Summary

In the first of 2 trials, Queen Victoria pineapples were sprayed with 2-(chlorophenoxy) propionin acid and then induced to ripen with ethylene 37, 53, 67, 81, 93 and 107 days later. Fruits were then harvested and stored at 16 °C to induce blackheart. All control fruits (not sprayed) showed severe symptoms of blackheart as did those sprayed 107 days before harvest. When spraying was applied 37 days before harvest only 11.7% of fruits developed symptoms. In the second trial, a range of step-down temperatures were examined for their effect on blackheart and ripening. Reducing the storage temperature by 3 °C per day from harvesting showed the greatest promise for reducing blackheart.
