Devernalization

• The positive effect of the low temperature treatment on the vernaliztaion of the plants can be counteracted by subsequent high temperature treatment. This is called as devernalization.
  
• The degree of devernalization decreases if the duration of the cold treatment has been longer.
  
• However, the devernalized plant can again be vernalized by subsequent low temperature treatment.
