There is a direct relationship between the diameter of a teak tree and the number of annual rings formed. As the tree grows older, more annual rings are added and the stem diameter increases gradually. These rings are produced by lateral meristematic activity. Therefore, counting annual rings helps estimate both the age and growth pattern of the tree.
