The post-harvest behavior of nasturtium flowers was evaluated using sucrose, ascorbic acid and calcium chloride which were associated or not with polyethylene pack and stored under refrigeration. This work was carried out in a biochemical laboratory, in Dourados, Mato Grosso do Sul State, Brazil. Red and yellow flowers were immersed during thirty minutes in water, ascorbic acid at 2% and 4%, calcium chloride at 2% and 5% and sucrose at 5% and 10%, and then stored with and without package in a refrigerated chamber at 5°C ±2°C. The trial was carried out in a complete randomized experimental design in a 2 x 2 x 7 factorial scheme with three replications (8 flowers/tray). Nasturtium flowers stored with package in refrigerated chamber last for eight days, while flowers kept at environmental conditions withered after the second day. Treatments with ascorbic acid, calcium chloride and sucrose did not benefit post-harvest conservation of nasturtium flowers.
