Abstract : Keitt mango fruits (Mangifera indica L.) were harvested at maturity stage, then cold stored at 10+1°C and relative humidity of 85%, for forty days after being subjected to different concentrations of natural compounds known to be physiologically active. In this study, effects of sodium nitroprusside SNP (0.5, 1.0 and 2.0 mM. l-1) a nitric oxide donor, salicylic acid SA (0.5, 1.0 and 2.0 mM. l-1), hydrogen peroxide (H2O2) (10, 20 and 40 mM. l-1) and chitosan (0.5, 1.0 and 2.0%) on cold stored mango fruits were studied. Results revealed that all treatments reduced total sugars, respiration rate, water loss, decay percentage and maintained fruit firmness compared with the control. On the other hand, total soluble solids, titratable acidity, and fruit color showed less response to investigated treatments and concentrations.
