Problems solved by technology

The disadvantage of this method is the failure to obtain morphogenesis or the formation of amorphous shoots despite the use of different media during the different steps of morphogenesis
[0016] In 1985, Nakamura (Nakamura, Y. The origin of explants on root differentiation in tea plant tissue culture and its effect on different varieties, Shizuoka Tea Experiment Station 62:1-8; 1985) and Palni, Sood, Chand , Sharma, Rao, and Jain (Palni, L.M.S. Sood, A. Chand, G. Sharma, M. Rao, D.V. Jain, N.K. Tissue Culture Studies in Tea, Proc. International Sym. About Tea Science, Shizuoka, Japan, 395- 399, 1991) also tried plant regeneration via callus phase leaf explants, wherein rooting or root formation was obtained from leaf callus, but the disadvantage was that this rooting callus did not produce roots and using two different media

Embodiment 2

[0061] Complete folding with 50-year-old selected plants of any important cultivar (China, Assamica and Cambod) from Himalayan Bioresource Technology Experimental Farm Institute, Banuri, Palampur (36°N and 78.18°E and sea level above 1290m) Leaves from open, semi-open or fully-open leaf explants (second and third leaves from the tip of young shoots) were used as explants. The leaves were washed thoroughly with a brush made of sable hair and liquid detergent, washed in Tween 20 containing (0.1%) carbendazim and (0.05%) streptomycin and washed in 0.01 % mercuric chloride solution followed by a thorough rinse in distilled water. The sterilized explants were cultured similarly to every detail in the method described above.

Abstract

The invention provides a method of breeding tea trees from microbody of leaf explantation of callus phase. During the period from induction of callus to taking root and sprouting, putting the explant into basic medium of Murashige and Skoog maintained for 14--16 weeks, said medium is supplemented with vitamine such as vitamine B1-HCI(0.05-2.0 mg / I), vitamine B6-HCI(0.25-1.5 mg / ml), and niacin (0.25-1.5 mg / ml) and glycocoll (1.0-3.0 mg / I) ect.

Description

technical field [0001] The invention relates to a new one-step method for producing micro-sprouts from tea tree leaves. Background technique [0002] Tea is a popular caffeinated beverage with anticancer properties (Jankun et al., Why Tea Drinking May Prevent Cancer, Nature 5:561; 1997). Although there are many species of Camellia, only C. sinensis (L.) O. Kuntze or tea and its different cultivars such as Chinary, Assamica and Cambod are commercially important (Braua D.N. "The Tea Tree Trade" in Barua D.N. ed., Science and Practice in Tea Cultivation, Calcutta Tea Research Association; 53-68; 1989). [0003] Tea cultivation is not only an important source of employment but also a major means of earning foreign exchange in all tea-growing regions of the world ("Botany and Plant Improvement" in Coffee, Cocoa and Tea, edited by Wilson, K.C., CABI Publishing, Wallingford , UK: 167-173; 1999). However, the total production of tea is not enough to meet the needs of the country ...
