Vase life of cut flower plays important economic values in flower production industries. In this study two levels of ascorbic acid (10 and 20 mg l -1 ) and two levels of salicylic acid (100 and 200 mg l -1 ) along with sucrose (3%) were carried out in a complete randomized design on 60 rose cut flowers cv. black magic in horticulture laboratory of agriculture faculty of Islamic Azad University, Garmsar, Iran.The recorded traits included: vase life, total chlorophyll content, anthocyanin and phenylalanine ammonialyase (PAL) content, ion leakage, superoxide dismutase content and water absorption. The results showed that salicylic acid treatments increased cutflower water absorption, fresh weight and vase life, while delay of senescence. Maximum flower vase life was recorded in treatment 200 mg l -1 salicylic acid.
