Ethylene production, respiration rates, firmness and Brix values were investigated in attached or detached melon cv. Earl's Seine fruits, in order to study the ripening characteristics and postharvest storage of fruits harvested during spring, summer, autumn and winter seasons. The effects of freshening paper on fruit quality were also examined. There was a gradual increase in ethylene production in fruits attached to the plant as they matured. Both the onset and increase in the rate of ethylene production were accelerated in detached fruits. Ethylene production from fruits harvested 60 days after anthesis reached a maximum (3.5 micro l kg-1 h-1) after 6 days of storage. Brix values for attached and detached fruits were very similar but attached fruits retained their firmness much better than detached ones. The optimum harvesting time was estimated from firmness and soluble solids content. Fruits stored at 20 deg retained a firmness value greater than 350 g after 7 days when harvested in the summer and autumn, but firmness was less than 350 g after 7 days when harvested during winter and spring. Storage at 4 deg resulted in chilling injury after 3 weeks and a decline in firmness to 298 g in 5 weeks for summer-harvested fruits. A small proportion of fruits harvested in winter and spring developed chilling injury at 4 deg , though most of them were of commercial quality after storage for up to 5 weeks. Fruit softening was significantly reduced by using freshening paper during storage at 20 deg for 1 week.
