The experiment was carried out to investigate the effect of different concentration of Indole-3-butyric acid (IBA) on the rooting ability of semi-hardwood Bougainvillea flower. The treatments were control (without IBA), 2000, 3000 and 4000 ppm IBA. The cuttings were treated with IBA solution for 7 seconds and immediately transferred to the rooting medium. Perlite was used as a rooting substrate. Treatment was evaluated in a completely randomized design (CRD) with 3 replications. According to the obtained results, there was no significant difference between IBA treatment and control on rooting percentage. The best effect of different levels of IBA on the number of root (8.67 roots per plant) was obtained at 2000 ppm IBA. The highest root length (151.42 mm) was observed at control and there was no significant difference between control and 2000, 4000 ppm IBA. It can be concluded that using perlite as a rooting substrate without using IBA (control) affected rooting ability in bougainvillea flower.
