Effect of Growth Regulators in Rooting Performance of Stem Cuttings of some Shrub Species of Western Himalaya

All the three shrub species under study recorded better results with regard to sprouting, call using and ischolar_maining under prolonged dip treatment in IBA and NAA for 24 hours as compared to a quick dip. The best ischolar_maining treatment in cuttings of species investigated is as follows- Woodfordia prolonged dip in 100 ppm NAA, Debregeasia prolonged dip in 50 ppm IBA and Coriaria prolonged dip in 100 ppm IBA. The number of ischolar_mains in Woodfordia and Coriaria was maximum with a prolonged dip in NAA and in Debregeasia a quick dip in IBA provided maximum number of ischolar_mains. Average ischolar_main length was maximum with quick dips in NAA for all the three shrub species under study.
