What is the meaning of bolting?

Options

  1. AInternode elongation just after flowering
  2. BInternode elongation just prior to flowering
  3. CRemoval of dicot weeds
  4. DTo induce parthenocarpy

Correct answer

B. Internode elongation just prior to flowering

Step-by-step solution

One of the important hormones as growth regulator in plants is the gibberellins. It is a type of promotory hormones. One of the effects of this hormone is the increase in the axis of the stem. This property utilized by a horticulturist in inducing flowering by 'bolting'. In bolting, using the gibberellin hormone the flowering stem is developed by internode elongation before flowering.
