The horizontal stems grow above ground along the soil surface an produce adventitious roots and new shoots
This technique involves the culturing of plant cells that may be taken from different parts of a parent plant. The tissue is placed in a sterilized container and nurtured in a special medium until a mass of cells known as a callus is formed. The callus is then cultured in a hormone-laden medium and eventually develops into plantlets. When planted, these mature into fully grown plants.

In grafting, a desired cutting or scion is attached to the stem of another plant that remains rooted in the ground. The tissue systems of the cutting become grafted into or integrated with the tissue systems of the base plant over time.
This method involves bending plant branches or stems so that they touch the ground. The portions of branches or stems in contact with the ground are then covered with soil. Adventitious roots or roots that extend from structures other than plant roots develop in the parts covered by soil and the attached shoot branch or stem with new roots is known as a layer. This type of layering also occurs naturally.
Tubers are vegetative organs that may develop from stems or roots. Stem tubers arise from rhizomes or runners that become swollen from storing nutrients. The upper surface of a tuber produces a new plant shoot system (stems and leaves), while the bottom surface produces a root system. Potatoes and yams are examples of stem tubers. Root tubers originate from roots that have been modified to store nutrients.
Bulbs are the round, swollen parts of a stem that are typically found underground. Within these organs of vegetative propagation lies the central shoot of a new plant. Bulbs consist of a bud that is surrounded by layers of fleshy, scale-like leaves. These leaves are a source of food storage and provide nourishment to the new plant.
Rhizomes are the horizontal stems that grow under the ground. Often sending out roots and shoots from their nodes. If a rhizome is seperated into pieces ,each pieces may be able to give rise to a new plant.
