The effect of Indole-3-butyric acid (IBA), season and pre-conditioning (girdling) was evaluated on the rooting performance of Acer acuminatum cuttings. Girdling was done one month prior to collection of cuttings from the forest in two seasons (spring and monsoon). The representative cuttings were treated with different concentrations of IBA. IBA at 0.75% IBA provided significantly maximum sprouting (71.67%), rooting (41.25%), root length (8.84 cm), number of roots (7.84) and mean dry root weight (396.17 mg/cutting). The rooting of A. acuminatum cuttings was influenced by season of planting giving better results during the spring season (March-April). Rooting process was also significantly better for girdled cuttings of A. acuminatum. Therefore to achieve the highest rooting success, girdled cuttings of A. acuminatum should be collected in spring season (March-April) and treated with 0.75% IBA.
