Abstract:
The research experiment was executed to assess the impact of Auxin (IBA) in different concentrations and rooting/growing media on the growth and rooting performance of Bud 9 apple rootstock. The experiment was laid out in a randomized complete block design (factorial) with twelve treatment combinations replicated thrice. It comprised of three IBA levels (0, 2000 and 2500 ppm) and four growing media (soil, sawdust, crop residue and FYM). Different levels of IBA, growing media and their interaction significantly affected shoot and root parameters of Bud 9 rootstock i.e. length of daughter shoots, the diameter of shoots, number of leaves per shoot, leaf area, leaf chlorophyll content, fresh weight of shoots, dry weight of shoots, percent of rooted shoots, the average number of roots, longest root, shortest root, average root length, root diameter, fresh weight of roots and dry weight of roots. The investigation concluded that treatment combination IBA @ 2500 ppm with sawdust as growing media was found to be superior over all other treatment combinations.
