Application of which plant hormone overcomes the requirement of vernalization?

Options

  1. ACytokinins
  2. BAuxins
  3. CGibberellins
  4. DEthylene

Correct answer

C. Gibberellins

Step-by-step solution

Vernalization is the process of inducing flowering in plants by exposing them to prolonged cold temperatures. In certain plants, especially biennials such as cabbage and carrots, the requirement for cold treatment can be replaced by the application of gibberellins. Gibberellins stimulate stem elongation (bolting) and induce flowering, thereby overcoming the need for vernalization. Answer: Gibberellins
