Plants which is dependent on a very low temperature for its flowering is called "vernalisation".

★ VERNALISATION:-
→ This is the phenomenon in which some plants are dependent quantitatively or qualitatively on exposure to low temperature for flowering.
→ Examples for vernalisation are as follows:
- Some food plants
- Wheat
- Barley
- Rey
→ Rye have two kinds of varieties:
o Spring varieties: These are normally planted in the spring and come to flower and produce grain before the end of the growing season.
o Winter varieties: Winter varieties if planted in spring would normally fail to flower or produce mature grain within a span of a flowering season. Hence, they are planted in autumn.
→ They germinate, and over winter come out as small seedlings, resume growth in the spring, and are harvested usually around mid-summer.
