dc.description.abstractABSTRACT The present investigation entitled “Effect of IBA concentrations and growing media on growth and rooting performance of apple rootstock Bud 9” was undertaken at Pandah Experimental Farm of Department of Seed Science & Technology, Dr Y S Parmar University of Horticulture and Forestry Nauni, Solan H.P. during 2021-2022. The experiment was laid out in Randomised Complete Block Design (Factorial) with twelve treatment combinations replicated thrice, comprising of three IBA levels (0, 2000 and 2500 ppm) and four growing media (soil, sawdust, crop residue and FYM). Among different levels of IBA, the treatment IBA @ 2500 ppm recorded length of daughter shoot (137.26 cm), diameter of daughter shoot (10.41 mm), number of leaves (76.40), leaf area (44.99 cm2), leaf chlorophyll content (2.01 mg g-1), fresh weight of daughter shoot (118.65 g), dry weight of daughter shoot (61.66 g), per cent rooted shoots (73.98 %), average number of roots (10.85), longest root (27.95 cm), shortest root (6.85 cm), average root length (26.38 cm), root diameter (1.66 mm), fresh weight of roots (69.04 g), dry weight of roots (38.95 g), root: shoot ratio (0.61) and total biomass of rooted shoot (100.61 g). Among growing media, sawdust resulted in maximum length of daughter shoot (118.12 cm), diameter of daughter shoot (10.39 mm), number of leaves (74.10), leaf area (39.59 cm2), fresh weight of daughter shoot (117.16 g), dry weight of daughter shoots (62.41 g), per cent rooted shoots (67.73 %), average number of roots (10.14), longest root (27.51 cm), shortest root (6.55 cm), average root length (27.31 cm), root diameter (1.86 mm), fresh weight (66.41 g) and dry weight of roots (35.94 g), total biomass of rooted shoot (98.35 g). The interaction of IBA @ 2500 ppm + sawdust had exhibited maximum length of daughter shoot (143.73 cm), diameter of daughter shoot (12.12 mm), number of leaves (79.16), leaf area (48.18 cm2), fresh (143.50 g) and dry weight of shoots (74.50 g), per cent rooted shoots (76.23 %), average number of roots (13.16), longest root (32.11 cm), shortest root (9.11), average root length (32.16 cm), root diameter (2.34 mm), fresh weight of roots (86.16 g), dry weight of roots (50.50 g) and total biomass of rooted shoot (125.00 gen_US
