Changes in the ultrastructure of the epicuticular wax and postharvest calcium uptake in apples.

Golden Delicious apple fruits were non-treated or pressure infiltrated with distilled water or with 0.14 or 0.27 mol CaCl2/litre 2 weeks before optimum harvest time, at optimum harvest, or after 2, 4 or 6 months of storage at 0 deg C. Examination of the fruit surface with low-temperature scanning electron microscopy revealed that cracks in the epicuticular wax became wider and deeper as storage duration increased. After 6 months of storage, the cracks extended through the cuticle. Uptake of Ca by the infiltrated fruits was greater after 6 months of storage than after shorter storage intervals. The data indicate that as storage duration increased, epicuticular wax cracks became deeper and Ca uptake by the fruits increased.
