【 摘 要 】

This experiment was conducted on rose cut flowers, Red Naomy cultivar, with the length of 35 cm, for 18 hours as a short-term treatment in a factorial based on completely randomized design with five treatments including sucrose + 8-Hydroxyquinoline sulfate, salicylic acid + sucrose + 8-Hydroxyquinoline sulfate, ascorbic acid + sucrose + 8-Hydroxyquinoline sulfate, Salicylic acid + ascorbic acid + sucrose‌ + 8-Hydroxyquinoline sulfate and distilled water as control, and three replications in bottles. Morphological traits such as shelf life, changes in water uptake, fresh weight, flower diameter and physiological traits such as total protein and proline contents were measured. The results showed that combination of Salicylic acid + sucrose + 8-Hydroxyquinoline sulfate treatment significantly affected shelf life compared to control and other treatments. The results also revealed that the combination of Salicylic acid + ascorbic acid + sucrose‌ + 8-Hydroxyquinoline sulfate delayed flowers senescence and increased the amount of water uptake, fresh weight and flower diameter. Moreover, the greatest protein and proline contents were obtained under ascorbic acid + sucrose + 8-Hydroxyquinoline sulfate treatment and sucrose + 8-Hydroxyquinoline sulfate, respectively.
