Polyploidy can be induced by the application of
Open in App
Solution
The correct option is B Colchicine
A. Auxin is plant hormone that promotes cell elongation, apical dominance, root initiation, prevents abscission and induces parthenocarpy.B. Kinetin is a cytokinin, a plat hormone that promotes cell division, delays senescence, promotes lateral bud development in dicots and promotes chloroplast development.C. Colchicine is a chemical that arrests the spindle fibre formation during cell division. As a result, chromosomes do not separate and ploidy level of the cell increases.D. Ethylene is a gaseous plant hormone which causes fruit ripening.Hence, polyploidy can be induced by the application of 'Colchicine'.
