Nature of Vernalization Stimulus

Nature of Vernalization Stimulus – Vernalin or Gibberellin Many attempts were made to isolate vernalin but all failed. However, Anton Lang in 1957 showed that application of gibberellins to certain vernalization requiring biennials like henbane induce flowering in them without cold temperature treatment. Purvis in 1961 induced winter annuals to flowers induced by treating their seeds with gibberellins. It was ...

Vernalization Vernalization is a process that promotes flowering by cold temperature treatment given to a seed that has imbibed water or to a growing a plant. Like photoperiodism, vernalization is also an inductive effect leading to flowering sometime after the cold temperature treatment. If cold temperature treatment is not provided to cold requiring plants they may either show delayed flowering ...
