The process of growing many plants from one plant by man-made methods is called artificial propagation of plants. A number of methods of artificial propagation of plants are used in agriculture (for raising crops), and horticulture (cultivation of vegetables, fruits and flowers). The three common methods for the artificial propagation of plants are:
Cuttings,
Layering, and
Grafting.
● LAYERING
In this method, a branch of the plant is pulled towards the ground and a part of it is covered with moist soil leaving the tip of the branch exposed above the ground. After some time, new roots develop from the part of the branch buried in the soil. The branch is then cut off from the parent plant. The part of the branch which has developed roots grows to become a new plant (just like the parent plant). Jasmine plant (chameli) is propagated or produced by the layering method.
● GRAFTING
Grafting is a method in which the cut stems of two different plants are joined together in such a way that the two stems join and grow as a single plant. This new plant will have the characteristics of both the original plants.
The cutted stem of a plant having roots and fixed in the soil is called stock. Stock is the lower part of a plant having the roots.The cutted stem of another plant without is called 'scion'. Scion is the upper part of a plant which may have leaves on it .
In carrying out grafting, two plants are chosen which are to be used as scion and stock. First, the stem (or branch) is removed from the plant chosen to be made scion (for its desirable characteristics) by making a slanting cut. This gives us the scion with a slanting cut. The stem of second plant (or tree) to be used in grafting is also cut in a slanting way. The lower part of this plant (or tree) is stock. It has also a slanting cut.
The scion is placed over the stock. The cut surfaces of the scion and stock are fitted together and bound tightly with a piece of cloth and covered properly with polythene sheet (so as to prevent harmful infection by bacteria or fungus, and loss of water and plant sap from the cut and joined ends of stock and scion).
While joining the scion to the stock, care should be taken to make sure that the cambium layer of scion is in contact with the cambium layer of stock (because the cambium layer in the stem is responsible for growth).
The cut soon heals and the stock and scion of two plants grow together and become one plant. The scion continues to produce its original leaves, flowers and fruits but it gets water and minerals for making food from the chosen stock. So, the fruits will have the characteristics of both the plants (from which scion and stock have come).
Grafting is used to breed fruit trees and flowering bushes. Apple, peach, apricot and pear trees are often grafted. We will now describe some of the advantages of the grafting method of artificial propagation
●CUTTING
A small part of plant which is removed by making a cut with a knife with a sharf knife is called Cutting. A cutting may be a peice of stem , stem , root or even a leaf . While making a cutting, care should be taken to see that there should be no bud on it.

Explanation:
it is a type of asexual plant reproduction in which new plant are obtained from a part of the parents plant under favourable conditions various structure take part in this type of reproduction is known as natural vegetative propagation plant part like to develop into new plants the property of vegetative propagation is used in cutting their and drafting Pizza known as methods of artificial vegetative propagation they are used for many plants like sugarcane roses grade by farm
