Résumé

Effects of postharvest pressure infiltration of distilled water, calcium chloride solutions at 0.14 or 0.27 mol/litre with or without subsequent fruit coating treatments of preclimacteric Golden Delicious apples on volatile levels, respiration, ethylene production and internal atmospheres after storage at 0 °C for 1-6 months, and during subsequent shelf life at 20 °C were investigated. Pressure infiltration with water and increasing concentrations of calcium chloride resulted progressively in reduced total volatile levels, respiration, ethylene production and internal O2 levels and increased CO2 levels in fruits following 2-4 months' storage in air at 0 °C. Following the calcium treatments with a coating had similar but stronger and more persistent effects on volatile levels, respiration, ethylene production, and internal atmospheres. Results suggest that pressure infiltration inhibited volatile levels, respiration and ethylene production by forming a barrier to CO2 and O2 exchange between the fruit tissue and the surrounding atmosphere.
