Options

  1. Avernalization
  2. Bcryobiology
  3. Cphotoperiodism
  4. Dprunning

Correct answer

A. vernalization

Step-by-step solution

Vernalization is chilling or cold treatment of the young plants or seeds to induce flowering. It is a process of shortening of the juvenile or vegetative phase and fastening the flowering by a process of cold treatment.
