Abstract

Jasmine of the family Oleaceae constitutes a group of plants, which are commercially grown for their fragrant flowers and essential oil production. Though it propagates through soft wood stem cuttings, due to difficult in root induction in cuttings, there is a need to find a solution for multiplication at commercial scale. Hence, the present experiment was conducted with soft wood stem cuttings with different number of nodes along with different concentrations of indole butyric acid (IBA) growth regulators and their combinations. The experiment was laid out in Factorial Completely Randomized Design with two factors and three replications. The results revealed that three node cuttings with IBA 1000 ppm took less number of days for root initiation (8.12 days), the combination of four node cuttings with IBA 2000 ppm resulted more number roots per cutting (12.86). The three node cuttings with IBA 2000 ppm interaction resulted maximum root fresh weight (0.84 g) and root dry weight (0.76 g) and highest rooting percent (89.12%).
