Cannabis has long been used for hemp fibre, for hemp oils, for medicinal purposes, and as a recreational drug.

However, the serration vein originates from lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. The authors hypothesized that the two subspecies diverged primarily as a result of human selection; C. sativa was presumably selected for traits that enhance fiber or seed production, whereas C. Molecular analytical techniques developed in the late 20th century are being applied to questions of taxonomic classification. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting a high degree of potential variation for selection, even in heavily selected hemp cultivars. In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa.
This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. This has resulted in many reclassifications based on evolutionary systematics. They also commented that these analyses confirm the continuity of the Cannabis gene pool throughout the studied accessions, and provide further confirmation that the genus consists of a single species, although theirs was not a systematic study per se. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from the other putative taxa. He also concluded there is little support to treat C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.
Various compounds, including hashish and hash oil, are extracted from the plant. as a wild or escaped variety of the high-intoxicant type.
The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters. According to Schultes' and Anderson's descriptions, C.
At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. as a wild or escaped variety of low-intoxicant Cannabis, and C. Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. sativa is tall and laxly branched with relatively narrow leaflets, C.
The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C.In 1545 cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. Cannabis is used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.In North America cannabis, in the form of hemp, was grown for use in rope, clothing and paper. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. The term hemp is used to name the durable soft fiber from the Cannabis plant stem (stalk).Tiny samples of Cannabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment. The botanists engaged in heated debate (outside of court), and both camps impugned the other's integrity. They used gas chromatography to determine cannabinoid content and to infer allele frequencies of the gene that controls CBD and THC production within the studied populations, and concluded that the patterns of cannabinoid variation support recognition of C. Cannabis aficionados recognize three distinct types based on such factors as morphology, native range, aroma, and subjective psychoactive characteristics.The plant is believed to have originated in the mountainous regions northwest of the Himalayas. sativa proved too unwieldy, and never gained many adherents. and American taxonomist Arthur Cronquist published a taxonomic revision that recognizes a single species of Cannabis with two subspecies: C. Sativa is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions.Recent phylogenetic studies based on cp DNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former Celtidaceae family, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato. The psychoactive effects of cannabis are known to have a biphasic nature.Tags: Adult Dating, affair dating, sex dating
