vegetative propagation


Also found in: Medical.

vegetative propagation,

the ability of plants to reproduce without sexual reproduction, by producing new plants from existing vegetative structures. Some plants, such as the Canada thistle and most bamboos, send out long underground stems that produce new plants, often at considerable distances from the original plant. Such plants can form enormous colonies of new plants within a relatively few years. Many trees, such as the beech and aspen, send up root sprouts, and large colonies of new trees thus arise. In other trees, the lower branches may produce roots where they rest upon the ground, and new trees are produced. The leaves of some plants produce buds at their edges, which develop in turn into miniature plants that fall off and take root. Specialists in the fields of agriculture and horticulture take advantage of the regenerative ability of plants through such techniques as the rooting of cuttings; grafting and budding of fruit trees; layering, or inducing the tips of branches to produce new plants; the cutting apart of clusters of perennialsperennial,
any plant that under natural conditions lives for several to many growing seasons, as contrasted to an annual or a biennial. Botanically, the term perennial applies to both woody and herbaceous plants (see stem) and thus includes numerous members of the kingdom.

, such as rhubarb, into individual plants; the cutting of plants (such as the common potato) into pieces that are then planted separately, each with a bud ("eye"); and numerous other techniques. The vegetative propagation of economically important and useful plants is now so widespread that most horticultural varieties are now only reproduced clonally, especially since many of them breed true from seed.

The objective of this study was to evaluate the effect of different substrates and doses of IBA at varying growth periods on the survival and rooting of plant cuttings and on the initial bud growth to establish an effective method for the vegetative propagation of E.
The success of vegetative propagation through cuttings depends on several factors, such as the genetic potential of rooting, physiological conditions of the mother plant, season of year, hormonal balance, temperature, light and humidity (SOUNDY et al.
In vegetative propagation, adventitious root development is a key step which contains root induction, root initiation and projection, related to the emergence of root primordial (Berthon et al.
Vegetative propagation seems to be an excellent tool for the genetic improvement of forest species because it favors the breeding of genetically superior individuals, which results in a greater uniformity in grown plants (Wendling et al.
Vegetative propagation by cuttings: The cuttings produced shoots and leaves within one month, which lasted for three months, at which point they began to wilt.
Vegetative propagation was the technique which was widely used in the field of forestry, agriculture and horticulture for growing choicest plants.
In addition, because the rhizophore is an organ capable of expanding the rhizosphere and conferring resistance and vegetative propagation (Andreata and Menezes, 1999), it is understandable that the rhizophore accumulates large amounts of starch grains, such as the ones regularly found in the cortex and throughout the vascular cylinder of the structure in both studied species.
Thus, this research aimed to verify the efficacy of adding different doses of fungicide to the culture medium, in the contamination of soursop explants cultured in vitro, evaluating the percentage of contamination, as well as the percentage of sprouting by the explants, obtaining information about the viability of its use in a protocol for this species and infer about the possibility of the formation of plants by this method of vegetative propagation.
