The study reports results on the effect of Indole-3-butyric acid (IBA) and α-naphthaleneacetic acid (NAA) on rooting of cuttings of Rosa damascena Mill. The experiment was arranged as factorial, based on Ranomized Complete Block (RCB) design with four replications. The treatments were with IBA (0, 1000, 2000, 3000, 4000, and 5000 mg l^-1) and NAA (0, 1000, 2000, 3000, 4000, and 5000 mg l^-1). The cuttings were harvested under fog system. The percentage of rooted cuttings and number of roots were evaluated after 70 days. The effect of different concentration of auxin on all studied traits was significant at 1% level. IBA in higher concentrations and NAA in lower concentrations increased the rooting of cuttings. In NAA, with increasing of concentration to more than 2000 mg l^-1, growth was reduced compared to the control. The highest percentage of rooting was observed after treatment with 1000 mg l^-1 NAA (84%) and 5000 mg l^-1 IBA (66%). The results of evaluation of quality traits of cuttings (number of roots, root diameter and length, fresh and dry weight of the formed roots, length of the formed shoots, fresh and dry weight of the formed shoots and leaves) showed that the best rooting and root system was related to 5000 mg l^-1 IBA treatment.
