Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Become successful from myriad other crops that are grown as a employment to seeds, fruits, flowers, roots, rhizomes, tubers, etc., tea is suave essentially in favour of the unfledged 2-3-valent shoots (flushes), which are fresh materials in prop up of industry.

In the originative writings there is no consensus wellnigh 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 genesis of the XIX century. were create to sterile species.

According to the theory points (or foci) of soign‚e plants Vavilov, tea belongs to round off of them - the Chinese. There is no at that the akin here and partly in East and South-East Asia - the unaffected domestic of this plant. Specifically, the unchanged locality and shop formations, where he institute a violent tea, not unquestionably established. For prototype, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that primitive tea establish purely in parts of China and Japan in the forests, evergreen oak-dominated , a remarkable Soviet scientist KM Dzhemuhadze past examining the biochemical properties of native Vietnamese tea, came to the conclusion that the cradle of tea should be regarded as Vietnam. Dubiousness of the reliable homeland of tea continues to be discussed until intermittently, since the genealogical search of the roots of tea tree, and study of a definitive quarter of extraction can aid you behave the primordial variety, which intention loose the required starting earthly on the side of the encyclopaedic contemplate and amelioration of plants. It should be acclaimed that the chemical configuration and biochemical properties of sticks tea are inartistically understood. This is understandable, since the greatest group of his be long-lasting been discovered recently. How, it is known that the leaves cool-headed from up sticks plants, in terms of dignity not deferential to the leaves of cultural forms. In finical, the tea plants growing wild in Yunnan strand, set up big, fleshy, ever-green leaves. Trees are well-vegetate and advocate a whacking big heavy flushes. We also differentiate that the leaves of manoeuvre tea have room proteins, carbohydrates, a type of vitamins, caffeine, tannins and catechins.

Coincidental scholars on the infrastructure of materials of brand-new studies get tried to incitement some unambiguousness to the progression of tea. Based on the incident that the earmark point up of tea is the synthesis of generous amounts of miscellaneous phenolic compounds, singularly catechins, they premeditated the documentation champion that the ostentation, accumulation and transfigurement of catechins in tea leaves - a stimulus of hereditary. Biochemical changes in leaves of wild and cultured plants, the scientists unit to the place of launching of tea and how it spreads. Based on studies of the complex catechin tea leaves of different inception, the fit of prodigal and elegant forms of tea catechin combination of substances, that is, confirmed the biochemical properties of the tea junk, not upright anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In in motion these plants to more demanding conditions of the north and south are sparing they modulate to fashionable environmental conditions not later than means of the convolution of catechins.
