Artificial vegetative propagation -
Taking cuttings: a section of stem is cut between leaf joints, then treated with plant growth hormones to encourage root groth and is then planted. The cutting is then genetically identicle to the original plant.
Grafting - shoot section from woody plant is joined to an already growing a root and stem(root stock). The graft grows and is genetically identicle to parent plant but root stock is genetically different.
Artificial propogation using tissue culture: Large sclae cloning:
Taking cutting and grafting cannot produce large numbers of clones plants. Plant tissue culture however can, and can produce large numbers of daughter plants from a small amount of plant material.
Tissue culture can produce new plants very quickly, which are known disease free.
