Class 11 NEET Biology Plant Growth and Development

(c) : Gibberellins play a role in the elongation of internodes in 'rosette' plants. Before reproductive stage there is too much elongation of internodes but there is less leaf formation. An elongated internode without leaves in called a "bolt" like structure and the process is called "bolting" flowering takes place after bolting.
Gibberellins induce cell division and cell elongation, when bolting takes place.
