Effect of Colchicine on in Vitro Polyploidy Induction in African Marigold (tagetes Erecta)
Colchicine was used as chemical mutagen for In vitro induction of polyploids. Nodal segments of In vitro grown marigold plantlets were cultured on MS medium supplemented with four different concentrations of colchcine (0.0%, 0.001%, 0.01% and 0.05%) for 12h, separately.
