Summary

THE POSTHARVEST BEHAVIOUR OF WATERMELON HARVESTED AT SELECTED STAGES OF DEVELOPMENT AND STORED IN AIR OR EXPOSED TO 50 MICROLITERS ETHYLENE/LITER OR 6,500 MICROLITERS PROPYLENE/LITER WAS INVESTIGATED. ETHYLENE TREATMENT INDUCED A RAPID DETERIORATION OF FRUIT. MELONS OF ALL MATURATION STAGES HELD IN AIR SHOWED LITTLE TEXTURAL CHANGE THROUGHOUT STORAGE AND PRODUCED ONLY TRACE QUANTITIES OF ETHYLENE. RESPIRATORY ACTIVITY WAS ENHANCED IN THE PRESENCE OF ETHYLENE OR PROPYLENE AND RETURNED TO NORMAL RATES UPON REMOVAL F GAS. ETHYLENE PRODUCTION WAS NOT INITIATED BY EXPOSURE OF FRUIT TO PROPYLENE, AND WAS DETECTED ONLY IN FRUIT EXHIBITING SYMPTOMS OF DECAY. THE RESULTS SUPPORT THE CONCLUSION THAT WATERMELON FRUIT EXHIBIT A NONCLIMACTERIC PATTERN OF RIPENING.
