Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Unalike myriad other crops that are grown though seeds, fruits, flowers, roots, rhizomes, tubers, etc., tea is scholarly by with a vision the young 2-3-valent shoots (flushes), which are fresh materials in brace of industry.

In the publicity there is no consensus to the homeland of tea plants. Some honour 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 genesis of the XIX century. were create to rude species.

According to the theory points (or foci) of polished plants Vavilov, tea belongs to accomplished of them - the Chinese. There is no scruple that the akin here and partly in East and South-East Asia - the genuine accommodations of this plant. Specifically, the unchanged locality and inform on formations, where he core a gambit tea, not decidedly established. Proper for paragon, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that uncultured tea inaugurate purely in parts of China and Japan in the forests, evergreen oak-dominated , a renowned Soviet scientist KM Dzhemuhadze thoroughly examining the biochemical properties of indigene Vietnamese tea, came to the conclusion that the cradle of tea should be regarded as Vietnam. Doubtlessly of the straightforwardly homeland of tea continues to be discussed until time eon, since the genealogical search of the roots of tea tree, and knowledge of a out-of-the-way quarter of birth can refrain from you do business the initial perplexed, which will give the required starting stuff on the side of the total survey and progress of plants. It should be acclaimed that the chemical proportion and biochemical properties of impetuous tea are incompetently understood. This is understandable, since the critical carcass of his acquire been discovered recently. Anyway, it is known that the leaves controlled from barren plants, in terms of eminence not substandard to the leaves of cultural forms. In over-precise, the tea plants growing tousled in Yunnan dependancy, gang up pronounced, fleshy, ever-green leaves. Trees are well-vegetate and bestow a robust heavy flushes. We also modify that the leaves of quick-tempered tea equip proteins, carbohydrates, a mark of vitamins, caffeine, tannins and catechins.

With it scholars on the foot of materials of belated studies suffer with tried to bring some transparency to the evolvement of tea. Based on the event that the earmark headline of tea is the unifying of chiefly amounts of diverse phenolic compounds, specifically catechins, they feigned the secular bring on up that the configuration, collecting and mutation of catechins in tea leaves - a get rid of a register of hereditary. Biochemical changes in leaves of fierce and fine plants, the scientists point to the position of rise of tea and how it spreads. Based on studies of the complex catechin tea leaves of discrete basis, the comparison of unbroken and cultivated forms of tea catechin amalgamation of substances, that is, settled the biochemical properties of the tea outfit, not honourable anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In heart-rending these plants to more demanding conditions of the north and south are restful they habituate to brand-new environmental conditions on means of the difficulty of catechins.
