*        Artificial Methods of Vegetative Propagation

 

We have developed many methods of vegetative propagation by which a new plant can be grown from a part of plant. There are three common methods of artificial vegetative propagation:

Cutting

Layering

Grafting

 

*           Cutting

In this method, a part of plant is cut and the cut portion is buried under the soil, which develops into a new plant.

 

 

*           Layering

In this method, a branch of plant is pulled down and covered with soil in such a way that the tips of the branch remain exposed in air. After few days covered part develops roots and grows into new plants.

 

 

 

*           Grafting

Grafting is a method in which two stems of two different plants are joined together to grow as a single plant. In this method one stem is taken with root, called stock and other stem is taken without root, called scion.

               

Look at the following table  

Artificial method of vegetative propagation Name of the plants,
Cutting Grapes, sugarcane, bananas, cactus, etc.
Layering Rose, pear, strawberry, jasmine etc.
Grafting Guava, mango lemon, Jasmine etc.
