In this research, the effects of pulsing application of preservative solutions containing salicylic acid (100 and 200 mg/L) and methyl jasmonate (25 and 50 mg/L) and long period application of preservative solutions containing thymol (75 and 125 mg/L), menthol (75 and 125 mg/L) and eugenol (50 and 100 mg/L) on the maintain quality and extend vase-life of carnation cut flowers two tests were evaluated based on completely randomized design in four replication. Sucrose was added to all solutions at 4% and distilled water plus 4% sucrose used as control treatment. Meanwhile, the cut flowers were also kept at conditions of 25±2 ºC with air humidity (RH) of 50-55% and 3±1 ºC with RH of 80-85%. The results revealed that at the conditions of in 25±2 ºC the highest vase- life of 11 days and 10.66 days was obtained with methyl jasmonate 50 and 25 mg/L, respectively. These treatments also increased flower diameter, absorption of preservative solution and delayed petal wilting. The result indicated that with 3±1 ºC In Comparison with control (62 days), the highest vase- life of 70/03 days, 68/5 and 65/81 days were obtained in menthol 125,eugenol 100 and menthol 75 Mg/L, respectively. These treatments reduced petal wilting and increased total soluble solids, flower diameter and vase life compared to control and all other treatments.
