| Abstract:
‘Conference’ pears were stored for 120, 150, 180, and 210 days in a standard cold store at 0°C and in a CA store. Ripening was conducted for 6 days at a constant temperature of 18°C or 10°C for the first 3 days and at 20°C for the subsequent 3 days. Pears from the standard cold store and from CA containing 0 % CO2 + 2 % O2 and ripened at 10°C, acquired the acceptable ripeness after 3 and 4 days, respectively. Pears from CA storage of 2 % CO2 + 2 % O2 or 3 % CO2 + 5 % O2 and ripened at the same temperature preserved the firmness within 1.5 – 2.0 kG. Lower ripening temperatures slowed firmness losses and metabolic changes, permitting a considerable extension of the marketing period. | |
