A study was conducted in 2008-09 to investigate the influence of Indole Butyric Acid (IBA) at 0, 1000, 1500 and 2000ppm concentrations on rooting potential in hardwood cuttings of four varieties of bougainvillea, i.e., Louise Wathen, Thimma, Mrs. Butt and Shubhra. The experiment was laid out in Randomized Block Design with sixteen treatments and four replications. Results indicated that both IBA concentration and variety had significant effect on sprouting, rooting, callusing and establishment of cuttings. Louise Wathen cuttings treated with 1000ppm IBA were superior in response with 85.39% sprouting, 75.46% rooting and 80.78% callusing. Establishment (100%) was also best in this treatment.
