A study on the vegetative propagation of Chinese chaste tree (Vitex negundo L.) was carried out at the Department of Horticulture, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru during August, 2010 to December, 2010. In the present experiment, the effect of growth regulators viz., IBA and NAA singly and in combinations on rooting of hardwood cuttings was studied. The treatments comprised of control, IBA at 2000 and 3000 ppm, NAA at 2000 and 3000 ppm, IBA+NAA 2000 ppm each and IBA+NAA 3000 ppm each and keradix. The experiment was conducted in a four replicated Factorial Completely Randomized Design. Single, double and triple node hardwood cuttings were treated with the growth regulator solutions. Observations were recorded on various shoot and root parameters and the survival percentage of rooted cuttings was also studied. The results of this investigation clearly brought out that, triple node hardwood cuttings should be treated with 3000 ppm IBA to obtain maximum rooting success and also for obtaining maximum survival of rooted cuttings in secondary nursery.
