Tropaeolum majus L. as edible flowers: Growth and postharvest handling

Abstract: 

To evaluate the commercial potential of Tropaeolum majus climbing mix cultivar flowers as edible produce, yield, postharvest performance in various packages and antioxidant levels were determined. Increasing the day length by artificial illumination, from 10-11 hr natural day to 16 hr and 20 hr, hastened flower development and increased flower yield during a productive period of 30 days by two and four fold, respectively. Tropaeolum majus flowers are ethylene-sensitive since ethylene application enhanced their deterioration and 1-MCP reduced it. Flowers packaged under polyvinyl chloride or polypropylene films with either passive (equilibrium) or active-modified atmosphere (MA), or without atmosphere modification (in perforated packages) demonstrated improved postharvest quality as compared with non-wrapped flowers. Nevertheless, the level of deterioration in all packages was similar and flowers were kept at marketable quality up to seven days at 2-5°C. An active modified atmosphere slightly reduced the deterioration of flowers. Results suggest that flower deterioration under PVC is probably a result of water loss and under polypropylene films is probably due to ethylene action. Antioxidant activity in yellow and orange flowers of the climbing mix cultivar was similar and lower than that in red flowers. Storage of flowers for seven days at 2-5°C did not change the antioxidant activity.
