Abstract: The present investigation was taken up during rainy season of 2012-13 at Horticultural Nursery, College of Agriculture, Gwalior. The treatment consisted of 7 levels of PGRs (control, IBA-5000 ppm, IBA-7500 ppm, NAA-5000 ppm, NAA-7500 ppm, IBA+NAA-5000 ppm each and IBA+NAA-7500 ppm each) and two rooting media (Moss grass and Moss grass + coco-peat). Significantly maximum percentage of callus formation (0.948 cm/air layer), number of primary roots (15.50/air layer), length of primary roots (4.56 cm), diameter of primary roots (2.995 mm), number of secondary roots (31.39/air-layer), length of secondary roots (2.551 cm), diameter of secondary roots (0.673 mm), dry weight of roots (0.692 g), rooting success (80.17%), Maximum callusing (0.693 cm/air layer), number of primary roots (10.16/air layer), length of primary roots (3.55 cm), diameter of primary roots (2.430 mm), number of secondary roots (22.90/air-layer), length of secondary roots (1.768 cm), diameter of secondary roots (0.530 mm), dry weight of roots (0.564 g), rooting success (62.80%) were noted under the rooting media M2 (Moss grass+coco-peat), which significantly proved superior over rooting media M1 (moss grass) in respect of all these characters. Significantly maximum length of primary root (4.99 cm), diameter of primary root (3.286 mm), number of secondary roots (34.08/ air layer), length of secondary roots (2.858 cm), rooting success (82.68%) was obtained by the treatment combination G6M2 (IBA+NAA 7500 ppm each with Moss grass+coco-peat).
