time, 208 days after PBZ application. Results showed that PBZ, in all levels, promoted an increase of flowering percentage in relation to control. The flowering varied from 76% (with 0.5 g/m of PBZ) to 88% (with 1.5 g/m), while in the control the flowering was only 35%. PBZ caused an inflorescence compaction in a degree proportional to the PBZ doses. Fruit establishment also increased with PBZ for all levels, varying from 38% to 42%, which was significantly higher than control (10%). All PBZ levels promoted statistically similar fruit production (average of 57 kg/plant), significantly higher than control (34 kg/plant).
