In this research, the effects of different IBA (indole butyric acid) doses on the rooting of ‘Nero’ and ‘Viking’ aronia cultivars were investigated. Wood cuttings of these cultivars were used in the study. After the cuttings were disinfected, they were immersed in 1500, 2000 and 2500 ppm IBA solutions and planted in perlite medium with three replications. The cuttings were kept in a rooting system heated from below for sixty days; callus rate (%), rooting rate (%), number of roots (number), root thickness (mm), root length (cm) were evaluated. In the study, the best callus formation rate in ‘Viking’ cultivar was 55.81% at 2000 ppm, the rooting rate was in the ‘Viking’ cultivar at 2500 ppm (73.11%), the best average root number was in the ‘Viking’ cultivar at 2500 ppm IBA application (1.93 units/stem), the best average root thickness was found in the ‘Viking’ at 2500 ppm (0.23 mm) and the best average root length was found in the ‘Viking’ at 2500 ppm (0.77 cm).
