Summary

IN RELATION TO TEMPERATURE, THE RESULTS INDICATED CONSIDERABLE VARIATIONS IN CHILLING INJURY AS WELL AS IN ETHANOL, ACETALDEHYDE AND ETHYLENE PRODUCTION ; ROT DAMAGE, HOWEVER, WAS NEGLIGIBLE. AT 275 K (2 DEG C) DETERIORATION WAS GREATER, DUE TO HIGH METABOLIC PRODUCTION IN THE JUICE AND SEVERE CHILLING INJURY, WHILE AT 288 K (15 DEG C) RESPIRATORY RATES AND ETHYLENE PRODUCTION WERE HIGHER. THE OPTIMUM TEMPERATURE PROVED TO BE 280 K (7 DEG C), BOTH FOR HEALTHINESS AND QUALITY OF THE FRUIT. ETHYLENE PRODUCTION WAS ONLY OBSERVED IN FRUITS STORED AT 288 K, AND WAS CORRELATED TO THE PERCENTAGE OF ROTTING AND RESPIRATORY RATE.
