Colchicine

Vedclass · Answer

(D) Colchicine is an alkaloid extracted from the plant $Colchicum$ $	ext{autumnale}$.It acts as a mitotic poison by inhibiting the formation of spindle fibers during cell division.By preventing the separation of chromosomes during anaphase, it leads to the doubling of the chromosome number in the cell, a condition known as polyploidy.Therefore, it is widely used in plant breeding to induce polyploidy.

Which one of the following chemicals induces polyploidy in plant cells?
