Naveen Sharma 8 years, 9 months ago

Ans. Vernalization is a process of shortening of the juvenile or vegetative phase and hastening flowering by a previous cold treatment.

Site for Vernalization: The stimulus of vernalization is perceived only by the meristem­atic cells, e.g., shoot tip, embryo tips, root apex, developing leaves, etc..

Importance of Vernalization:

  • Vernalization can help in shortening the juvenile or vegetative period of plant and bring about early flowering. It is not only applicable to temperate plants but also to some tropical plants, e.g., Wheat, Rice, Millets, Cotton,
  • It increases yield, resistance to cold and diseases, and
  • Kernel wrinkles of Triticale can be removed by vernalization.
