Abstract:

Vegetative propagation of Jamun (Syzygium cumini L. Skeels) through cutting is the most convenient and the cheapest method to obtain true to type plants in considerably lesser time. In the present study, effect of various concentration of PGR’s on the rooting ability of different types of stem cuttings of jamun was assessed at College of Horticulture, University of Horticultural sciences, Navanagar, Bagalkot (Karnataka) India. The experiment was laid out in Factorial Completely Randomized Design. There was significant differences among treatments in various shoot and root parameters recorded. The hardwood cuttings and rootex (commercial formulation) were significantly best with respect to most of the shoot and root parameters. In the interaction of treatments, number of days taken for sprout initiation was found early in T21 (Hardwood cutting and Rootex, 8.65days), the highest number of sprouts (12.05), number of leaves per cutting (9.15) and length of shoots (8.64 cm) at 30, 60 and 90 DAP, sprouting percentage (29.90), fresh weight of cuttings (21.47g), dry weight of cuttings (14.25g), number of primary and secondary roots (57.60), length of longest root (16.85cm), and rooting percentage (35.40) at 90 DAP was more in interaction T21 (Hard wood cutting and rootex). Overall, T21 having interaction of hard wood cutting and rootex was shown superior results as compared to other treatments.
