Abstract: Maintaining postharvest quality is critical for preserving the marketability and nutritional value of parthenocarpic cucumbers. This study aimed to evaluate the effects of UV-B and UV-C radiation on the postharvest quality, including antioxidant compounds, of parthenocarpic cucumbers during room temperature storage. Cengel cucumbers were exposed to 0.54–19.80 kJ·m−2 doses of UV-B, and 0.20–10.35 kJ·m−2 doses of UV-C. Non-irradiated cucumbers served as controls. The fruit were packed in a cotton box and stored at room temperature (27 ± 2 °C), with 75 ± 2% relative humidity, for 7 days. Results showed that low doses of UV-B and UV-C reduced weight loss and wilting, while high doses accelerated color change and increased weight loss and wilting. UV-B did not affect fruit firmness, total titratable acidity, soluble solids, or phenolic contents, while UV-C reduced these parameters. UV-B treatment resulted in higher ascorbic acid and FRAP antioxidant activity in the first three days compared to controls. A low dose of UV-B may enhance ascorbic acid content and antioxidant activity in parthenocarpic cucumbers during short-term storage. This approach has potential applications in food preservation by reducing postharvest losses and maintaining nutritional quality. Future research should explore the combined effects of UV-B treatment and low-temperature storage for further benefits.
