Plant growth regulators on the pre-harvest period of 'Pêra' oranges

Plant growth regulators on the pre-harvest period of 'Pêra' oranges

This research evaluated the effects of auxins and gibberellins applied at pre-harvest on the quality of orange juice. Orange trees, Citrus sinensis Osbeck, cv. 'Pêra' were sprayed in three applications, at 45-day intervals, with the following treatments: GA3 + 2,4-D at 12.5mg L-1 each; GA3 + 2,4-D at 25mg L-1; GA3 + 2,4-D at 37.5mg L-1; GA3 + NAA at 12.5mg L-1; GA3 + NAA at 25mg L-1; GA3 + NAA at 37.5mg L-1; NAA + 2,4-D at 12.5mg L-1; NAA + 2,4-D at 25mg L-1; NAA + 2,4-D at 37.5mg L-1, and a control. The treatments did not change juice quality, and showed no plant growth regulator residues 110 days after the last application in every case below 0.05mg L-1.
