Summary

Kiwifruit develop physiological disorders when stored at or below 0°C. As symptoms are only evident after long term storage, this study aimed at investigating the possibility of reducing chilling injury by temperature switching during storage. ‘Hayward’ and ‘Zesy002’ kiwifruit of different maturities were subjected to dual temperature treatments by switching fruit from either 0 or 2°C to 2 or 0°C, respectively, at different times in storage. Initial storage of ‘Hayward’ at 0°C and later switching to 2°C resulted in a lower proportion of soft fruit and reduced chilling injury incidence. ‘Zesy002’ was more resistant than ‘Hayward’ to chilling injury. Tolerance to chilling injury was related to maturity at-harvest. After 150 d in storage, a sudden decline in firmness was observed in ‘Hayward’ kiwifruit stored continuously at 0°C, but not in the dual temperature treatments. Proportion of soft fruit was correlated with chilling injury incidence.
