This study was carried out to determine the effects of different indolebutyric acid (IBA) doses (1000, 3000, 5000, and 0 (control) ppm) on rooting of semi-wood Phlomis chimerae cuttings. Cuttings were exposed to different IBA solutions in the greenhouse and planted in perlite growing medium. The experiment was planned according to completely randomized design with 3 replications and 10 cuttings per each repetition. In the study rooting ratio (%), root number (number of roots/cutting), root length (cm.), dry root and dry cutting weights (gr.) were measured after 14 weeks from the begining of study. The results revealed that the effect of different doses of IBA applications on rooting in Phlomis chimerae cuttings was found to be significant in terms of some measured properties. When the rooting rate between different IBA doses applied to cuttings was examined, although there was a mathematical increase between IBA doses and rooting rates, but all doses were in the same homogeneous group according to the Duncan test results, so there was no statistically significant difference in rooting rate. It was determined that the highest values were at 5000 ppm IBA dose according to root number, root length, root and cutting dry weights. It was concluded that the increasing dose of IBA could be useful. As the IBA dose applied to cuttings increases, an increase was observed in root number, root lenght, root and cutting dry weight.
