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 cut-flower 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.
