Explain clearly about Cutting, Grafting and Layering techniques.

Answer»

Cutting: 

  • In this method, stem cuttings are used to obtain new plants. 
  • In order to promote rooting these are treated with IAA. 

Grafting: 

  • In this method, a branch of the plant having desired features are inserted in a rooted plant called stock. 
  • The branch which is inserted is called scion. 
  • This is practised to produce a new variety. 

Layering: 

  • In this method, roots are induced on the stem while it is still attached to the parent plant. 
  • This part is then separated from the parent plant and grown as an independent plant.
