Abstrakt: Sour cherry is a non-climacteric fruit that quickly loses its quality after harvest, so effective storage and packaging are essential to minimize postharvest decay. Our study aimed to (i) evaluate fruit decay incidence during shelf-life for both freshly harvested and six-week-cold-stored sour cherry fruits, comparing normal atmospheric conditions with modified atmosphere packaging across three sour cherry cultivars ('Érdi bőtermő', 'Újfehértói fürtös', and 'Petri'); and (ii) assess postharvest fruit decay incidence across the following three production systems: conventional, integrated pest management (IPM), and reduced IPM, for the cultivar 'Érdi bőtermő'. The results showed that modified atmosphere packaging effectively preserved or slightly increased fruit firmness (ranging from 27.1 to 46%) compared to control fruits across all cultivars. Fruit weight loss (ranging from 1.18 to 26.1%) was also significantly reduced under modified atmosphere packaging compared to normal atmospheric storage. Over a 14-day period, the decay incidence of harvested fruits consistently increased, with major losses from day 6 onward (ranging from 17.7 to 77.0% at shelf-life day 14) across all cultivars and years. After six weeks of normal atmospheric cold storage, decay incidence remained low (ranging from 0 to 9.4%) and was comparable across all cultivars. Both normal atmospheric and modified atmosphere packaging storage maintained sour cherry quality during cold storage, but the shelf-life of the fruits was significantly shorter at room temperature, regardless of the storage methods. Fruit decay incidence at harvest was highest in the reduced IPM system (ranging from 3.2 to 6.4%), significantly exceeding those observed in the conventional and IPM systems. In post-MAP cold storage, decay incidence followed the following order: conventional < IPM < reduced IPM, with significant differences observed only between the conventional and reduced IPM systems. In conclusion, our results suggest that sour cherries produced under conventional or IPM systems and stored in modified atmosphere packaging offer an effective postharvest strategy for preserving fruit quality.
