Introduction:
Plant tissue culture is the technique of in vitro maintaining and growing cells, tissues and organs etc and their differences on artificial medium under asceptic conditions inside suitable containers. Tissue Culture technique watch first practiced by Haberlandt in 1902 and Hanning. Is traditional breeding techniques failed to keep pace be demand and to provide sufficiently fast and efficient system for crop improvement under technology called tissue culture got developed.
It was learnt by scientist during 1950 that whole plants could be regenereted from explants, any part of a plant taken out and grown in a test tube, sterile conditions in special nutrient media. This capacity to generate a whole plant from any cell / explant is called Totipotency. Important to stress here that the nutrient medium must provide a carbon source such as sucrose and also inorganic salts, vitamins, amino acids and growth regulators like auxins, cytokinins. By application of these methods it is possible to achieve propagation a very large number of plants in very short durations. This method of producing thousands of plants through tissue culture is called micropropagation.
