Abstract ‘Spartan’ apples were dipped in 4% CaCl 2 solution after harvest. One week after treatment, the Ca concentration was 19 ppm higher at the 0–2.5 mm depth in the flesh of the dipped fruit. After 2 weeks, Ca was 41 ppm higher at the 0–2.5 mm depth and 26 ppm higher at the 2.5–5.0 mm depth. After 4 weeks, Ca was 36 ppm higher at the 2.5–5.0 mm depth, 25 ppm higher at the 2.5–5.0 mm depth and 16 ppm higher at the 5.0–7.5 mm depth. After 8 weeks, Ca was 68, 49, 43, 36, 30, 24, 27 and 27 ppm higher at 8 successive 2.5 mm depths. After 32 weeks, Ca was 84, 70, 62, 62, 61, 58, 62 and 62 ppm higher at the 8 successive depths in the dipped fruit.
