What do you mean by vegetative …

The growth of new plants from vegetative parts of the plant like roots, stem, and leaves other than the seeds is called vegetative propagation. Various artificial methods of vegetative propagation are:

1. Cutting: Small piece of plant parts like roots, stem or leaves is cut and used for propagation. Examples: Rose, sugarcane etc.
2. Layering: It is the process where roots are induced when a stem comes in contact with the ground. Examples: Grapevine, mango etc.
3. Grafting: It is a process of joining a part of a living plant like a stem or bud to another plant and they grow as one plant. Examples: Lime, lemon etc.
4. Propagation by plant tissue culture: In this method, plant cells are cultured in an artificial culture media, where a cell divides into an undifferentiated mass of cells called callus which is transferred to different nutrient mediums to grow into plantlets.

In natural methods of vegetative propagation underground roots [Root tubers of Dahlia] or underground stems [bulbs of onions, rhizomes of ginger] or adventitious buds on leaves [Bryophyllum] grow into new plants.
