Influence of climate, harvest maturity, waxing, O2 and CO2 on browning disorders of 'Braeburn' apples.

Braeburn apple fruits (harvested in British Columbia, Canada in 1993-1996) stored for 6 months in controlled atmosphere storage (CA; 1.2-1.5% O2 + 1.0-1.2% CO2) at 0 deg C were 8 N firmer, had 20% higher titratable acidity, and had markedly less brown core than fruits stored in air. Fruits held in CA were, however, susceptible to Braeburn browning disorder (BBD) and internal CO2 injury (ICI) after cool growing seasons. Results of various trials indicated that advanced harvest maturity and storage in a high CO2 and low O2 atmosphere (3.0 CO2 + 1.5% O2) increased both BBD and ICI, and that application of Shellac wax to late-harvested fruits 15 days after harvest increased BBD after storage in air for one month but had no effect on ICI. Storage temperature (3.0, 1.7 or 0 deg ) had no consistent effect on BBD and had no effect on ICI in CA-stored fruits.
