discuss,give examples,the different ways of vegetative propagation?

Answer:
Vegetative Propagation by Roots
In this process, new plants grow out of the modified roots called tubers. In fact, in some plant species, roots develop adventitious buds. These buds grow and form new plants/sprouts under the right conditions. For example, Sweet potato and Dahlia. These sprouts can be separated from the parent plant and when planted in other areas, new plants are formed.
Vegetative Propagation by Stems
Vegetative propagation occurs through stems when new plants arise from the nodes. This is where buds are formed, which grow into new plants. Stems that grow horizontally on the ground are called runners. As these runners grow, buds form at the nodes, which later develop the roots and shoots, resulting in the formation of a new plant. Example – Cyanodon; Mint etc.
The bulb is the round, swollen part of the underground stem. Within the bulb lies the organ for vegetative propagation such as the central shoot that grows into a new plant. Bulbs have a bud surrounded by layers of fleshy leaves. A few examples include Onions, Garlic, and Tulips etc.
We can find stem tubers in plants like potatoes. This part is the swollen apical part containing many nodes or eyes. Every eye has buds. New plants originate from these buds.
Vegetative Propagation by Leaf
Plants like Bryophyllum, Begonia etc., have adventitious buds coming out from the notches of the leaves. These buds develop into new plants.

Cutting
Cuttings are the most common method employed by gardeners to grow new plants. A portion of the stem is cut and planted in the soil, which develops roots and further grows into a new plant.

Grafting
In grafting, we use two closely related plants to produce a new plant that has the desired, combined traits of both the parent plants. One plant is the stock, of which we take the root system and the other is the Scion, of which we use the shoot system. In this method of artificial vegetative propagation, we attach the scion to the stock of the second plant. In general, we use grafting for a variety of plants such as roses, apples, avocado etc.
Budding
In this method, we take a bud with a small portion of the bark from the desired plant. Then we insert it into a small slit made in the bark of the other plant. Next, we tie both the plants together and do not allow the buds to dry.
