Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts.
Natural vegetative reproduction is a process mostly found in perennial plants, and typically involves structural modifications of the stem or roots and in a few species leaves. Most plant species that employ vegetative reproduction do so as a means to perennialize the plants, allowing them to survive from one season to the next and often ...
Rose cuttings under plastic bottle greenhouse. Plant roots, stems, and leaves have a number of mechanisms for asexual or vegetative reproduction, which horticulturists employ to multiply or clone plants rapidly, such as in tissue culture and grafting. [7]
These stolons from the corm of a Crocosmia are stems that emerged from axillary buds at the nodes of the tunic leaves. Stolons may have long or short internodes. The leaves along the stolon are usually very small, but in a few cases such as Stachys sylvatica are normal in size. [3] Stolons arise from the base of the plant. [4]
Plants use underground stems to multiply by asexual reproduction and to survive from one year to the next, usually through dormancy. [11] Some plants produce stems modified to store energy and preserve a location of potential growth to survive a cold or dry period which normally is a period of inactive growth, and when that period is over the ...
Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction. [1] Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam.
These stems are called rhizomes. Many fern fronds are initially coiled into a fiddle-head or crozier (see circinate vernation), although cycad and palm fronds do not have this pattern of new leaf growth. Fronds may bear hairs, scales, glands, and, in some species, bulblets for vegetative reproduction.
Plant hormones, termed auxins, are often applied to stem, shoot or leaf cuttings to promote adventitious root formation, e.g., African violet and sedum leaves and shoots of poinsettia and coleus. Propagation via root cuttings requires adventitious bud formation, e.g., in horseradish and apple .
