Question
Induction of flowering by low temperature treatment is
vernalization
cryobiology
photoperiodism
prunning
Solution
A.
vernalization
Vernalization is chilling or cold treatment of the young plants in order to induce flowering. It is a process for shortening the juvenile or vegetative phase of the plants in order to fasten the flowering process. Common examples includes winter rye, winter wheat, winter barley, pea etc.
Cryobiology is the study of life at low temperature, ie, at liquid nitrogen and preservation of organisms by chemical methods.
Photoperiodism is the effect of photoperiods or daily duration of light hours on the growth and development of flowering in plants.
