MPlums, as climacteric fruits, undergo significant physiological changes during postharvest storage, primarily influenced by ethylene production and respiration. This study investigated the effects of storage temperature and duration on the physiological and structural changes of the two most popular cultivars in the Hungarian market. The ‘Stanley’ and ‘Elena’ plums were stored at temperatures of 1, 5, 10, and 15°C for 24 days. The ethylene production, respiration and microscopic structure measurements were performed at 4-day intervals. However, some sample groups were terminated early due to overripeness and softening, making it difficult to measure. The results revealed that ethylene production and respiration rate increased with storage temperature, accelerating the ripening process. Additionally, microscopic images showed an increase in epicuticular wax, damaged cells and open stomata after storage, which may be related to the ripening and softening of the plums. Thus, the microscopic technique, combined with ethylene and respiration measurements, is promising for monitoring the structural and physiological changes affecting plum quality during postharvest storage.
