EXTRA INFORMATION :-

★ Vegetative Propagation :

• The reproduction by which daughter plants are produced simple from the vegetative parts of a plant is called vegetative reproduction.

❒ Artificial method of vegetative reproduction :

★ Cutting :

• It is the commonest artificial method of vegetative reproduction practised by man.

★ Grafting :

• It is the process of articles method vegetative reproduction where the cutting of desired variety of plant is transplanted on another rooted plant.

★ Micropropagation :

• The production of large number of individual plantlets from a small piece of parental plant tissue, cultured in proper nutrient medium is called micropropagation.
