Effect of growth regulators on vegetative propagation of Vitex negundo L

Abstract

An experiment was conducted in Department of Horticulture, GKVK, Bengaluru during the year 2010 to study the effect of growth regulators on vegetative propagation of Vitex negundo. Among the growth regulators treatment 3000 ppm IBA recorded early sprouting (12.42 days), maximum sprouting (89.44 %), more number of sprouts (2.12) per rooted cutting, longest sprout (16.71 cm), fresh (2.64 g) and dry weights (0.63 g) of sprouts per rooted cutting, early root initiation (33.42 days), highest rooting percentage (82.22 %), more number of roots per cutting (15.59), length of longest root (15.31 cm), fresh (1.02 g) and dry weights (0.30 g) of roots per cutting and cent per cent survival in secondary nursery. Hence, IBA at 3000 ppm was found to be best for vegetative propagation of Vitex negundo.
