Effect of growth regulators on vegetative propagation of Amoora wallichii, Callicarpa arborea and Ficus fistulosa

A field experiment was conducted to study the effects of growth regulators, viz. IAA, IBA and NAA at different concentrations (50, 100, 200 and 300 ppm) and two dipping periods of 12 and 24 hours on the forest tree species, viz. Amoora wallichii King, Callicarpa arborea Roxb and Ficus fistulosa (Reinwdt) King. As compared to control, rooting, roots per cutting and survival percentage were increased significantly under all concentrations of IAA, IBA and NAA. Growth regulators have marked inflnence on the parameters like sapling height, diameter and number ofleaves and leaf area. With the application of higher dose of growth regulators, better results were recorded. Dipping of cutting in the solution of growth regulators for 24 hours showed better results than for 12 hours dipping. Sapling generated from stem cuttings ofthe tree species invariably get ready for transplantation after 120 days of planting. This study suggests that growth regulators can successfully be used for asexual reproduction of three species for large scale multiplication.
