Plant Growth and Development



  • Vernalization is a process of shortening of the juvenile or vegetative phase and hastening flowering by a previous cold treatment.
  • The process also prevents precocious reproductive development late in the growing season and enables the plant to have sufficient time to reach maturity.
  • The stimulus of vernalization is perceived by the meristematic cells.
  • Low temperature i.e 0-10ºc, aerobic respiration, water, proper nourishment, time period for low temperature are the requirements of vernalization.
  • Vernalin is the stimulus recived by cells that travels to all cell parts of the plant and prepares to flower.
