Terminal bud

/ˈtɜrmɪnəl bʌd/ noun

Definition

The growing point located at the tip of a stem or branch that controls primary growth and vertical elongation. It typically suppresses the growth of axillary buds through apical dominance.

Etymology

From Latin 'terminus' meaning 'end' or 'boundary' combined with 'bud.' The term reflects its position at the terminal end of growing shoots and was established in botanical terminology by the 19th century.

Kelly Says

The terminal bud is like the plant's CEO - it's in charge and keeps all the lower buds in line! This 'apical dominance' is why Christmas trees have that perfect triangular shape naturally, and why pinching the top makes plants bushier.
