ETIOLOGY AND CONTROL OF MUCOR ROT IN COLD-STORED APPLES.

Author(s) : COMBRINK J. C., GROBBELAAR C. J.

Summary

THE AUTHORS DETERMINED THE FREQUENCY OF MUCOR SPORES IN DUMP TANK WATER, THE PATHOGENICITY OF VARIOUS SPORE CONCENTRATIONS, THE OPTIMUM CONTAMINATION TEMPERATURE, THE MODE OF INFECTION AND THE EFFICACY OF CHLORINE. THEY FOUND SPORES IN FEW DUMP TANKS, IN RELATIVELY SMALL NUMBERS. AT 297 K (24 DEG C), PATHOGENICITY DID NOT INCREASE WITH THE INCREASE IN SPORE CONCENTRATION. CONTAMINATION OCCURRED AT 272.4 K (-0.6 DEG C), BUT NOT AT 303 K (30 DEG C). IT IS OPTIMUM FOR STARKING, GOLDEN DELICIOUS AND GRANNY SMITH APPLES AT 278.5, 278.5 AND 293 K (5.5, 5.5 AND 20 DEG C), RESPECTIVELY. CHLORINE CONSIDERABLY REDUCES THE NUMBER OF SPORES.
