With the objective of preserving the physicochemical characteristics from green stage harvested of acerola fruits (Malpighia glabra L.), these were submitted to the following 30-minute immersion treatments: control (water), 50mg L-1 GA3, 100mg L-1 GA3, 50mg L-1 BAP (benzylaminopurine), and 100mg L-1 BAP. After treatment, the fruits were air-dried in a cool place and then packaged in styrofoam trays wrapped with polyethylene film, and stored in a BOD incubator at 8°C for 14 days. Evaluations were performed at 4 days intervals. The fruits were evaluated for coloration, soluble solids content, trituratable acidity, and ascorbic acid content. The analysis of the results showed that the application of plant growth regulators did not have effect in the increase of the refrigerated conservation of acerola fruits and that only the cooling was enough to conserve its for 14 days.
