The possibility of combining four strategies known to be effective in delaying the onset of internal breakdown (wooliness) of peaches and nectarines (cultivars Flamekist and Fairlane) in order to obtain a maximum storage life of 6-8 weeks, under commercial conditions was examined. Nectarine plots were sprayed with 70 ppm GA3 at the end of pit-hardening. Half of the bins harvested from the treated and control plots were stored at 0 deg C on the day of harvest, and the second half were held at ambient conditions for 36 h prior to cold storage (delayed storage). The cooled fruit was stored in two controlled atmosphere (CA) rooms (5% O2+8% CO2), with either ethylene removal or addition (100 ppm). Fruit quality parameters were examined after 4-6 weeks upon removal from CA after an additional week in regular atmosphere at 0 deg C for 7 days and after 5 days shelf life at 20 deg C. The external appearance of the fruit was acceptable up to 7 weeks storage in all treatments, without delayed storage, where the fruit showed excessive weight lass and some shrivelling. The internal quality of CA-stored fruit, its juiciness and taste were improved by the GA3 treatment. The addition of either ethylene or delayed storage was of additional benefit, but there was no added advantage to the combination of all four factors.
