Resumo: | The aim of the present work was to evaluate the effects of auxins and gibberellins when applied at pre-harvest to the fruit development, and to the ripening and natural fall of the fruit, in 'Pêra' oranges. Trees of Citrus sinensis Osbeck cv. Pêra, 5 years old, were utilized. The treatments applied were: GA3 + 2,4-D 12.5mg L-1 of each; GA3 + 2,4-D 25mg L-1 ; GA3 + 2,4-D 37.5mg L-1; GA3 + NAA 12.5mg L-1; GA3 + NAA 25mg L-1; GA3 + NAA 37.5mg L-1; NAA + 2,4-D 12.5mg L-1; NAA + 2,4-D 25mg L-1; NAA + 2,4-D 37.5mg L-1; and water (control). The treatments were applied 3 times, at intervals of 45 days. The variables evaluated were: rate of natural fall (%), fruit length and diameter (mm), and fresh fruit weight (g). None of the treatments promoved alterations in the development of the fruits, but they did reduce the natural fall rate, when compared to control, up to 78.05%, inhibiting the fruits' abscision as much as 3 months.
