Summary

WAXING THE FRUIT AND CROWN OF FRESH PINEAPPLE WITH A 20% V/V PARAFFIN-POLYETHYLENE/WATER MIXTURE REDUCED THE INCIDENCE AND SEVERITY OF INTERNAL BROWNING CAUSED BY CHILLING INJURY TO 15% AND 31%, RESPECTIVELY, OF THE UNWAXED CONTROL. SYMPTOM INCIDENCE IN WAXED FRUIT WAS NOT AFFECTED BY FRUIT MATURITY AT HARVEST. INCREASING WAX/WATER EMULSION CONCENTRATION UP TO 50% V/V FURTHER DECREASED SYMPTOM INCIDENCE AND SEVERITY WITH THE GREATER SUPPRESSION OCCURRING WITH LESS THAN 20% V/V. CROWN LEAVES WERE EXTREMELY SUSCEPTIBLE TO CHILLING INJURY. WAXING ASSISTED IN RETAINING FRUIT SHELL APPEARANCE AND REDUCED THE RATE OF SHELL DEGREENING BY 60%. THE MAJOR CHANGES OCCURRED DURING HOLDING AT ROOM TEMPERATURE FOLLOWING 281 K (8 DEG C) STORAGE.
