Question

The spring wood and autumn are arranged alternatively. why?

Answer 1

The activity of the cambium ring is influenced by the climatic charges. Reactivation of the cambium takes place during spring season. The cambium becomes more active during this season and forms plenty of xylem vessels with wider cavities known as spring wood. It is also known as early wood. In winter, however, the cambial activity slows down and gives rise to narrower xylem elements. The wood thus formed in winter is called autumn wood. It is also known as late wood.
