The history of plant tissue culture begins … … Academia.edu no longer supports Internet Explorer. Micropropagation techniques are of three types based on the way of propagation: first, the propagation from shoots with cytokinin like benzyladenine or kinetin; second, multiple shoot differentiation from dedifferentiating tissue, callus, with an auxin-like indole acetic acid; and finally, the embryo differentiation from callus. The commercial technology is primarily based on micropropagation, in which rapid proliferation is achieved from tinystem cuttings, axillary buds, and to a limited Tissue culture is seen as an important technology for developing countries for the production of disease-free, high quality planting material and the rapid production of many uniform plants. All tissue cultures start life as a small cutting from a sample. Tissue culture is a very fast technique. Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. The method offers an advantage over other methods as it can be used to develop disease free plants from disease-rode plants by using their meristems (apical and axillary) as explants.
