Budding Stages
Bud Development• Buds are formed the previous summer while the
tree is in its growing phase.
• The buds remain dormant through the fall and winter.
• In the spring, the buds start to grow again and burst open, cracking open the protective scales that cover them.
• Some trees make flowers first while others make leaves first, but they both come from buds.
Basic Parts of a Twig
• terminal bud — a bud that is at the tip of a stem or branch
• bud scale — a small modified leaf on the outside of a bud
• lateral bud — a bud that is situated along the sides of a branch and not at the tip
• leaf scar — the scar left on a twig when a leaf falls
• pith — central, usually soft portion of a twig
