Abstract ‘Marsh’ grapefruit ( Citrus paradisi Macf.) were seal-packaged in low-density, polyethylene films ranging from 20 to 40 µm in thickness and stored at temperatures from 5 to 28°C for periods up to 109 days. Film thickness had a negligible effect on transpiration, respiratory gas exchange, and juice quality. Storage temperature had a negligible effect on transpiration of seal-packaged fruit. However, 28° storage temperature significantly affected acid concentration in both seal-packaged and unwaxed fruit, probably as a result of increased respiratory activity at high storage temperatures. Quality of both seal-packaged fruit and unwaxed fruit deteriorated in storage at 28°.
