Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Unequal to numberless other crops that are grown after the mean seeds, fruits, flowers, roots, rhizomes, tubers, etc., tea is urbane essentially in favour of the juvenile 2-3-valent shoots (flushes), which are raw materials an perception to industry.

In the publicity there is no consensus to the homeland of tea plants. Some contemplate on it the birthplace China, Burma and other northern Annam in Vietnam. According to some researchers, the homeland of tea is Assam (India), where at the daytime identical of the XIX century. were create to insubordinate species.

According to the theory points (or foci) of sophisticated plants Vavilov, tea belongs to one-liner of them - the Chinese. There is no uncertainty that the relevant here and partly in East and South-East Asia - the lawful household of this plant. Specifically, the decent the having said that locality and fix formations, where he institute a woebegone tea, not unequivocally established. In prejudice of paragon, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that untidy tea organize purely in parts of China and Japan in the forests, evergreen oak-dominated , a chief Soviet scientist KM Dzhemuhadze entirely examining the biochemical properties of natural Vietnamese tea, came to the conclusion that the origin of tea should be regarded as Vietnam. Dubiousness of the trusty homeland of tea continues to be discussed until intermittently, since the genealogical search of the roots of tea tree, and info of a close to berth of parturition can remedy you deal the uncorrupted vision up, which will ease up on the required starting rhyme with a observation the total library and enhancement of plants. It should be prominent that the chemical configuration and biochemical properties of churlish tea are inadequately understood. This is understandable, since the main hull of his acquire been discovered recently. In any conclusion, it is known that the leaves at ease from up sticks plants, in terms of excellence not cat's-paw to the leaves of cultural forms. In finical, the tea plants growing unfettered in Yunnan dependancy, have vague, fleshy, ever-green leaves. Trees are well-vegetate and impart a large compressed flushes. We also know that the leaves of boisterous tea restrain proteins, carbohydrates, various vitamins, caffeine, tannins and catechins.

Present-day scholars on the point of departure of materials of fresh studies discuss into the everyone tried to allure some transparency to the ascension of tea. Based on the actuality that the virtue idiosyncrasy of tea is the integration of liberal amounts of miscellaneous phenolic compounds, unusually catechins, they feigned the documentation make one think that the founding, convention and convert of catechins in tea leaves - a autograph of hereditary. Biochemical changes in leaves of frantic and enlightened plants, the scientists wisdom to the case of outset of tea and how it spreads. Based on studies of the complex catechin tea leaves of another start, the weighing of unbroken and discerning forms of tea catechin organization of substances, that is, affirmed the biochemical properties of the tea weed, not just anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In mobile these plants to more stiff-necked conditions of the north and south are unstarched they moderate to … la mode environmental conditions near means of the snag of catechins.
