Onions
An onion (''Allium cepa'' L., from Latin ''cepa'' meaning "onion"), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus '' Allium''. The shallot is a botanical variety of the onion which was classified as a separate species until 2010. Its close relatives include garlic, scallion, leek, and chive. This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (''Allium fistulosum''), the tree onion (''A.'' × ''proliferum''), and the Canada onion (''Allium canadense''). The name '' wild onion'' is applied to a number of ''Allium'' species, but ''A. cepa'' is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pickled Onion
Pickled onions are a food item consisting of onions (cultivars of '' Allium cepa'') pickled in a solution of vinegar and salt, often with other preservatives and flavourings. Channel 4 Recipes - Pickled Onions Retrieved 26 May 2014 There is a variety of small white pickled onions known as 'silverskin' onions; due to imperfections they are pickled instead of being wasted. They are frequently used as an essential component of the variant known as a |
Tree Onion
The tree onion (''Allium'' × ''proliferum'') is a perennial plant similar to the common onion (''A. cepa''), but with a cluster of bulblets where a normal onion would have flowers. Tree onions are also known as topsetting onions, walking onions, or Egyptian onions. Genomic evidence has conclusively shown that they are a diploid hybrid of the shallot and the Welsh onion (''A. fistulosum''). However, some sources may still treat the tree onion as ''A. cepa'' var. ''proliferum'' or ''A. cepa'' Proliferum Group. Tree onion bulblets will sprout and grow while still on the original stalk. The bulblets are usually marble-sized, between 0.5 cm to 3 cm in diameter. They may bend down under the weight of the new growth and take root some distance from the parent plant, giving rise to the name "walking onion". It has been postulated that the name "Egyptian onion" derived from Romani people bringing tree onions to Europe from the Indian subcontinent. The p ...

Scallion
Scallions (also known as spring onions or green onions) are vegetables derived from various species in the genus '' Allium''. Scallions generally have a milder taste than most onions and their close relatives include garlic, shallot, leek, chive, and Chinese onions. Although the bulbs of many ''Allium'' species are used as food, the defining characteristic of scallion species is that they lack a fully developed bulb. Instead the ''Allium'' species referred to as scallions make use of the hollow, tubular green leaves growing directly from the bulb. These leaves are used as a vegetable and can be eaten either raw or cooked. Often the leaves are chopped into other dishes and used as garnishes. Etymology and names The words ''scallion'' and ''shallot'' are related and can be traced back to the Ancient Greek () as described by the Greek writer Theophrastus. This name, in turn, is believed to originate from the name of the ancient Canaanite city of Ashkelon. Various other na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shallot
The shallot is a botanical variety (a cultivar) of the onion. Until 2010, the (French red) shallot was classified as a separate species, ''Allium ascalonicum''. The taxon was synonymized with '' Allium cepa'' (the common onion) in 2010, as the difference was too small to justify a separate species. As part of the onion genus ''Allium'', its close relatives include garlic, scallions, leeks, chives, and the Chinese onion. Names The name "shallot" comes from Ashkelon, an ancient Canaanite city, where Classical-era Greeks believed shallots originated. The term ''shallot'' is usually applied to the French red shallot (''Allium cepa'' var. ''aggregatum'', or the ''A. cepa'' Aggregatum Group). It is also used for the Persian shallot or ''musir'' (''A. stipitatum'') from the Zagros Mountains in Iran and Iraq, and the French gray shallot (''Allium oschaninii'') which is also known as ''griselle'' or "true shallot"; it grows wild from Central to Southwest Asia.

Allium Fistulosum
''Allium fistulosum'', the Welsh onion, also commonly called bunching onion, long green onion, Japanese bunching onion, and spring onion, is a species of perennial plant, often considered to be a kind of scallion. The species is very similar in taste and odor to the related common onion, ''Allium cepa'', and hybrids between the two (tree onions) exist. ''A. fistulosum'', however, does not develop bulbs, and possesses hollow leaves (''fistulosum'' means "hollow") and scapes. Larger varieties of ''A. fistulosum'', such as the Japanese ''negi'', resemble the leek, whilst smaller varieties resemble chives. ''A. fistulosum'' can multiply by forming perennial evergreen clumps. It is also grown in a bunch as an ornamental plant. Names The common name "Welsh onion" does not refer to Wales but derives from a near obsolete use of "Welsh" in the sense "foreign, non-native", as the species is native to China, though cultivated in many places and naturalized in scattered locations i ...

Vegetable
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses. Originally, vegetables were collected from the wild by hunter-gatherers and entered cultivation in several parts of the world, probably during the period 10,000 BC to 7,000 BC, when a new agricultural way of life developed. At first, plants which grew locally would have been cultivated, but as time went on, trade brought exotic crops from elsewhere to add to domestic types. Nowadays, ...

Allium
''Allium'' is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name ''Allium'' is the Latin word for garlic,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 43 and the type species for the genus is ''Allium sativum'' which means "cultivated garlic".''Allium'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below). Carl Linnaeus first described the genus ''Allium'' in 1753. Some sources refer to Greek ἀλέω (aleo, to avoid) by reason of the smell of garlic. Various ''Allium'' have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants. The decision to include a species in the genus ''Allium'' is taxonomically difficult, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allium Canadense
''Allium canadense'', the Canada onion, Canadian garlic, wild garlic, meadow garlic and wild onion is a perennial plant native to eastern North America from Texas to Florida to New Brunswick to Montana. The species is also cultivated in other regions as an ornamental and as a garden culinary herb. The plant is also reportedly naturalized in Cuba. Description ''Allium canadense'' has an edible bulb covered with a dense skin of brown fibers. The plant also has strong onion odor and taste. Crow garlic ('' Allium vineale'') is similar, but it has a strong garlic taste. The narrow, grass-like leaves originate near the base of the stem, which is topped by a dome-like cluster of star-shaped, pink or white flowers. These flowers may be partially or entirely replaced by bulblets. When present, the flowers are hermaphroditic (both male and female organs) and are pollinated by American bees (not honeybees) and other insects. It typically flowers in the spring and early summer, from May to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ditylenchus Dipsaci
''Ditylenchus dipsaci'' is a plant pathogenic nematode that primarily infects onion and garlic. It is commonly known as the stem nematode, the stem and bulb eelworm, or onion bloat (in the United Kingdom).''Ditylenchus dipsaci'' at European and Mediterranean Plant Protection Organization Symptoms of infection include stunted growth, discoloration of bulbs, and swollen stems. ''D. dipsaci'' is a migratory endoparasite that has a five-stage lifecycle and the ability to enter into a dormancy stage. ''D. dipsaci'' enters through stomata or plant wounds and creates galls or malformations in plant growth. This allows for the entrance of secondary pathogens such as fungi and bacteria. Management of disease is maintained through seed sanitation, heat treatment, crop rotation, and fumigation of fields. ''D. ...

Chive
Chives, scientific name ''Allium schoenoprasum'', is a species of flowering plant in the family Amaryllidaceae that produces edible leaves and flowers. Their close relatives include the common onions, garlic, shallot, leek, scallion, and Chinese onion. A perennial plant, it is widespread in nature across much of Europe, Asia, and North America. ''A. schoenoprasum'' is the only species of ''Allium'' native to both the New and the Old Worlds.Ernest Small James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) Chives are a commonly used herb and can be found in grocery stores or grown in home gardens. In culinary use, the green stalks ( scapes) and the unopened, immature flower buds are diced and used as an ingredient for omelettes, fish, potatoes, soups, and many other dishes. The edible flowers can be used in salads. Chives have insect-repelling properties that can be used in gardens to control pests. The plant provides a great deal of nectar for pollinators. ...

Leek
The leek is a vegetable, a cultivar of '' Allium ampeloprasum'', the broadleaf wild leek ( syn. ''Allium porrum''). The edible part of the plant is a bundle of leaf sheaths that is sometimes erroneously called a stem or stalk. The genus '' Allium'' also contains the onion, garlic, shallot, scallion, chive, and Chinese onion. Three closely related vegetables, elephant garlic, kurrat and Persian leek or ''tareh'', are also cultivars of ''A. ampeloprasum'', although different in their uses as food. Etymology Historically, many scientific names were used for leeks, but they are now all treated as cultivars of ''A. ampeloprasum''. The name ''leek'' developed from the Old English word , from which the modern English name for garlic also derives. means 'onion' in Old English and is a cognate with languages based on Old Norse; Danish ', Icelandic ', Norwegian ' and Swedish '. German uses ' for leek, but in Dutch, ' is used for the whole onion genus, Allium. Form Rather t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delia Antiqua
''Delia antiqua'', commonly known as the onion fly, is a cosmopolitan pest of crops. The larvae or maggots feed on onions, garlic, and other bulbous plants. Morphology and biology The onion fly has an ash-grey body and resembles a housefly. The male has a longitudinal stripe on the abdomen which is lacking in the female. The legs are black, the wings transparent, and the compound eyes brown. The eggs are white and elongated and are laid in groups on the shoots, leaves, and bulbs of host plants and on the ground nearby. The larvae are white and cylindrical and hatch in 3 to 8 days. Each batch of larvae tends to keep together and collectively create large cavities in bulbs. More than 50 maggots may feed on one bulb, sometimes originating from eggs laid by several females. The larvae moult three times, feed for about 20 days, and grow to about 1.0 cm long. The pupa is brown, ringed, and ovoid and measures long. Pupation occurs in the ground with the pupal phase from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
