Ethylene production in harvested kiwifruit with special reference to ripe rot.

When kiwifruit cv. Hayward fruits were packed in a carton and stored at 20 deg C, some fruits showed ripe rot symptoms and coincidentally started evolving ethylene soon after the transfer from 5 to 20 deg . About 12 days later, the other fruits within the same carton also started evolving ethylene without any ripe rot symptoms. When fruits of 4 cultivars were packed (a) individually in unsealed polyethylene film bags or (b) in polyvinyl chloride (PVC) boxes with an ethylene absorbent to minimize the effect of ethylene evolved from diseased fruits, most sound fruits did not start evolving ethylene until about 60 and 40 days later, respectively. The carbon dioxide in the polyethylene bags or PVC boxes did not accumulate so much as to retard the induction of ethylene synthesis. When sound fruits were stored at 20 deg (separated physically from diseased fruits), they had persistently low internal ethylene concentrations, ACC contents and ethylene forming enzyme (EFE) activity.
