Abstract
The present study was conducted to improve upon the micropropagation protocol of Rose cultivars by modification of the MS medium through variations in sucrose and agar concentrations thereby enhancing the shoot multiplication and rooting efficiency of the nodal explants. High sucrose concentrations and low agar concentrations favoured shoot mutiplication during the in vitro stages. Enhanced multiplcation and growth was observed on sub culturing the mother explants with regenerated shoots on fresh MS medium containing sucrose (3.5%, w/v) and agar (0.6%, w/v), supplemented with lower concentrations cytokinin combination of BAP and KN (2.5 mgl-1+1.5 mgl-1) respectively. Half strength MS medium containing sucrose (2.0%, w/v) and agar (0.3%, w/v) with NAA and BAP (2.0 mgl-1+0.5 mgl-1) in combination was most effective for rooting.
