Nicotiana Tabacum
''Nicotiana tabacum'', or cultivated tobacco, is an annually grown herbaceous plant of the ''Nicotiana'' genus. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 and 2 meters (3' to 6'). Research is ongoing into its ancestry among wild ''Nicotiana'' species, but it is believed to be a hybrid of ''Nicotiana sylvestris'', '' Nicotiana tomentosiformis'', and possibly '' Nicotiana otophora''. It is the most commonly grown of all plants in the genus ''Nicotiana,'' the plants' leaves commercially grown to be processed into tobacco. Description It is an annual plant that grows high and is sticky hairy on all parts. The stems are thick and not very branched. The leaves can be over long with the blades ovate to elliptical, or obovate, pointed towards the front and, at the base, run down the stem or are sessile, encompassing the stem. The scented inflorescences are multi-branched panicles. The flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tobacco Leaves
Tobacco is the common name of several plants in the genus ''Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco".

Nicotiana Attenuata
''Nicotiana attenuata'' is a species of wild tobacco known by the common name coyote tobacco. It is native to western North America from British Columbia to Texas and northern Mexico, where it grows in many types of habitat. It is a glandular and sparsely hairy annual herb exceeding a meter in maximum height. The leaf blades may be long, the lower ones oval and the upper narrower in shape, and are borne on petioles. The inflorescence bears several flowers with pinkish or greenish white tubular throats long, their bases enclosed in pointed sepals. The flower face has five mostly white lobes. The fruit is a capsule about long. Natural history Introduction ''Nicotiana attenuata'' has been utilized as an ecological model species since 1994, thanks in large part to its diverse interactions with a host of different plants, insects, and microorganisms in its native habitat. Work at the Max Planck Institute for Chemical Ecology in Jena, Germany, has been instrumental in integra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicotiana Benthamiana
''Nicotiana benthamiana'', colloquially known as benth or benthi, is a species of ''Nicotiana'' indigenous to Australia. It is a close relative of tobacco. A synonym for this species is ''Nicotiana suaveolens'' var. ''cordifolia'', a description given by George Bentham in ''Flora Australiensis'' in 1868. This was transferred to ''Nicotiana benthamiana'' by Karel Domin in ''Bibliotheca Botanica'' (1929), honoring the original author in the specific epithet. History The plant was used by people of Australia as a stimulant, containing nicotine and other alkaloids, before the introduction of commercial tobacco ('' N. tabacum'' and '' N. rustica''). Indigenous names for it include ''tjuntiwari'' and ''muntju''. It was first collected on the north coast of Australia by Benjamin Bynoe on a voyage of in 1837.

Solanaceae
The Solanaceae , or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida ( dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology. The name Solanaceae derives from the genus ''Solanum''. The etymology of the Latin word is unclear. The name may come from a perceived resemblance of certain solanaceous flowers to the sun and its rays. At least one species of ''Solanum'' is known as the "sunberry". Alternatively, the name could originate from the Latin verb ''sol ...

List Of Tobacco Products
Tobacco is the agricultural product of the leaves of plants in the genus ''Nicotiana'', commonly termed ''tobacco plants''. All species of ''Nicotiana'' contain the addictive drug nicotine—a psychostimulant alkaloid found in all parts of the plants except the seeds, and most heavily-concentrated in the leaves—which occurs in varying amounts depending on the species of ''Nicotiana'' grown; the breed, type, or variety of tobacco cultivated and produced; and the method used to cure and process tobacco leaves once they have been harvested. This article provides a list of tobacco preparations and products. This list includes both tobacco products meant for consumption and those intended for other uses. Under the heading of consumable tobacco products, several categories of tobacco product are described in this list. Of these four basic categories, the first two include what are most often traditional types of tobacco products and preparations, relegated to the broad sub-categ ...

Snuff (tobacco)
Snuff is a smokeless tobacco made from finely ground or pulverized tobacco leaves. The Old Snuff House of Fribourg & Treyer at the Sign of the Rasp & Crown, No.34 James's Haymarket, London, S.W., 1720, 1920. Author: George Evens and Fribourg & Treyer. Publisher: Nabu Press, London, England. Reproduced 5 August 2010, It is inhaled or "sniffed" (alternatively sometimes written as "snuffed") into the nasal cavity, delivering a swift hit of nicotine and a lasting flavored scent (especially if flavoring has been blended with the tobacco). Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made "snuffing" device. Snuff originated in the Americas and was in common use in Europe by the 17th century. Traditional snuff production consists of a lengthy, multi-step process, in tobacco snuff mills. The selected tobacco leaves are first subject to spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
