Breaker tomatoes of the long life cultivar ‘Daniela F-1’ Hazera (Lycopersicon esculentum Mill) treated with 1 g/L iprodione, were stored at 6, 9 and 12 °C, and 90–95% RH for 14 and 21 d. Fruit stored at 6 and 9 °C was exposed to intermittent warming at 20 °C for one day, at 7-d intervals. Fruit was then allowed to ripen for a period of 3 d at 20 °C and 75–80% RH. In comparison to continuous storage at 6 or 9 °C, intermittent warming during two or three cycles of 6 d at 6 or 9 °C and 1 d at 20 °C, enhanced the surface colour and encouraged ripening. At the end of cold storage and after post-storage ripening, there was no significant change in the soluble solids content. A slight reduction in titratable acidity was induced by intermittent warming. After ripening, the best results were obtained by intermittent warming during three cycles of 6 d at 9 °C and 1 d at 20 °C. Continuous storage at 12 °C also yielded good results. Both treatments resulted in fruits of acceptable quality and shelf life for commercial purposes. Similar results have already been reported for conventional tomato hybrid plants, indicating that the physiological behaviour of both cultivars were similar under similar intermittent storage temperatures.
