Keiki Machimura
In horticulture, a keiki ( ) is a plant produced asexually by an orchid plant, especially ''Dendrobium'', ''Epidendrum'' (''sensu lato''), and ''Phalaenopsis'' orchids. The baby plant is an exact clone of the mother plant, sometimes flowering while still attached to the mother. The word ''keiki'' is Hawaiian for "baby" or "child", literally "the little one". *On a ''Phalaenopsis,'' a keiki is a small plant growing from one node along the flower stem. Keiki growth may be induced by prolonged exposure to high temperatures during the final phase of spike growth. *On a ''Dendrobium,'' the keiki is typically found sprouting along the length of the cane or from the end of the cane. In addition to keikis which grow on flower spikes, ''Phalaenopsis'' may occasionally produce basal keikis at the base of the orchid. Removing keikis If a new plant is desired, the keiki should be left on the mother plant until it develops a healthy root system at least 3 inches long and has two or ...

Phalaenopsis Keiki Growth Progression
''Phalaenopsis'' (), also known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines. Description Orchids in the genus ''Phalaenopsis'' are monopodial epiphytic, sometimes lithophytic herbs with long, coarse roots with pneumatodes and short leafy stems hidden by overlapping leaf bases. The leaves are usually arranged in two rows, relatively large and leathery, oblong to elliptic and sometimes succulent. A few to many, small to large, long-lasting, flat, often fragrant flowers are arranged on erect to hanging racemes or panicles. The sepals and petals are free from and spread widely apart from each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchid Biology
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalaenopsis Hieroglyphica
The ornamental orchid species ''Phalaenopsis hieroglyphica'' ( ) is native to certain islands of the Philippines. Its flowers are creamy white with transverse markings that resemble glyphs. Through hybridization, growers have successfully created flowers with different shapes and colors while retaining the glyphs. Since 1975, the species has been protected under Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Growth, habitat and cultivation Commonly ''P. hieroglyphica'' blooms in spring, with three to four star-shaped flowers that open simultaneously and last two to three months; a well-established specimen with keikis can produce more than 50 flowers. Their fragrance is said to be faintly rose-like or strongly citrus-like. The background of the flower can be white to ochre, sometimes with a tinge of green at the tips, and the glyphs on the sepals and stamens can be cinnamon or a purple hue. The flowers are comparativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auxin
Auxins (plural of auxin ) are a class of plant hormones (or plant-growth regulators) with some morphogen-like characteristics. Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development. The Dutch biologist Frits Warmolt Went first described auxins and their role in plant growth in the 1920s. Kenneth V. Thimann became the first to isolate one of these phytohormones and to determine its chemical structure as indole-3-acetic acid (IAA). Went and Thimann co-authored a book on plant hormones, ''Phytohormones'', in 1937. Overview Auxins were the first of the major plant hormones to be discovered. They derive their name from the Greek word αυξειν (''auxein'' – "to grow/increase"). Auxin is present in all parts of a plant, although in very different concentrations. The concentration in each position is crucial developmental information, so it is subject to tight regulation through both meta ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Hormone
A hormone (from the Greek participle , "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs by complex biological processes to regulate physiology and behavior. Hormones are required for the correct development of animals, plants and fungi. Due to the broad definition of a hormone (as a signaling molecule that exerts its effects far from its site of production), numerous kinds of molecules can be classified as hormones. Among the substances that can be considered hormones, are eicosanoids (e.g. prostaglandins and thromboxanes), steroids (e.g. oestrogen and brassinosteroid), amino acid derivatives (e.g. epinephrine and auxin), protein or peptides (e.g. insulin and CLE peptides), and gases (e.g. ethylene and nitric oxide). Hormones are used to communicate between organs and tissues. In vertebrates, hormones are responsible for regulating a variety of physiological processes and behavioral activities such as diges ...

Cytokinin
Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. There are two types of cytokinins: adenine-type cytokinins represented by kinetin, zeatin, and 6-benzylaminopurine, and phenylurea-type cytokinins like diphenylurea and thidiazuron (TDZ). Most adenine-type cytokinins are synthesized in roots. Cambium and other actively dividing tissues also synthesize cytokinins. No phenylurea cytokinins have been found in plants. Cytokinins participate in local and long-distance signalling, with the same transport mechanism as purines and nucleosides. Typically, cytokinins are transported in the xylem. Cytokinins act in concert with auxin, another plant growth hormone. The two are complementary, having generally opposite effects. History The idea of specific substances required for ...

Node (botany)
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaf, leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaf, leaves, conifer cones, or inflorescence, flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flower ...

Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-langua ...
