Summary

Samples of the apple cultivars Gala, Fuji and Lady Williams were picked over a three week period and stored under controlled atmosphere conditions (1.5% O2 at 0-1 deg C). Samples were removed for analysis at 0, 3 or 4, 5, 7 and 9 months. Ethylene production rates were measured at harvest, and internal ethylene levels after various storage intervals. Firmness was assessed at harvest and after 7 and 9 months of controlled atmosphere storage and 18 or 25 days at 20 deg C, Gala and Lady Williams cultivars showed climacteric ethylene patterns with ripening, but this was much less obvious with the cultivar Fuji. Gala apples maintained a higher level of firmness if put into controlled atmosphere storage in a preclimacteric state. For the other cultivars, edible quality after controlled atmosphere storage was much less affected by pick date.
