Abstract: The postharvest quality and vase life of cut flowers, including tuberose ( Polianthes tuberosa ), face challenges such as incomplete floret opening and premature abscission, reducing market value. This study investigates the use of ozonized water, produced via Cold Plasma Technology (CPT), as a sustainable postharvest treatment. Tuberose flowers were treated with ozonized water for 4, 6, 8, and 10 minutes, and key parameters such as floret abscission, antioxidant enzyme activities, phenolic compounds, and lipid peroxidation were analyzed. Results showed the 8-minute treatment significantly improved vase life by enhancing antioxidant activities, increasing phenolic compound levels, and reducing lipid peroxidation, thereby delaying senescence and preserving cellular integrity. This eco-friendly method offers an effective alternative to chemical treatments, addressing industry demands for sustainable practices by extending vase life, preserving aesthetic quality, and reducing environmental impact. These findings support broader adoption of CPT-based ozonized water in postharvest management.
