:It is also called asexual propagation, vegetative reproduction or vegetative multiplication. ... The main difference between natural and artificial vegetative propagation is that natural vegetative propagation naturally occurs in plants whereas artificial vegetative propagation occurs due to the interference of man.

Vegetative reproduction

Vegetative reproduction is a type of asexual reproduction for plants, and is also called vegetative propagation, vegetative multiplication, or vegetative cloning. It is a process by which new plant "individuals" arise or are obtained without production of seeds or spores. It is both a natural process in many plant species (as well as non-plant organisms such as bacteria and fungi) and one used or encouraged by horticulturists to obtain quantities of economically valuable plants.

Natural vegetative reproduction is found primarily in herbaceous and woody perennial plants, and typically involves structural modifications of the stem, although any horizontal, underground part of a plant (whether stem or a root) can contribute to vegetative reproduction of a plant. In a few species, leaves are involved in vegetative reproduction. Most plant species that survive and significantly expand by vegetative reproduction would be perennial almost by definition, since specialized organs of vegetative reproduction, like seeds of annuals, serve to survive seasonally harsh conditions. A plant that persists in a location through vegetative reproduction of individuals over a long period of time constitutes a clonal colony.

In a sense, this process is not one of "reproduction" but one of survival and expansion of biomass of the individual. When an individual organism increases in size via cell multiplication and remains intact, the process is called "vegetative growth." However, in vegetative reproduction, the new plants that result are new individuals in almost every respect except genetic. Of considerable interest is how this process appears to reset the aging clock.

**********************************

Artificial propagation

Reproduction of biological tissues via human intervention, usually under carefully controlled environmental conditions, but in the absence of the usual (generally sexual) modes of reproduction.

Vegetative reproduction can be performed artificially, a common practice among horticulturists, but much vegetative reproduction occurs naturally without human involvement. Furthermore, artificial propagation can be achieved among both animal and plant species, whereas vegetative reproduction only occurs in plants.

Artificial propagation is commonly used to increase the populations of endangered species, often via artificial insemination
