Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
The only known natural example of King's Lomatia (Lomatia tasmanica) found growing in the wild is a clonal colony in Tasmania estimated to be 43,600 years old. [1]A group of 47,000 Quaking Aspen (Populus tremuloides) trees (nicknamed "Pando") in the Wasatch Mountains, Utah, United States, has been shown to be a single clone connected by the root system.
The most common form of plant reproduction used by people is seeds, but a number of asexual methods are used which are usually enhancements of natural processes, including: cutting, grafting, budding, layering, division, sectioning of rhizomes, roots, tubers, bulbs, stolons, tillers, etc., and artificial propagation by laboratory tissue cloning.
Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Plant propagation can refer to both man-made and natural processes.
Many plants are well known for natural cloning ability, including blueberry plants, Hazel trees, the Pando trees, [10] [11] the Kentucky coffeetree, Myrica, and the American sweetgum. It also occurs accidentally in the case of identical twins, which are formed when a fertilized egg splits, creating two or more embryos that carry identical DNA.
Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [clarification needed] Differences in growth were detected early in ontogeny. The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by ...
Swedish conifers orchards with tested clones could have 20–25 clones with more ramets from the better and less from the worse so effective ramet number is 15–18. Higher clone number results in unneeded loss of genetic gain. Lower clone numbers can still be better than existing alternatives.
Artificial reproduction is the re-creation of life brought about by means other than natural ones. It is new life built by human plans and projects. Examples include artificial selection, artificial insemination, in vitro fertilization, artificial womb, artificial cloning, and kinematic replication.
