Plant Nutrition :: Plant Growth Regulators


  • Neljubow (1901) is credited with having identified the active growth-regulating component of the illuminating gas as ethylene.
  • Ethylene is formed naturally in plants in amounts sufficient to bring about regulatorly effects and it might be considered as plant hormone.
  • Ethylene may be active in alleviation of secondary dormancy also (Ross,1984).
  • Synthetic chemical known as Etherel, Ethephon, Chloroethyl phosphonic acid (CEPA) has been reported to release ethylene when applied on plants.

Role of ethylene

  • Breaking dormancy                                    
  • Induce ripening of fruits
  • Induce abscission of leaves            
  • Inhibit elongation and lateral bud growth
