Periodicity in plants [growth]

Growth processes in plants are not continuous, but during the year some plant growth periodicity is observed.

In humid continental climate, this periodicity is closely related to unfavorable conditions of winter. In the fall day severely shortens and gradually decreases the temperature. All these changes in the natural environment have consequences for the perennial. It adapts to them, prepares for winter. At this time undergoes the accumulating of nutrients for the winter, and also one their forms transform into another. For example, starch transforms into sugar and oil. The plant sheds its leaves and abruptly reduces the intensity of their metabolism. Plant is like pauses for the winter. Taken from http://worldofschool.org

Complete suspension of vital functions does not occur in the winter. Although breathing undergoes significantly slower. According to N. A. Maksimov, the breath of a number of wood species in winter decreases down to 1/200 of the normal breathing during the growing season.
