![]() Since vegetative reproduction is often faster than sexual reproduction, it "quickly increases populations and may contribute to recovery following disturbance" (such as fires and floods). Some analyses suggest that vegetative reproduction is a characteristic which makes a plant species more likely to become invasive. The most common use made of vegetative propagation by forest geneticists and tree breeders has been to move genes from selected trees to some convenient location, usually designated a gene bank, clone bank, clone-holding orchard, or seed orchard where their genes can be recombined in pedigreed offspring. Vegetative reproduction offers research advantages in several areas of biology and has practical usage when it comes to afforestation. In nature, that increases the chances for a plant to successfully reach maturity, and, commercially, it saves farmers a lot of time and money as it allows for faster crop overturn. Vegetative propagation also allows plants to circumvent the immature seedling phase and reach the mature phase faster. However, as can be seen in many variegated plants, this does not always apply, because many plants actually are chimeras and cuttings might reflect the attributes of only one or some of the parent cell lines. For example, developing an ace cultivar is extremely difficult, so, once farmers develop the desired traits in lily, they use grafting and budding to ensure the consistency of the new cultivar and its successful production on a commercial level. Vegetative propagation also allows plants to avoid the costly and complex process of producing sexual reproduction organs such as flowers and the subsequent seeds and fruits. It can be economically beneficial for commercial growers to clone a certain plant to ensure consistency throughout their crops. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. There are several advantages of vegetative reproduction, mainly that the produced offspring are clones of their parent plants. These roots allow for the development of new plants from body parts from other plants. ![]() ![]() Īnother important ability that allows for vegetative propagation is the ability to develop adventitious roots which arise from other vegetative parts of the plants such as the stem or leaves. ![]() The meristem tissue's ability to continuously divide allows for vegetative propagation to occur. It is normally found in stems, leaves, and tips of stems and roots and consists of undifferentiated cells that are constantly dividing allowing for plant growth and give rise to plant tissue systems. Meristem tissue makes the process of asexual reproduction possible. Bulbils are sometimes formed instead of the flowers of garlic. Hawkweed ( Hieracium), dandelion ( Taraxacum), some citrus ( Citrus) and many grasses such as Kentucky bluegrass ( Poa pratensis) all use this form of asexual reproduction. In flowering plants, unfertilized seeds are produced, or plantlets that grow instead of flowers. Apomixis (including apospory and diplospory) is a type of reproduction that does not involve fertilization. In some crops, particularly apples, the rootstocks are vegetatively propagated so the entire graft can be clonal if the scion and rootstock are both clones. In that case, only the top of the plant is clonal. Grafting is often not a complete cloning method because seedlings are used as rootstocks. Thornless blackberry is a chimera, with the epidermal layers genetically thornless but the tissue beneath it genetically thorny. However, root cuttings of thornless blackberries ( Rubus fruticosus) will revert to thorny type because the adventitious shoot develops from a cell that is genetically thorny. Vegetative propagation is usually considered a cloning method. This is because meristematic cells capable of cellular differentiation are present in many plant tissues. Īlthough most plants normally reproduce sexually, many can reproduce vegetatively, or can be induced to do so via hormonal treatments. In general, juveniles of a plant are easier to propagate vegetatively. Vegetative reproduction is favored when it allows plants to produce more offspring per unit of resource than reproduction through seed production. Vegetative reproduction is not evolutionary advantageous it does not allow for genetic diversity and could lead plants to accumulate deleterious mutations. While many plants reproduce by vegetative reproduction, they rarely exclusively use that method to reproduce. 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. Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. |
