High-performance preharvest treatments can ensure maintenance of quality during storage. In this study, gibberellic acid (GA(3)) was applied on the trees in the preharvest stage to study its effects on the storage potential of the 'Angelino' plums. The treatment was applied at 50 and 75 mg/L concentrations, on the 8th, 10th, 12th and 14th 'week after anthesis' (WAA). The results of the GA(3) applications on the 'Angelino' plum quality after 90 days of storage and an additional 2 days of shelf life showed a decrease in weight loss, with a corresponding increase in fruit flesh firmness, total soluble solids and titratable acidity with the treatment. The fruit skin hue values were higher in the GA(3) treated plums, whereas no change was observed in the total antioxidant activity and total phenol contents. Overall, the effect of the preharvest GA3 application on the 'Angelino' plum quality during storage at 0 +/- 0.5 degrees C and 90-95% relative humidity for 90 days was positive.
