Summary

STARCH INDEX (SI) WAS CORRELATED NEGATIVELY WITH STARCH CONTENT AND POSITIVELY WITH INTERNAL ETHYLENE CONCENTRATION (IEC) AND LOGARITHM TO THE BASE 10 OF IEC (LOGIEC) IN < JONAGOLD > APPLES. THE INITIAL RAPID INCREASE IN SI, LOGIEC, AND YELLOW GROUND COLOUR COINCIDED WITH ONE ANOTHER AND OCCURRED ABOUT 20 DAYS BEFORE THE INCREASE IN IEC AND INCIDENCE OF WATERCORE. FRUIT HARVESTED FROM MATURE TREES STORED WELL AT 273 K (0 DEG C) IN AIR UNTIL FEBRUARY AND IN CONTROLLED ATMOSPHERE (1.5% O2 + 1.5% CO2 ) UNTIL JUN. FRUIT FROM YOUNG TREES WERE LARGE AND DEVELOPED BREAKDOWN (BD) IN AIR AS EARLY AS NOVEMBER ; FRUIT AFFLICTED WITH BD WERE LOWER IN CALCIUM AND HIGHER IN POTASSIUM-CALCIUM RATIO. SENSORY RATINGS WERE HIGHER IN < JONAGOLD > THAN IN < MCINTOSH >, < GOLDEN DELICIOUS >, < SPARTAN >, AND < DELICIOUS > AND WERE ALSO HIGHER IN FRUIT FROM CONTROLLED ATMOSPHERE THAN FROM AIR STORAGE.
