Definition - What does Terminal Bud mean?
The terminal (apical) bud of a cannabis plant is the primary growing point located at the apex (tip) of the stem and is the dominant bud. The terminal bud can cause all the axillary (lateral) buds below it to remain dormant.
Terminal buds contain a special tissue called the apical meristem. The apical buds’ cells can divide indefinitely and produce all the differentiated tissue, including vegetative and reproductive organs.
Hydrolife explains Terminal Bud
The terminal bud is the main area of growth in most plants where its own growth exhibits apical dominance, inhibiting the growth of axillary buds. Around the terminal bud is a complex arrangement of nodes and internodes with maturing leaves.
The terminal bud is the end of the embryonic shoot that is undeveloped. Also known as the apical bud, the terminal bud on a stem releases a hormone that prevents axillary buds from growing. It causes the axillary buds to grow slowly, which then allows the plant to grow taller to reach more light.
When the apical bud is removed, the hormone signal stops and the axillary buds can grow more vigorously. In cannabis cultivation, removing the terminal bud is known as pinching, or pinching back and is done to create a fuller, bushier plant.
The apical buds occur at the end, or apex, of stems, and because of this location, they are also known as terminal buds. These axillary buds occur at a leaf node, which is where a leaf emerges from the stem of a stem.
