Plantlets
A plantlet is a young or small plant."Plantlet", Merriam-Webster' Many plants such as spider plants naturally create stolons with plantlets on the ends as a form of asexual reproduction. Vegetative propagules or clippings of mature plants may form plantlets. An example is mother of thousands. Many plants reproduce by throwing out long shoots or runners that can grow into new plants. Mother of thousands appears to have lost the ability to reproduce sexually and make seeds, but transferred at least part of the embryo-making process to the leaves to make plantlets. See also * Apomixis * Plant propagation * Plant reproduction Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from eithe ... References Plants {{Horticulture-stub ...

Mother Of Thousands
''Kalanchoe daigremontiana'', formerly known as ''Bryophyllum daigremontianum'' and commonly called mother of thousands, or Mexican hat plant, is a succulent plant native to Madagascar. Like other members of ''Bryophyllum'' (now included in the genus ''Kalanchoe''), it can propagate vegetatively from plantlets that develop on its leaf margins, as well as through upshoots from lateral roots, and seeds. All parts of this species contain a very toxic steroid known as daigremontianin. It is often confused with ''K. laetivirens'', ''K. delagoensis'' and ''K. × houghtonii''. The leaves of '' K. laetivirens'' are completely green, while ''K. daigremontiana'' has bands or spots on the back of leaves. The leaves of '' K. delagoensis'' are linear, while ''K. daigremontiana'' has lanceolate, oblong, ovate or triangular leaves. '' K. × houghtonii'' is a hybrid between ''K. daigremontiana'' and ''K. delagoensis'', therefore has characteristics in between; its leaves are narrower than thos ...

Chlorophytum Comosum
''Chlorophytum comosum'', usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, ribbon plant (a name it shares with '' Dracaena sanderiana''), and hen and chickens is a species of evergreen perennial flowering plant of the family Asparagaceae. It is native to tropical and Southern Africa, but has become naturalized in other parts of the world, including Western Australia and the Bangladesh., search for "Chlorophytum comosum" ''Chlorophytum comosum'' is easy to grow as a houseplant because of its resilience, but it can be sensitive to the fluoride in tap water, which commonly gives it "burnt tips". Variegated forms are the most popular. Description ''Chlorophytum comosum'' grows to about tall, although as a hanging plant it can descend many feet. It has fleshy, tuberous roots, each about long. The long narrow leaves reach a length of and are around wide. Flowers are produced in a long, branched inflorescence, which can re ...

Bryophyllum Daigremontianum Nahaufnahme2
''Bryophyllum'' (from the Greek ''bryon/bryein'' = sprout, ''phyllon'' = leaf) is a group of plant species of the family Crassulaceae native to Madagascar. It is a section or subgenus within the genus ''Kalanchoe'', and was formerly placed at the level of genus. This section is notable for vegetatively growing small plantlets on the fringes of the leaves; these eventually drop off and root. These plantlets arise from mitosis of meristematic-type tissue in notches in the leaves. Nowadays, bryophyllums are naturalized in many parts of the tropics and subtropics, and deliberately cultivated for their attractiveness or for their interesting reproduction as a vegetative reproductive plant. Taxonomy Species of ''Bryophyllum'' are nested within ''Kalanchoe'' on molecular phylogenetic analysis. Therefore, ''Bryophyllum'' should be a section of ''Kalanchoe'' rather than a separate genus. The number of species within ''Bryophyllum'' varies with definitions of this section. ''Bryo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorophytum Comosum Ampel
''Chlorophytum'' (,''Sunset Western Garden Book,'' 1995:606–607 common name spider plant), is a genus of almost 200 species of evergreen perennial flowering plants in the century plant subfamily within the asparagus family. The plants are native to the tropical and subtropical regions of Africa, Australia, and Asia. They grow to 10–60 cm tall, with a rosette of long, slender leaves 15–75 cm long and 0.5–2 cm broad and thick, fleshy tuberous roots. The flowers are small, usually white, produced on sparse panicles up to 120 cm long; in some species the plants also reproduce vegetatively by means of plantlets, tiny plants that take root on touching the ground. ''Chlorophytum comosum'', the common Spider Plant, a native of South Africa, is a very popular houseplant especially in its variegated form 'Vittatum'. It is commonly grown in hanging pots suspended by ropes or wires in bright sunlight. ''Chlorophytum borivilianum'' is a native of India and it i ...

Stolon
In biology, stolons (from Latin '' stolō'', genitive ''stolōnis'' – "branch"), also known as runners, are horizontal connections between organisms. They may be part of the organism, or of its skeleton; typically, animal stolons are external skeletons. In botany In botany, stolons are stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its clones produced from stolons form a single genetic individual, a genet. Morphology Stolons may or may not have long internodes. The leaves along the stolon are usually very small, but in a few ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asexual Reproduction
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and physically similar to the parent or an exact clone of the parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and eubacteria, bacteria. Many Eukaryote, eukaryotic organisms including plants, animals, and Fungus, fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis, which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. Komodo dragons and some monitor lizards can also reproduce asexually. While all prokaryotes reproduce without the formation and fusion of gametes, m ...

Propagule
In biology, a propagule is any material that functions in propagating an organism to the next stage in its life cycle, such as by dispersal. The propagule is usually distinct in form from the parent organism. Propagules are produced by organisms such as plants (in the form of seeds or spores), fungi (in the form of spores), and bacteria (for example endospores or microbial cysts). In disease biology, pathogens are said to generate infectious propagules, the units that transmit a disease. These can refer to bacteria, viruses, fungi, or protists, and can be contained within host material. For instance, for influenza, the infectious propagules are carried in droplets of host saliva or mucus that are expelled during coughing or sneezing. In horticulture, a propagule is any plant material used for the purpose of plant propagation. In asexual reproduction, a propagule is often a stem cutting. In some plants, a leaf section or a portion of root can be used. In sexual reproduction, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clipping (gardening)
In gardening, clipping is equivalent to pruning, the practice of removing diseases, over mature or otherwise unwanted portions from a plant. Clipping usually involves much less removal than pruning, and is used more for herbaceous (all-green) plants than for wood Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin th ...y ones. References Gardening {{horticulture-stub ...

Apomixis
In botany, apomixis is asexual reproduction without fertilization. Its etymology is Greek for "away from" + "mixing". This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils were categorized as types of apomixis. Apomictically produced offspring are genetically identical to the parent plant. Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes (notably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

Plant Reproduction
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in clonal plants that are genetically identical to the parent plant and each other, unless mutations occur. Asexual reproduction Asexual reproduction does not involve the production and fusion of male and female gametes. Asexual reproduction may occur through budding, fragmentation, spore formation, regeneration and vegetative propagation. Asexual reproduction is a type of reproduction where the offspring comes from one parent only, thus inheriting the characteristics of the parent. Asexual reproduction in plants occurs in two fundamental forms, vegetative reproduction and agamospermy. Vegetative reproduction involves a vegetative piece of ...
