Bolting is induced by plant hormones of the gibberellin family, and can occur as a result of several factors, including changes in day length, the prevalence of high temperatures at particular stages in a plant’s growth cycle, and the existence of stresses such as insufficient water or minerals.

Which of the following is bolting hormone?
Plant-hormone gibberellins can artificially cause bolting. These plant hormone gibberellins are naturally found in the plants but can also be exogenously produced. The height of intermodal regions present in the stem is increased by these gibberellins.
What does bolting look like?
The signs are easy to identify: Sudden, upward growth—usually of a singular, woody stalk with few leaves. Production of flowers, followed by that of seeds. Slowed production of edible, vegetative growth.
