उत्तर
Tissue culture is the cultivation of plant parts under the aseptic conditions and suitable nutrient medium. The essential nutrients include inorganic salt, carbon, and energy source and a growth regulator. Applications of tissue culture:
(a) Genetically identical plants are produced from a single cell or a group of cells in a short interval of time by micropropagation. A large number of progeny are produced from a single cell or a group of cells.
(b) It is possible to raise a large number of plants and disease-resistant plants using tissue culture techniques. This method has been used to raise tobacco plants resistant to Wildfire caused by a bacteria pathogen pseudomonas tabaci.
