TECHNIQUE OF GRAFTING PLANTS:
-
Grafting is the technique or an art of joining two cut surfaces of the same or different plants such that they unite and grow together as one plant.
-
The principle behind this technique is bringing together the cambia of stock and scion for union.
-
Stock: Plant on which grafting is done.
-
Scion (Graft): Plant part inserted on the stock.
-
For grafting to be successful, both should be mutually compatible, i.e. matching of cambia.
-
The stock has strong root system, while the scion has weaker root system, but better variety of fruits and flowers.
-
This technique is carried out in dicot plants as they have cambium for secondary growth.
-
Since monocots lack intra and interfascicular cambium, grafting cannot be carried out.
-
The stock gives rise to root, while scion becomes the shoot of the new plant.
-
Common methods of grafting include Tongue (whip) grafting, wedge grafting, crown grafting, etc.
