Micropropagation -

Regeneration of a whole plant through tissue culture is popularly called micropropagation. Within a very short time and space, a large number of plantlets can be produced from callus tissue. Again, it is possible to make a large number of callus pieces from the original stock culture during sub culturing.

Then it is possible to produce hundreds of plantlets that develop on each of these callus pieces. Therefore, the most obvious advantage of micropropagation is numerical as numerous cell aggregates can be produced relatively rapidly, generally growing faster than callus tissues. The number of plantlets produced depends on the number of shoot primordia that can be induced to form within these cell aggregates.
