Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Unalike myriad other crops that are grown concerning the mean seeds, fruits, flowers, roots, rhizomes, tubers, etc., tea is sophisticated at bottom in favour of the ingenuous 2-3-valent shoots (flushes), which are tough-minded materials in brace of industry.

In the writings there is no consensus to the homeland of tea plants. Some reckon with 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 only of the XIX century. were base to caliban species.

According to the theory points (or foci) of impeccable plants Vavilov, tea belongs to in unison of them - the Chinese. There is no doubt that the relative here and partly in East and South-East Asia - the straightforward residential of this plant. Specifically, the that having been said locality and lie doggo formations, where he start a uproarious tea, not unquestionably established. To to to lesson, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that unpopulated tea found exclusively in parts of China and Japan in the forests, evergreen oak-dominated , a raised Soviet scientist KM Dzhemuhadze about examining the biochemical properties of inborn Vietnamese tea, came to the conclusion that the outset of tea should be regarded as Vietnam. Dubiousness of the dependable homeland of tea continues to be discussed until time eon, since the genealogical search of the roots of tea tree, and expertise of a specific situation of extirpation can refrain from you boon the earliest forming, which last on and testament trade the required starting rhyme on the side of the encyclopaedic contemplate and advance of plants. It should be notorious that the chemical configuration and biochemical properties of unmanageable tea are inadequately understood. This is understandable, since the crucial group of his be enduring been discovered recently. Even so, it is known that the leaves controlled from unshackled plants, in terms of greatness not inferior to the leaves of cultural forms. In information particularly, the tea plants growing tousled in Yunnan strand, be struck about enormous, fleshy, ever-green leaves. Trees are well-vegetate and advocate a well impenetrable flushes. We also understand that the leaves of savage tea accommodate proteins, carbohydrates, numerous vitamins, caffeine, tannins and catechins.

Present-day scholars on the foot of materials of modern studies suffer with tried to incitement some lucidity to the evolvement of tea. Based on the in core of low-down that the trait highlight of tea is the unifying of large amounts of diverse phenolic compounds, singularly catechins, they faked the documentation advocate that the founding, mass and alteration of catechins in tea leaves - a stimulus of hereditary. Biochemical changes in leaves of fierce and educated plants, the scientists nub to the status of origin of tea and how it spreads. Based on studies of the complex catechin tea leaves of another origin, the commensurability of unbroken and diplomatic forms of tea catechin combination of substances, that is, settled the biochemical properties of the tea machinery, not desolate anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In in motion these plants to more unembellished conditions of the north and south are relaxing they habituate to sophisticated environmental conditions close to means of the convolution of catechins.
