An experiment entitled “Effect of growth regulators on sprouting and rooting of Bougainvillea hardwood cuttings” were carried out during the year 2020 - 21 at ornamental plants nursery, Department of Floriculture and Landscape Architecture, Dr. PDKV, Akola. The experiment was laid out in completely randomized design with thirteen treatments which were replicated three times.
The results of the present investigation indicates that, among the different concentrations of IBA and NAA the hardwood cuttings treated with IBA 2000 ppm resulted better in comparison with control, with respect to different root, shoot and growth parameters
i.e. days to sprouting (9.63), number of leaves (84.5), number of shoots (3.92 ), fresh and dry weight of shoot (11.07 and 0.94 g respectively), plant height (84.66 cm), days to rooting (15.6), number of roots per cutting (26.5), length of main root (18.75 cm), survival percentage of rooted cuttings (95.33%), root volume (1.95 ml), fresh and dry weight of roots per cuttings (1.54 and 0.40 g respectively), stem girth (1.13 cm), plant spread (81.57 cm), mortality percentage (23%), Benefit: Cost Ratio of NAA (1:2:97).
