Postharvest practices to reduce chilling injury (CI) on eggplants.

The effects of intermittent warming (IW) and high CO2 concentrations during storage on the development of chilling injury in aubergines (cultivars Violetta Lunga, Black Beauty and Sfumata Rosa) are reported. IW (storage for 3 days at 2.5 deg C + 3 days at 12.5 deg + 3 days at 2.5 deg , followed by warming for 3 days at 20 deg ) delayed the appearance of chilling injury symptoms by about a week (compared with control fruits stored at 2.5 deg for 9 days, followed by warming for 3 days at 20 deg ). High CO2 concentrations during storage (5, 8 or 12%) resulted in CO2 injury, characterized by external browning without tissue softening. The spherically-shaped cultivars Black Beauty and Sfumata Rosa were more tolerant of high CO2 concentrations than the long-fruited cv. Violetta Lunga. Sfumata Rosa was most susceptible to storage temperatures <10 deg . Storage quality was best overall in Black Beauty fruits.
