Abstract : Kitt mangoes were used to investigate the effects of salicylic acid (0.5 mM, 1.0 mM) and ethanol vapor at 25% for 8 hr. treatments on the quality characteristics during 2011 and 2012 seasons. After treatments, fruits were stored at 5°C with 90% RH for 7 days followed by ripening (market conditions) at 20±2°C for 10 days. At certain intervals, samples were collected from each treatment for physical and chemical analysis (e.g. visual chilling injury symptoms, discarded fruits, weight loss, fruit firmness, total soluble solids, titratable acidity, solute leakage, ethylene production and respiration rate). Salicylic acid at 1.0 mM and ethanol vapor treatments reduced severity of chilling injury, solute leakage, discarded fruit and weight loss percentage. Also, these treatments gave the highest values of fruit firmness T.S.S and these treatments were effective in minimizing respiration rate gradually during cold storage which acquire the fruits the chilling injury tolerance.
