Influence of growth hormones and nodal cuttings on rooting of Vitex negundo (l.)

A study on the vegetative propagation of Vitex negundo (L.) was conducted in University of Agricultural Sciences, Bengaluru during 2010–11 with a four replicated factorial CRD. Single, double and triple node hardwood cuttings were treated with different growth hormone solutions and observations were recorded. The shoot parameters such as days taken to sprout (9 days), number of sprouts(3.23), length of the longest sprout (20.38 cm), fresh weight (3.6 g) and dry weight (0.88 g) of sprouts and the root parameters like time taken to root (30 days), number of roots (19.05), length of the longest root (21.75 cm), fresh weight (2.37 g) and dry weight (0.67 g) of roots were significantly higher in triple node stem cuttings treated with Indole Butyric Acid 3000 ppm. Thus triple node hardwood cuttings treated with 3000 ppm Indole Butyric Acid (IBA) obtained maximum rooting success.
