'Anjou' pears (Pyrus communis, L) were subjected to seven different control
led atmosphere (CA) storage practices and stored at 1C, for 90, 150 or 210
days plus 30 days at regular air atmosphere (RA). CA storage treatment cons
erved pear qualities to a certain extent regardless of storage treatment Es
tablishment of CA conditions (2% O-2 and <1 % CO2) on warm pears (20C), pri
or to cooling, resulted in reduced firmness, finish and color and increased
amount of scald, shrivel and physiological disorders. Pears held in CA sto
rage (2% O-2 and <1 % CO2) for 90 days and an additional 30 days in RA stor
age maintained good quality. When held for longer storage periods, firmness
, finish and color decreased, and scald, shrivel and physiological disorder
s increased.
