An experiment was laid out under mist chamber at Horticultural Research Center, Chauras Campus, HNB Garhwal University, Srinagar (Garhwal), Uttarakhand, India, during the month of February, 2011. Three different lengths of terminal stem cuttings (20, 35 and 50 cm) of Bougainvillea glabra cv. Torch Glory were planted in the root trainers after treatments of IBA solutions of 3000, 4000 and 5000 ppm concentrations by quick dip method. Rooting media was prepared by mixing equal amount of sandy soil and FYM. Among all the treatments, maximum number of sprouted cuttings (90.0%), number of sprouts per cuttings (30.22), number of primary roots (33.00), fresh and dry weight of roots were observed under C1L2 (35 cm long cuttings treated with 3000 ppm, concentration of IBA) treatments. The maximum length of sprout per cuttings (3.25 cm), height of plant (63.86 cm), and profuse secondary rooting were found under C1L3 (50 cm long cuttings treated with 3000 ppm concentration of IBA) while diameter of sprouts per cuttings (0.48 cm) was recorded under C3L2 (35 cm long cuttings treated with 5000 ppm concentration of IBA). The maximum number of leaves on new growth (7.48) was observed under C3L3 (50 cm long cuttings treated with 5000 ppm concentration of IBA) treatment. The length of longest root (9.90 cm) was recorded under C2L3 (50 cm long cutting treated with 4000 ppm IBA) treatment, while diameter of longest root (0.13) was recorded under C1L1 (20 cm long cuttings treated with 3000 ppm concentration of IBA). All the cuttings treated with IBA produce callus formation while all the rooted cuttings under the C1L3, C2L1, C2L2 and C2L3 (50, 20, 35 and 50 cm long cuttings treated with 3000, 4000, 4000 and 4000 ppm concentration of IBA, respectively) treatments produce secondary rooting.
