Table 3.
Respiration rate (RR) and ethylene production rate (EPR) of Low-impact (30°; 0.074 J), medium (45°; 0.160 J), and high-impact (65°;0.273 J) bruised fruit over 12 days of storage at 5, 13, and 22 °C. Error bars represent the SD of the mean values of 2 readings per treatment. Numerical values of A, B, and C are P-values. All P-values with * symbol are statistically significant. IL; impact level, ST, storage temperature; SD; storage duration.
