Abstract : Mature fruits of mango cv. Amrapali were harvested on 4 July 1993, and treated with gibberellic acid (GA3) at 50 ppm, bavistin [carbendazim] at 500 ppm, or 200 gauge perforated polyethylene (20% vent) bag (alone or in combinations) and kept under ambient temperature (from 33 + 2°C to 37 ± 2°C) conditions. The physiological loss in weight (PLW) progressively increased as the storage period advanced. On the eleventh day of storage, PLW was maximum (18.53%) under the control and minimum (7.48%) in GA3 + polyethylene bag treatment. Higher percentage of total soluble solids (TSS) and reduced level of titratable acidity were recorded in all the treatments up to the last day of storage. Fruits treated with GA3 + perforated polyethylene bag had the lowest acidity (39.84%) and highest TSS (22.15%). The highest TSS/acid ratio was observed in the control (113.67%) whereas GA3 + perforated polyethylene bag showed the lowest ratio (69.46%).
