Explants obtained from the apical, middle and basal parts of R. gangetica were allowed to regenerate in petri dishes containing filter papers moistened with half-strength Knop's liquid culture supplemented with L. camara root, stem and leaf extracts at various concentrations (5, 10, 15, 20, 30, 40 and 50%). The regeneration percentage decreased with the increase in extract concentration. The leaf extract was the most inhibitory (mean regeneration value of 22.85%), followed by the stem (32.37%) and root (47.61%) extracts. The apical explants showed the greatest potential for regeneration (up to 47.61%), followed by the middle (39.99%) and basal (25.71%) explants. The regeneration was directly proportional to time and inversely proportional to the concentration of allelochemicals in the extracts.
