Abstract

‘Empire' apples were stored at 0 °C or 3 °C with 0.03 or 5 kPa CO2 and 2.5 kPa O2 for 16 wk. Pools of free, soluble conjugated and bound putrescine, spermidine, and spermine fluctuated in a dynamic manner in response to both temperature and CO2. These results suggest that putrescine homeostasis is under different regulatory control than spermidine/spermine homeostasis.
