Three-year experiment was carried out on the effect of maturity stage and method of packing on the quality of stored aubergines ‘Murena F1’. The fruits were obtained from plants cultivated in a glasshouse and a plastic tunnel. Harvesting was carried out in three maturity stages and the fruits were packed, using four different methods. The aubergines were stored for four weeks at 12°C, and then visual quality, firmness, and weight losses were evaluated. Gas composition in the packages was also measured. Aubergines harvested at the latest stage had the best visual quality after storage. The smallest changes in visual quality as well as the smallest weight losses (below 1%) were observed in the case of fruits individually wrapped in PE film. Oxygen level inside the packages decreased to 18% and carbon dioxide increased to 2-4%.
