WebRegulation of flowering is one of the most important processes of plants since it is closely related to the success of reproduction. Flowering time is controlled by a number of environmental factors such as day length, temperature, and water supply. Among them, the photoperiod is a key regulator of flowering and has been studied for many years ... WebTherefore, they adapt their physiology and behavior, including flowering, growth, migration, hibernation, and molting. Garner & Allard demonstrate that the photoperiod is the dominant cue driving seasonal responses by using soy and tobacco plants; accordingly, organisms’ responses to changing daylength are referred to as photoperiodism.
