Question

Which hormones can replace vernalisation

Answer 1

Gibberellins affect several reproductive processes in plants. They stimulate flowering, particularly in long-day plants. In addition, gibberellins substitute for the low temperature that biennials require before they begin flowering (vernalisation). If gibberellins are applied to biennials during their first year of growth, flowering occurs without exposure to a period of low temperature. Gibberellins, like auxin, also affect fruit development. Agriculturalists apply gibberellins to several varieties of grapes to produce larger fruits.
