ABSTRACT

Tea, next to water is the beverage humans consume. It is increasingly appreciated that tea contains high amount of polyphenols and other components that may reduce the risk of chronic diseases such as cancer, diabetes etc. Tea has high composition of polyphenols. Catechins are polyphenols which is antioxidant found in tea may reduce the risk of various types of cancers. Several other components also serve as anti – inflammatory effects, enhances cognition in humans. The effect of Thidiazuron (TDZ) on the micro propagation of Camellia sinensis was compared with that of Benzyl Amino Purine (BAP) using nodal segments from in vitro raised seedlings. Extremely low concentrations of TDZ alone were effective in inducing shoot bud proliferation and maintaining high rates of shoot multiplication on hormone-free media. Callus tissues obtained from intact stem segments of tea seedlings. The callus from the epidermal layers form buds. Grafting or graftage is a horticulture technique whereby tissues of plants are joined so as to continue their growth together. The successes of this joining require that the vascular tissue grow together and such joining is called inoculation. The technique is most commonly used in asexual propagation of commercially grown plant for the horticulture and agriculture trades.
