Summary

GRANNY SMITH APPLES HARVESTED OVER 7 WEEKS WERE NOT AFFECTED BY ALCOHOLIC TAINTS AND WERE FIRMER, GREENER AND LESS SUSCEPTIBLE TO SCALD AND CORE FLUSH FOLLOWING STORAGE IN 1.0% CO2 AND 1.5% O2 AT 272.5 K (-0.5 DEG C) AS COMPARED TO PRESENT COMMERCIAL MODIFIED ATMOSPHERE STORAGE AT 3.5% CO2 AND 3.5% O. WITH LOWER STARCH-IODINE INDICES THE INCIDENCE OF CORE FLUSH WAS INCREASED, AND AT HIGHER INDICES THE POTENTIAL FOR SCALD DEVELOPMENT INCREASED SUBSTANTIALLY. EXPOSURE OF FRUIT TO AN INITIAL O2 STRESS AT OR BELOW 0.5% FOR 9 DAYS GAVE ADDITIONAL BENEFITS IN SCALD CONTROL, FRUIT FIRMNESS AND COLOR. IF O2 WAS TOTALLY EXCLUDED BY A 14-DAY TREATMENT WITH CONTINUOUS FLOW-THROUGH OF O2-FREE NITROGEN, CORE FLUSH AND ALCOHOLIC TAINTING INCREASED, BUT SCALD DECREASED.
