INFLUENCE OF ETHYLENE TREATMENTS ON RIPENING AND CHILLING INJURY ALLEVIATION IN MANGO (CV. PALMER) FRUIT

The effect of exogenous application of C₂H₄ on fruit ripening processes to alleviate chilling injury (CI) in mango (cv.
Palmer) fruit was investigated.
Half-mature fruits were either placed in air at 20°C for 2 days or exposed to 100 ppm C₂H₄ for 2 days at 20°C and evaluated for physiological and sensory quality attributes at 3-day intervals up to 15 days at 5°C. After 15 days at 5°C fruits were transferred for 1 and 3 days at 20°C to determine the manifestations of CI.

Exogenous C₂H₄ applied at 100 ppm for 1 day at 20°C plus 1 day in air did not initiate the climacteric but prevented CI in fruit during 15 days at 5°C plus 1 or 3 days at 20°C. A 2-day C₂H₄ treatment, initiated climacteric C₂H₄ and CO₂ production and though effective in reducing CI, resulted in 10.6% fruit decay.
Meanwhile, fruits exposed to air at 20°C for 2 days before storage for 15 days at 5°C plus 1 or 3 days at 20°C remained preclimacteric and developed moderate symptoms of CI.
