1200 cuttings made from the trees of Plum cv. Kala Amritsariwere planted in 60 beds of size 1×1m., with 20 cuttings on each bed. Uniform sized 40 cuttings per replication were treated with ten treatments of IBA and PHB growth regulators by slow dip (24 hours) and quick dip (2 minutes) method before planting along with control.Results showed that IBA@2000ppm quick dip was found to be significant in improving the shoot and root characters in cuttings with maximum shoot length (16.87cm), average shoot girth (0.46cm), shoot number (4.22), fresh weight of shoots (6.82), dry weight of shoots (1.43g), leaf number (154.28), average leaf area (305.79 cm2 ), root number (44.90), average root length (10.88cm), length of longest root (13.5cm), fresh weight of roots (1.52g), dry weight of roots (1.09). While the cuttings treated with slow dip of IBA 150 ppm exhibited significant survival percentage (81.00%), percentage of rooted cuttings (74.33%) and sprouting percent (75.17%).
