Panels a-d represent time-course profiles for putrescine, spermidine, spermine and total polyamines, respectively. Storage conditions: 0 °C, 2.5 kPa O2 and 5 kPa (●) or 0.03 kPa (○) CO2. All the data represent the mean of four treatment replicates, each being the average of three to four subsamples. The error bar above 0 wk represents the least significant difference at the P ≤ 0.05 level. Note that the y-axis varies among the panels
