Abstract:
The objective of this study was to assess the effectiveness of colchicine and oryzalin in inducing polyploidy in Bougainvillea peruviana cv. Shubhra. Colchicine was administered at concentrations ranging from 0.1% to 0.5%, and oryzalin was applied at concentrations ranging from 50 to 200 µM, with treatment durations spanning from 48 to 96 hours. To assess the polyploidisation flow cytometry was employed to screen the ploidy levels of the treated plants. Colchicine was more efficient than oryzalin in terms of polyploidy induction, leading to notable variations in the vegetative characteristics of Bougainvillea.
