Aim of this study is to investigate the interrelation between ethylene production, DA index (I AD), and postharvest treatments in four apricot (Prunus armeniaca L.) cultivars: 'Buda', 'NS Kasnocvetna', 'NS Rodna', and 'NS6'. Apricots were harvested with I AD values between 0.41-0.80, stored at 1 °C for 15 days, followed by 3 days of shelf life at room temperature. Ethylene production and I AD were measured at harvest, after cold storage, and after shelf life. Preharvest treatments included nitrogen (N) and calcium (Ca), while postharvest treatments included modified atmosphere packaging (MAP) and 1-methylcyclopropene (MCP). Results showed cultivar-specific ethylene responses and I AD, with 'Buda' exhibited the most rapid decline of I AD and highest ethylene levels, and 'NS6' showing a lower decrease of I AD, especially under MAP and Ca treatments. Postharvest treatments effectively reduced a decrease of I AD for all tested cultivars. The findings highlight the need for cultivar-specific calibration of the I AD index to optimize the management of apricots at a given ripeness stage, thereby maintaining their overall quality and storage capability.
