We studied the effects of gibberellic acid and 2-hydroxymethyl-4-chlorophenoxyacetic acid on bunches of bananas cultivar 'Nanicâo'. Applications of several concentrations of the chemicals isolately or in combination, were realized in the total bunch or in the last two hands (clusters) of the bunch. The sprays were applied in the moment of development of the last hand of the bunch. The treatments do not change the following parameters: length of the medium fruit (finger) of the bunch, length of the medium fruit of the next to last hand, and the weight of fruits of the last two hands of the bunch.
