To evaluate the effect of indolebutyric acid (IBA) and naphthaleneacetic (NAA) acid on the rooting of Indian privet (Clerodendron inerme) cuttings, an experiment was conducted using a completely randomized design with 20 replications. Concentrations of each auxin were zero (control), 125, 250, 500 and 1000 mg/l. Results showed that the highest rooting percentage (80%), root length (11.94 cm), root dry weight (0.12) and leaf number (21.6) were obtained with the 500mg/l NAA. Maximum shoot length (9.8 cm), fresh (4.48 g) and dry (0.54 g) weight were observed in 250 mg/l NAA. Highest root fresh weight was obtained in 1000 mg/l NAA treatment. The lowest rooting percentage, root and shoot lengths and shoot dry weight was belonged to control. Lowest shoot fresh weight and root fresh and dry weights were obtained with 125 mg/l IBA that was not significantly different with control. It was concluded that concentrations of 500 to 1000 mg/l NAA is optimal for rooting of Indian privet stem cutting.
