When a new plant grows from a fragment or cutting of the parent plant or specialised reproductive structures, which are also called vegetative propagules, it is referred to as vegetative reproduction. [ It is also known as vegetative propagation, vegetative multiplication or cloning.
What is Vegetative Propagation and how does it work
When a plant reproduces through its leaves, roots, or stem, it is referred to as vegetative propagation (asexual reproduction) (asexual reproduction) (asexual reproduction). Specifically, this can occur as a result of the fragmentation and regeneration of specific plant vegetative parts.
Let’s take a closer look at the various types of vegetative propagation and some of their applications.
Various Methods of Vegetative Propagation
Vegetative propagation can be divided into several types, including:
Natural Vegetative Propagation is a method of propagating plants.
This occurs when plants grow and develop in their natural environment, without the interference of humans. The development of adventitious roots can aid in the propagation of plants in their natural environment. This results in the formation of new plants from the roots, stem and leaves of the parent plant.
Rhizomes, bulbs, runners, tubers, and other vegetative plant structures that develop from the stem are known as rhizomes. The following are examples of plants that were propagated vegetatively:
Stem
Runners emerge from the ground in a horizontal fashion. It is at the nodes of the runners that the buds develop.
Tubers are swollen, modified roots that produce new plants when they are exposed to light. Buds form at the base of the stem, near the base of the stem.9
Occasionally, the leaves of a few plants become detached from the parent plant and develop into an entirely new plant.
Bulbs
Flowers have an underground stem to which the leaves are attached, which is known as a bulb. These leaves have the capability of storing food in their cells. The bulb’s centre contains an apical bud, which develops into leaves and flowers as the bulb grows. Shoots are formed as a result of the development of lateral buds.

Artificial Vegetative Propagation (AVP) is a technique for propagating plants in artificial environments.
In both the field and the laboratory, humans are carrying out a type of vegetative reproduction called in vitro fertilisation. The following are the most common types of vegetative reproduction that take place artificially:
Cutting
An individual plant part, such as a stem or leaf, is cut and planted in the soil. Hormones are sometimes applied to these cuttings in order to stimulate root development. The adventitious roots that develop from the cutting become the building blocks of the new plant.
Grafting
Here, the cutting from another plant is attached to the stem of a plant that is rooted in the ground, similar to the method described above. Over time, the tissues of the graft become integrated with the tissues of the rooted plant, and the two plants grow together as a single plant.
Layering
The plant’s stem is bent to the ground and covered with soil in this method. Adventitious roots sprout from the plant parts that have been covered with soil. A layer is the term used to describe this attached stem with developing roots.
Tissue Culture is an abbreviation for tissue culture.
Cell culture is a method of developing a new plant by cultivating plant cells from different parts of the same plant in the laboratory. Increases in the number of rare and endangered plant species that are unable to grow in their natural environment are made possible through the use of this technique.
Various Methods of Vegetative Propagation
Various methods of vegetative propagation are available, including artificial and natural methods. Despite the fact that both methods entail the development of a plant from fragments of a single mature part, the manner in which they are carried out is vastly different.
Artificial Vegetative Propagation (AVP) is a technique for propagating plants in artificial environments.
Artificial vegetative propagation is a type of plant reproduction in which humans are involved in the process of reproduction. The most common types of artificial vegetative reproductive techniques are cutting, layering, grafting, suckering, and tissue culturing, which are all variations on the same theme. In order to produce healthier crops with more desirable characteristics, many farmers and horticulturists use these techniques and methods.
Conclusion
The air plant, Kalanchoe pinnata, produces new individuals along the leaf margins of its leaves. The little plant in front of the door is around 1 cm tall. This process causes the concept of “individual” to be pushed to its limits.
