dc.descriptionThe aim of the present work was to evaluate the changes in polyamine (PA) content, peroxidase (POX) activity and levels of total protein and total soluble carbohydrates throughout the lifetime of leaves and inflorescences of chrysantemum 'Faroe' treated with gibberellic acidd (GA3) (used in production practices) and kept at room temperature and cold storage. The treatments were composed of four doses of GA3 (0, 15, 30 and 45 mg L-1) applied at the beggining of flower bud formation (28 days after transplanting of seedlings). After harvesting, the stems (95% of the expanded ligule) were stored at 10ºC and 95% relative humidity for 48 hrs, or kept at room temperature. For biochemical analysis samples of leaves and inflorescences were collected at the 4th, 8th, 12th and 16th day after harvest. The application of GA3 in the field and cold storage increased the content of PAs. There was an increase in POX activity in leaves and inflorescences during postharvest and this increase was related to oxidation of the PAs studied. The amount of proteins and carbohydrates in chrysantemum 'Faroe' decreased during the storage at 25ºC and under cold conditions.
