Meaning of Micro Propagation
In nature, the method of plant propagation may be either asexual (by multiplication of vegetation parts) or sexual (through generation of seed ). Sexually propagated plants show a high degree from inbreds lines. Asexual reproduction , on the other hand, gives rise to plants which are genetically identical to the parent plants and thus permits perpetuation of the unique characters of the cultivars.
Multiplication of genetically identical copies of a cultivar by asexual reproduction is called clonal propagation.
“Clonal propagation through tissue culture technique is called micro propagation.”
“Regeneration of whole plant through tissue culture is popularly called micro Propagation.”
Micro Propagation can be achieved in a short time and space. Thus, it is possible to produce plants in large numbers starting from a single individual. Use of tissue culture for microprogation was initiated by G.Morel (1960) in orchid.
