Polyploidy can be induced by the application of

  • Auxin

  • Kinetin

  • Colchicine

  • Ethylene

Solution

C.

Colchicine

Colchicine is a poisonous chemical, isolated from seeds and bulbs of autumn crocus (Colchicum autumnale). It blocks spindle formation and thus, inhibits the movement of sister chromatids to the opposite poles. The resulting restitution nucleus includes all the chromatids. As a result, the chromosome number of the cell is doubled, which leads to polyploidy.
