Question

Technique of micropropagation

Answer 1

Answer:

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 former two methods need the rooting process with an auxin-like indole acetic acid and with naphthaleneacetic acid thereafter.

Nowadays, the method of propagation from shoots is the most preferred one, because the latter two methods present the possibility of genetic variation owing to the dedifferentiated phase, callus.

Answer 2

The rapid process of vegetative multiplication of plant material in tissue culture and their in vitro propagation technique is called micropropagation. In other words, micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern plant tissue culture methods.
