Summary

REGRESSION EQUATIONS WERE DEVELOPED FROM SEASONAL LEAF AND FRUIT MINERAL ANALYSES TO PREDICTQUALITY PARAMETERS FOR < STARKSPUR GOLDEN DELICIOUS > APPLE. QUALITY PARAMETERS WERE EVALUATED BOTH AT HARVEST AND AFTER 6 MONTHS OF 273 K (0 DEG C) STORAGE. SOLUBLE SOLIDS, SKIN GROUND COLOUR, AND TITRATABLE ACIDITY WERE STRONGLY PREDICTABLE AS EARLY AS JUNE OR JULY. FOR TITRATABLE ACIDITY, A COMBINATION OF BOTH LEAF AND FRUIT MINERALS PRODUCED STRONGER PREDICTIONS THAN LEAF OR FRUIT MINERALS ALONE IN EACH INDIVIDUAL YEAR. SOLUBLE SOLIDS, SKIN GROUND COLOUR, AND BITTER PIT WERE MORE ACCURATELY PREDICTED BY FRUIT ANALYSES. FRUIT SIZE WAS IMPORTANT IN REGRESSION EQUATIONS FOR FIRMNESS.
