In 1993-94, Red Delicious apple fruits harvested 143 days after full bloom were dipped in 4 or 8% CaCl2 for 10 min then stored at 0 deg C for 6 months. Fruits from trees on M.9 rootstock produced more ethylene during storage than those from trees on M.26. CaCl2 treatments decreased ethylene production and delayed the production peak. Fruits from trees on M.9 were more permeable to CaCl2 than those from trees on M.26. There was a positive correlation between fruit firmness and CaCl2 concentration. After 6 months of storage the dry matter content and mealiness of fruits from trees on M.26 were greater than those of fruits from trees on M.9. Total soluble solids content was greater in fruits from trees on M.26 than in those from trees on M.9, but titratable acidity and pH were not affected by rootstock or by CaCl2 concentration.
