Biennials remain vegetative during the first season, and after being exposed to the cold temperatures of winter, they flower in spring. Majority of plants will not flower if they are not subjected to exposure and [...]

Definition of Vernalization: Many plants do not come to flower before they experience a low temperature. These plants remain vegetative during the warm season, receive low temperature during winter, grow further and then bear flowers and fruits. Requirement of [...]
Vernalization has multiple interactions with photoperiodism. Thus, a cold requirement for flowering appears to be associated with a specific photoperiod. The most well quoted instance is that of need for vernalization and LD which leads to flowering in late spring or early summer. However, a cold requirement may also be accompanied by a SD photoperiodic response. Vernalization is also known [...]
