Synthetic cytokinins

• Some synthetic chemical compounds which show cytokinin activity but have not been isolated from plants are known.
  
• Benzyl adenine (BA) is one such example.
  
• Although there are a few reports of this compound in plants but it’s uncommon in plants and is largely a synthetic cytokinin.
  
• Another synthetic cytokinin is thidiazuron that is used commercially as defoliant and a herbicide.
