Factors and time of sample collection for correlating storage potential of 'McIntosh', 'Spartan', and 'Golden Delicious' apples.

The factors associated with storage disorders in 3 commercially important apple cultivars in British Columbia were investigated. Fruit mass, density, N, P, K, Ca and Mg concentrations and dry matter were determined for McIntosh, Spartan and Golden Delicious apples from approx equal to 30 commercial orchards, 9, 6, 3, and 0 weeks before harvest. Storage samples were collected at commercial harvest and evaluated for the development of internal breakdown (McIntosh and Spartan) or bitter pit (Golden Delicious) after 4 and 6 months of air storage at 0 deg C. Mass and Ca concentration and the mass:Ca and K:Ca ratios were the factors most often significantly correlated with storage disorders within each year for all 3 cultivars. Correlations were as frequently significant 6 and 3 weeks before harvest as they were at harvest. The mass of McIntosh and Spartan was consistently related to breakdown in all 3 years of the study. There were no variables with a consistent relationship to bitter pit in Golden D

elicious. Fruit Ca was associated with the relative levels of disorders within years but was not associated with specific levels of disorders across all years.
