An experiment on stimulation of rooting of Bougainvillea peruviana cv. Thimma using two different rooting hormones (IBA and NAA) was conducted at Bougainvillea Repository, Division of Floriculture and Landscaping, IARI, New Delhi between the months of February to April, 2017. The experiment was laid out in Completely Randomized Design (CRD) with three replicates. Data were collected on days to first sprout, no. of vegetative buds/plant, rooting per cent age, length of longest shoot, shoot fresh wt./plant, shoot dry wt./plant, length of longest root/plant, fresh wt. of root/plant and dry wt. of root/plant. The results showed that the treatment of cuttings with IBA (6000 ppm) was significantly better than the control and all the other treatments with respect to rooting of cuttings like days to first sprout (11.66 days), no. of vegetative buds/plant (4.333), rooting per cent age (90.00%), length of longest shoot (38.0 cm), shoot fresh wt./plant (22.333 g), shoot dry wt./plant (3.843 g), length of longest root/plant (18.233 cm), fresh wt. of root/plant (7.527 g) and dry wt. of root/plant (1.58 g) followed by IBA (5000) ppm and IBA (2500 ppm) + NAA (2500 ppm) compared to control and other treatments, irrespective of the use of plant growth regulators.
