Summary

Golden Delicious apples were treated and stored at 0 deg C for less than or equal to 6 months. Decay caused by B. cinerea after inoculation to a depth of 2 millimeters with a conidial suspension was virtually eliminated in stored fruits heated at 38 deg C, regardless of calcium treatment. Apples punctured to a depth of 0.5 millimeters (but not 2 millimeters) and inoculated with B. cinerea on removal from storage were almost completely protected from poststorage decay if they had pressure infiltrated with 2% calcium chloride, regardless of the heat regime. Heating fruits at 42 deg C and dipping in 2% calcium chloride was only partially effective in preventing decay from either pre- or poststorage inoculations. Fruit firmness was not related to resistance to decay.
