Bolting is a phenomenon in plants where there is sudden shoot elongation followed by flowering. It can be induced artificially by treating the plant with the hormone gibberellin, which is naturally found in plants but can also be produced externally. Rosette plants exhibit excessive intermodal growth when treated with gibberellins, leading to sudden elongation of the stem and bolting.

In summary, bolting can be induced artificially by treating the plant with gibberellin, which leads to sudden shoot elongation followed by flowering.
