Summary

DELICIOUS APPLES WERE PRESSURE-INFILTRATED (68.95 KILOPASCALS) ABOVE ATMOSPHERIC AT HARVEST WITH CALCIUM CHLORIDE, MAGNESIUM CHLORIDE, OR STRONTIUM CHLORIDE. AFTER 5 MONTHS AT 273 K (0 DEG C), THE FRUIT WERE WOUND-INOCULATED WITH A CONIDIAL SUSPENSION OF PENICILLIUM EXPANSUM, AND KEPT FOR 7 DAYS AT 293 K (20 DEG C). FRUIT THEN WERE RATED FOR DECAY SEVERITY, ETHYLENE PRODUCTION, RESPIRATION, FIRMNESS, AND INJURY. CALCIUM WAS THE OPTIMUM CATION FOR REDUCING DECAY, MAINTAINING FRUIT FIRMNESS,AND SUPPRESSING ETHYLENE PRODUCTION. MAGNESIUM WAS THE ONLY CATION THAT CAUSED DISTINCTIVE INJURY TO THE FRUIT SURFACE.
