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

M. Mohammed, J. K. Brecht
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.
