Current work was conducted to evaluate the influences of hot water dipping (HWD) treatment and its combination with Eucalyptus leaves on the postharvest storability of Cyprus local mandarins. This experiment consisted of five different treatments, which are: 1) control (dipping fruits into tap water for 3 min); 2) hot water dipping (HWD) at 55°C for 2 min; 3) hot water dipping (HWD) at 55°C for 3 min; 4) hot water dipping (HWD) + Eucalyptus leaf (EL) at 55°C for 2 min; and 5) hot water dipping (HWD) + Eucalyptus leaf (EL) at 55°C for 3 min. Overall results suggested that the incorporating Eucalyptus leaves into the HWD treatment improves the efficacy of the HWD, and makes it possible to reduce the dipping duration required for higher positive impact on the postharvest fruit quality (including weight loss, fruit firmness, visual quality, decay incidence, juice percentage, soluble solids concentration, titratable acidity and ascorbic acid content). According to the main findings obtained, at the end of the experimental study period (60 days of storage), the minimum weight loss, the best visual appearance, minimum decay incidence and highest ascorbic acid content were all observed from the fruits treated with the combination of Eucalyptus leaves and HWD for 2 min duration.
