Axillary buds are located at the intersection of the leaf and stem of a plant. The axillary bud (or lateral bud ) is an embryonic or organogenic shoot located in the axil of a leaf . Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots ( flowers ).
axillary, when located in the axil of a leaf (lateral is the equivalent but some adventitious buds may be lateral too); adventitious , when located elsewhere, for example on the trunk or roots (some adventitious buds may be former axillary ones that are reduced and hidden under the bark, while other adventitious buds are completely new formed ...
The leaves are alternate with two lateral veins beginning from the base, prominent and parallel to the midrib, crenate to crenate-serrate, or petiolate. The spikes are axillary or terminal, or both. The bracts are leaf-like. There are no petals. The flowers are pistillate with 3–5 sepals and a 3-locular ovary.
Other flowers then grow from lateral buds. Indeterminate and determinate inflorescences are sometimes referred to as open and closed inflorescences respectively. The indeterminate patterning of flowers is derived from determinate flowers. It is suggested that indeterminate flowers have a common mechanism that prevents terminal flower growth.
Lateral shoots/branches are often numerous on larger vegetation such as certain trees or bushes. A lateral shoot , commonly known as a branch , is a part of a plant's shoot system that develops from axillary buds on the stem's surface, extending laterally from the plant's stem .
Flower bud – Lateral – Latent bud – an axillary bud whose development is inhibited, sometimes for many years, due to the influence of apical and other buds. Also known as a dormant bud. Leaf bud – a bud that produces a leafy shoot. Mixed – buds that have both embryonic flowers and leaves. Naked – Pseudoterminal –
The inflorescence (flower) is lateral, axillary and borne from upper portion of stems. It is one-flowered (per stem), sometimes four or five flowers open simultaneously in succession per stem. The floral bracts are less than 1/8 the length of pedicel (stalk of a flower) and brownish in colour. The flowers are up to 1 cm in diameter and usually ...
They may develop on roots or leaves, or on shoots as a new growth. Shoot apical meristems produce one or more axillary or lateral buds at each node. When stems produce considerable secondary growth, the axillary buds may be destroyed. Adventitious buds may then develop on stems with secondary growth.
