Abstract: A post-harvest trial was conducted to determine the respiratory behaviour and its influence on shelf-life of pomerac (Eugenia malaccensis) held at four different storage temperatures: 28 (ambient), 5, 10 and 15 °C. The aim of the experiment was to determine whether the pomerac exhibited climacteric or non-climacteric respiratory patterns so that appropriate storage conditions for extending its shelf-life could be determined. On a daily basis, carbon dioxide and ethylene evolutions were measured for fruits held at each temperature. Preliminary results showed that the levels of carbon dioxide produced at 28 °C declined from 33 mL/kg per h to 23 mL/kg per h after 8 days in storage. There was no detection of ethylene for pomerac in storage, thus indicating a non-climacteric respiratory pattern. Results also indicated that as the storage temperature decreased, the levels of carbon dioxide produced also decreased both with storage time and temperature. At 5QC, the rate of respiration was lowered to the extent that the shelf-life of the pomerac was extended to 20 days.
