Question

Which of the following hormones can replace vernalization ?

Options

A.Auxin
B.Cytokinin
C.Gibberellins
D.Etrhylene

Solution

Vernalization refers to the application of low temperature to moistened seeds and young plants, causing shortening of vegetative phas and initiation of reproductive phase. A Lang and coworkers (1966) postulated that, low temperature induces synthesis of vernalin that causes flowering, though Chailakhyan (1968) stated that under long-day conditions vernalin turn into gibberellin and thus, in some plants, the requirement for vernalization is overcome by gibberellins.
