Bud

Bud [ Botany ]

Dictionary of botanic terminology - index of names

A bud is a growing point enclosed by closely overlaid rudimentary leaves. Buds are immature shoot and may contain developing leaf, stem or flowers.

Buds that develop in the tip of a stem or branch are called apical or terminal bud, while the buds that originate in the
axil of a leaf are called axillary buds.

A bud is small swelling or protuberance on a stem or branch. It correspond to a region of meristematic tissue containing a rudimentary or undeveloped shoot, leaf or flower, often enclosed in protective scales generally in a compact cone-shaped structure and normally occurs in the axil of a leaf or at the tip of the stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot, leaf or flower immediately.

Bulbs and bulbils are forms of leaf buds.

Buds appearing in an unusual place are called adventitious buds.

In bud = having new buds that have not yet opened
Budding = Stage in the Growth Cycle in which the leaves and/or flowers begin to sprout

Bud Parts:

Bud Primordium: Meristematic tissue that gives rise to a lateral bud or shoot.
Flower Primordium: Meristematic tissue that gives rise to a flower.
Leaf Primordium: Meristematic tissue that gives rise to a leaf.
Promeristem: Apical growing or meristematic tissue that gives rise to other bud parts.
Scale: Protective leaf on outside of bud.

Bud Structural Types (Classification based on composition and cover)

Flower bud: An unexpanded blossom or a growing tip surrounded by its immature perianth segments. Contains flower primordia; will give rise to one or more flower.
Leaf bud or gemma: Contains leaf and stem primordia; will give rise to branch with leaves.
Mixed bud: Contains flower, leaf, and stem primordia; will give rise to branch with leaves and flower(s).
Naked bud: Shoot and/or flower primordia not surrounded by scales.
Protected bud: Shoot and/or flower primordia surrounded by scales.

Bud Types (Classification based on position and arrangement)

Accessory Buds: Lateral to or above axillary buds.
- Collateral Buds: Lateral to axillary buds.
- Superposed buds: Above axillary buds.
Axillary or Lateral buds: In axils of leaves or leaf scars.
"Infra"-petiolar or "Sub"-petiolar: axillary buds surrounded by the base of the petiole.
Pseudoterminal: Bud appearing apical but is lateral near apex, developing with death or non-development of terminal bud.
Terminal bud: At apex or end of stem.
