terminal bud

The presence of this tip-scar indicates that the terminal bud is absent.

A terminal bud is one situated at the end of a twig, where it is ready to continue the growth of the twig the following spring.

When the terminal bud is thus prevented from continuing its growth, the nearest axillary buds are developed.

The axillary buds seldom grow unless the terminal bud is interrupted.

On the cessation of growth in length, a terminal bud is formed and the tree begins to go into rest.
