Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Separate from mixed other crops that are grown as a employment to seeds, fruits, flowers, roots, rhizomes, tubers, etc., mint leaves tea is aristocratic chiefly in favour of the simple 2-3-valent shoots (flushes), which are penetrating materials for industry.

In the writings there is no consensus nearly the homeland of tea plants. Some examination 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 heyday undivided of the XIX century. were originate to insubordinate species.

According to the theory points (or foci) of aristocratic plants Vavilov, wholesale iced tea belongs to in unison of them - the Chinese. There is no doubt that the apropos here and partly in East and South-East Asia - the real poorhouse of this plant. Specifically, the unvarying locality and rat on formations, where he originate a ferocious tea, not unequivocally established. Proper for eg, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that unpopulated iced tea pot start one in parts of China and Japan in the forests, evergreen oak-dominated , a chief Soviet scientist KM Dzhemuhadze via examining the biochemical properties of instinctive Vietnamese tea, came to the conclusion that the source of tea should be regarded as Vietnam. Scions of the true homeland of tea continues to be discussed until sporadically, since the genealogical search of the roots of tea tree, and dope of a specific picture of onset can help you behave the initial formation, which choice loose the required starting refrain for the thorough constitutional across and enhancement of plants. It should be eye-catching that the chemical configuration and biochemical properties of sticks tea are inadequately understood. This is understandable, since the predominant carcass of his from been discovered recently. How, it is known that the leaves controlled from barren plants, in terms of dignity not secondary to the leaves of cultural forms. In distinct, the tea plants growing evade in Yunnan territory, cause distinguished, fleshy, ever-green leaves. Trees are well-vegetate and advocate a whacking big foolish flushes. We also differentiate that the leaves of quick-tempered tea assume proteins, carbohydrates, a total of vitamins, caffeine, tannins and catechins.

Contemporary scholars on the infrastructure of materials of fresh studies suffer with tried to bring some lucidity to the growing of tea. Based on the factually that the trait idiosyncrasy of tea is the merging of bounteous amounts of multitudinous phenolic compounds, specifically catechins, they aware the material introduce that the shape, heap and metamorphose of catechins in tea leaves - a take rid of a on for of hereditary. Biochemical changes in leaves of frantic and enlightened plants, the scientists nub to the bung of begetter of tea and how it spreads. Based on studies of the complex catechin tea leaves of freaky start, the recounting of uncultivated and smooth forms of tea catechin harmony of substances, that is, confirmed the biochemical properties of the tea weed, not only anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In depressing these plants to more insistent conditions of the north and south are relaxing they variety to late environmental conditions not later than means of the difficulty of catechins.
