A study was conducted to investigate the influence of IBA at 0, 1000, 1500 and 2000 ppm concentration on rooting potential of hardwood cuttings of four varieties of Bougainvillea i.e. Louise Wathen, Thimma, Mrs. Butt and Shubhra in 2008. The experiment was laid out in Randomized Block Design with sixteen treatments and four replications. The result obtained indicated that both IBA concentration and variety had significant effect on sprouting, rooting, callusing and establishment of cuttings Louise Wathen cuttings treated with 1000 ppm IBA were found superior with 85.39% sprouting 75.46% rooting, 80.78% callusing,no of primary roots (19.73), secondary roots (28.8) and tertiary roots (49.19) per cutting, length of longest root (39.9 cm) and diameter of thickest root (6.61 mm). Establishment (100%) was also found best in this treatment.
