In this research, the effects of thidiazuron pulse treatment and salicylic acid were examined to improve vase life and maintain the quality of Alstroemeria ҅Modena҆ cut flowers. The experiment was done in a factorial experiment based on RCD with 16 treatments, 3 replications and 48 plots. The flowers were placed in different concentrations of thidiazuron (0, 10, 20, and 50 μM) and salicylic acid (0, 100, 200, and 300 mg l-1) for 24 hours. Then cut flowers were put in a preservative solution containing 3% sucrose and 300 mg l-1 8-HQS.Then, vase life and quality traits such as fresh weight, dry weight, water uptake, amount of soluble solids (˚brix) and cell membrane stability (electrolyte leakage) were evaluated during examination. The results showed that the concentration of 200 mg l-1 salicylic acid, has the highest water uptake and lowest reduction of fresh weight in comparison with the other treatments. In all treatments except for the control, dry weight and soluble solids increased.Also, 20 μM thidiazuron and 100 mg l-1 salicylic acid showed the greatest stability of the cell membrane compared to the control treatment. Finally, 20 μM thidiazuron and 200 mg l-1 salicylic acid with the highest vase life of cut alstroemeria ҅Modena҆ compared to the other treatments is recommended to extend the vase life.
