Abstract: In this study, the effects of IBA doses (0, 500 and 1500 ppm) and root thickness of the R. damascena Mill cuttings on rooting rates, root counts, root lengths and shoot numbers were investigated. The results showed that IBA doses significantly affected rooting rates (p<0.05). The highest rooting rate (77.67%) was obtained from thick root cuttings with 500 ppm IBA dose application. The highest root number per cutting was found as 6.00 in thick cuttings and cuttings having no IBA application. The longest root branch per cutting was determined to be in the thick root cuttings and control cuttings (7.93 cm). The average number of root branch per cutting was determined as 0.77 in thin root cuttings and control cuttings. To conclude, R. damascena can easily be propagated with root cuttings with appropriate IBA doses, suggesting that the thicker root cuttings should be chosen for R. damascena propagation.
