EFFECT OF IBA AND NAA CONCENTRATIONS ON ROOTING IN STEM CUTTINGS OF NIGHT QUEEN (Cestrum nocturnum L) UNDER SUB-TROPICAL VALLEY CONDITIONS

The experiment was carried out in simple randomized block design. .The different length stem cuttings of Cestrum nocturnum were treated with IBA and NAA solutions at 100, 200and 300 mg L-1 by soaking method. Among all the treatments, number of sprouted cuttings and rooting per cent (76.53), length of the roots/cutting (23.76 cm), fresh weight (6.06 g) and dry weight (1.33 g) of roots were higher in IBA 100 mg L-1. While the maximum length of sprout/cutting (190.00 cm) was in IBA 300 mg L-1 and highest number of roots/cutting (91.00) was recorded in NAA 300 mg L-1 treatment.
