Karat Banana
Karat bananas are local cultivars of Fe'i banana found in Pohnpei, Federated States of Micronesia. The name originates from their bright orange flesh, unusually rich in β-carotene. They are often treated as a single cultivar, i.e. a distinct cultivated variety, with a name written as ''Musa'' 'Karat' in accordance with the International Code of Nomenclature for Cultivated Plants. However, in Pohnpei there are at least three types, 'Karat Kole', 'Karat Pwehu' and 'Karat Pako'. The last has a larger fruit, up to 400–500 g in weight. Traditionally, the Karat banana was used in Micronesia to wean infants onto solid food. It is much less often eaten there now that imported foods have grown in popularity. However, it is believed that because beta-carotenes are important metabolic precursors of vitamin A, essential for the proper functioning of the retina, giving Karat bananas to young children could help ward off certain kinds of blindness Visual or vision impairment (VI o ...

Musa (genus)
''Musa'' is one of three Genus, genera in the family Musaceae. The genus includes 83 species of flowering plants producing edible bananas and Cooking banana, plantains, and fiber (abacá), used to make paper and cloth. Though they grow as high as trees, banana and plantain plants are not woody and their apparent "Plant stem, stem" is made up of the bases of the huge leaf Petiole (botany), stalks. Thus, they are technically gigantic herbaceous plants. Description Banana plants are among the largest extant herbaceous plants, some reaching up to in height or in the case of ''Musa ingens''. The large herb is composed of a modified underground stem (rhizome), a false trunk or pseudostem formed by the basal parts of tightly rolled leaves, a network of roots, and a large flower spike. A single leaf is divided into a leaf sheath, a contracted part called a Petiole (botany), petiole, and a terminal leaf blade. The false trunk is an aggregation of leaf sheaths; only when the plant is r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fe'i Banana
Fe'i bananas (also spelt Fehi or Féi) are cultivated plants in the genus ''Musa (genus), Musa'', used mainly for their fruit. They are very distinct in appearance and origin from the majority of bananas and True plantains, plantains currently grown. Found mainly in the islands of the Pacific, particularly French Polynesia, Fe'i bananas have skins which are brilliant orange to red in colour with yellow or orange flesh inside. They are usually eaten cooked and have been an important food for Pacific Islanders, moving with them as they migrated across the ocean. Most are high in beta-Carotene, ''beta''-carotene (a precursor of vitamin A). The botanical name for Fe'i bananas is ''Musa'' × ''troglodytarum'' L. Precisely which wild species they are descended from is unclear. Description Fe'i bananas are cultivated varieties (cultivars), rather than wild forms. They are distinctly different from the much more common bananas and True plantains, plantains derived from ''Musa acuminata ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pohnpei
Pohnpei (formerly known as Ponape or Ascension, from Pohnpeian: "upon (''pohn'') a stone altar (''pei'')") is an island of the Senyavin Islands which are part of the larger Caroline Islands group. It belongs to Pohnpei State, one of the four states in the Federated States of Micronesia (FSM). Major population centers on Pohnpei include Palikir, the FSM's capital, and Kolonia, the capital of Pohnpei State. Pohnpei is the largest island in the FSM, with an area of , and a highest point of , the most populous with 36,832 people, and the most developed single island in the FSM. Pohnpei is home to the megaliths and ruined city of Nan Madol, built of artificial islands off the island's eastern shore beginning in the 8th or 9th century. An important archaeological site, it was declared a national historic site in 1985. Pohnpei contains a wealth of biodiversity. It is one of the wettest places on Earth with annual recorded rainfall exceeding each year in certain mountainous loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federated States Of Micronesia
The Federated States of Micronesia (, abbreviated FSM), or simply Micronesia, is an island country in Micronesia, a region of Oceania. The federation encompasses the majority of the Caroline Islands (excluding Palau) and consists of four Administrative divisions of the Federated States of Micronesia#States, states—from west to east: Yap State, Yap, Chuuk State, Chuuk, Pohnpei State, Pohnpei, and Kosrae—that span the western Pacific just north of the equator for a Longitude, longitudinal distance of almost . Together, the states comprise around 607 islands and a combined land area of approximately . The entire island nation lies across the northern Pacific accordingly: northeast of Indonesia and Papua New Guinea, south of Guam and the Marianas, west of Nauru and the Marshall Islands, east of Palau and the Philippines, about north of eastern Australia, southeast of Japan, and some southwest of Honolulu of the Hawaiian Islands.

International Code Of Nomenclature For Cultivated Plants
The ''International Code of Nomenclature for Cultivated Plants'' (ICNCP) is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity. It is also known as Cultivated Plant Code. Cultigens under the purview of the ICNCP include ''cultivars'', Groups (''cultivar groups''), and '' grexes''. All organisms traditionally considered to be plants (including algae and fungi) are included. Taxa that receive a name under the ''ICNCP'' will also be included within taxa named under the International Code of Nomenclature for algae, fungi, and plants, for example, a cultivar is a member of a species. Brief history The first edition of the ''ICNCP'', which was agreed in 1952 in Wageningen and published in 1953, has been followed by seven subsequent editions – in 1958 (Utrecht), 1961 (update of 1958), 1969 (Edinburgh), 1980 (Seattle), 1995 (Edinburgh), 2004 (Toronto) and 2009 (Wageningen).

Vitamin A
Vitamin A is a fat-soluble vitamin that is an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinyl esters, and several provitamin (precursor) carotenoids, most notably Β-Carotene, β-carotene (''beta''-carotene). Vitamin A has multiple functions: growth during embryo development, maintaining the immune system, and healthy vision. For aiding vision specifically, it combines with the protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A occurs as two principal forms in foods: A) retinoids, found in Animal source foods, animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids Α-Carotene, α-carotene (''alpha''-carotene), β-carotene, Γ-Carotene, γ-carotene (''gamma''-carotene), and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that ...

Retina
The retina (; or retinas) is the innermost, photosensitivity, light-sensitive layer of tissue (biology), tissue of the eye of most vertebrates and some Mollusca, molluscs. The optics of the eye create a focus (optics), focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception. The retina serves a function which is in many ways analogous to that of the photographic film, film or image sensor in a camera. The neural retina consists of several layers of neurons interconnected by Chemical synapse, synapses and is supported by an outer layer of pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rod cell, rods and cone cell, cones. Rods function mainly in dim light and provide monochromatic vision. Cones function in well-lit conditions and are responsible fo ...

Blindness
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking. The terms ''low vision'' and ''blindness'' are often used for levels of impairment which are difficult or impossible to correct and significantly impact daily life. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems. The most common causes of visual impairment globally are uncorrected refractive errors (43%), cataracts (33%), and glaucoma (2%). Refractive errors include near-sightedness, far-sightedness, presbyopia, and astigmatism (eye), astigmatism. Cataracts are the most common cause of blindness. Other disorders that may cause visual problems include age-related macular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
