Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from adventitious buds on the roots of a tree or shrub, which may be called root sprouts or suckers. A plant that produces root sprouts or runners is described as surculose. Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub. TOC In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the base of the originating plant, are a form of vegetative dispersal, and may form a patch that constitutes a habitat in which that surculose plant is the dominant species. Root sprouts also may grow from the roots of trees that have been felled. Tree roots ordinarily grow outward from their trunks a distance of 1.5 to 2 times their heights, and therefore root sprouts can emerge a substantial distance from the trunk. This is a phenomenon of natural "asexual reproduction", also denominated "vegetative reproduction". It is a strategy of plant propagation. The complex of clonal individuals and the originating plant comprise a single genetic individual, i. e., a genet. The individual root sprouts are clones of the original plant, and each has a genome that is identical to that of the originating plant from which it grew. Many species of plants reproduce through vegetative reproduction, e. g. Canada thistle, cherry, apple, guava, privet, hazel, lilac, tree of heaven, and Asimina triloba. The root sprout is a form of dispersal vector that allows plants to spread to habitats that favor their survival and growth.

Grafting

Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion (ˈsaɪən) while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together. The natural equivalent of this process is inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades.

Clonal colony

A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil. Clonal colonies are common in many plant species.

Tree

In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight.
