Abstract

                                Four growth regulators viz.. IAA, IBA, NAA & GA each at three concentrations of 50, 100 and 200 ppm were used for rooting of semi-hard as well as hard-wood stem cutting in D.Sissoo. A conjoint evaluation, of all parameters brought into limelight the superiority of 200 ppm IBA. A comparison of the nature of the cuttings revealed the better performance of semi-hard wood than the hard wood cuttings. Thus for vegetative multiplication of D.Sissoo use of semi-hard wood stem cuttings and their immersin in 200 ppm IBA for four hours are found to be encouraging.

Key words : Vegetative propagation, Dalbergia sissoo
