Plant physiology

A long cold spell makes a plant competent to flower

In plant physiology, vernalization is the acquisition or acceleration of the ability to flower brought about by an extended exposure to cold, which lets many winter annuals and biennials sense that winter has passed before they bolt and flower in spring. Chouard's 1960 Vernalization and its relations to dormancy set out the phenomenon: a prolonged chilling perceived largely at the shoot apex that is remembered through later growth, and he distinguished it from dormancy and from daylength responses. The referent is a cold-driven switch in flowering competence, characterised by the duration and temperature of chilling required, and in modern terms it works by the gradual, cold-mediated silencing of floral-repressor genes.[1]

Unit
The length and temperature of cold exposure needed to make a plant competent to flower
Recovery means
Not applicable
Measured by
