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. |
