bolting

an unusual lengthening of plant stems, due to elongation of cells, which can be induced by plant hormones called GIBBERELLINS producing a stem with long INTERNODES. Bolting can occur naturally, as when biennials such as cabbage and sugar beet produce elongated flower stalks in their first year rather than flowering in the second year. The problem arises when such plants are subjected to winter conditions in their first year (usually having been planted too early in the spring) which induces growth typical of the second year.
