Commercial potential for increasing apple tissue calcium sufficiently to maintain fruit quality in storage.

ABSTRACT :

 

Apple trees (Golden Delicious or Delicious) were sprayed at intervals throughout the growing season with CaCl2 solutions or pressure-infiltrated after harvest at a commercial packing and storage facility. The tissue Ca concentration of fruits from sprayed trees was significantly increased but not enough to potentially retard decay by pathogens infecting wounded fruits or to maintain fruit firmness. Pressure-infiltrating fruits postharvest with higher concentrations of CaCl2 (4-8%) resulted in fruit tissue Ca concentrations which would potentially retard decay and maintain firmness. However, inadequate Ca uptake is a problem with some fruits, while excessive Ca uptake, resulting in injury, is a problem with others. Proper sanitation to reduce fungal infection due to the pressure-infiltration procedure must also be implemented before CaCl2 pressure-infiltration can be seriously considered for commercial use.
