The axillary buds begin developing when they are exposed to less auxin, for example if the plant naturally has weak apical dominance, if apical dominance is broken by removing the terminal bud, or if the terminal bud has grown far enough away for the auxin to have less of an effect.
These are hard, woody, pointed structures meant for protection. They are provided with vascular tissue, [12] which may develop from the axillary bud or terminal buds. [13] They control transpiration by reducing the vegetative growth. In Bougainvillea, Punica granatum, and Duranta, the axillary bud develop into thorns.
The term is usable as a synonym of resting, but is better employed for buds waiting undeveloped for years, for example epicormic buds; pseudoterminal, for an axillary bud taking over the function of a terminal bud (characteristic of species whose growth is sympodial: terminal bud dies and is replaced by the closer axillary bud, for examples ...
The apical bud produces a plant hormone, auxin , that inhibits growth of the lateral buds further down on the stem towards the axillary bud. Auxin is predominantly produced in the growing shoot apex and is transported throughout the plant via the phloem and diffuses into lateral buds which prevents elongation. [2]
Arranged on a conical surface (like a snail shell); used to describe inflorescence s in which the bud s are arranged in an almost helical manner on the outside of a long, tapering, conical rachis. bract A modified leaf associated with a flower or inflorescence and differing in shape, size, or color from other leaves (and without an axillary bud ...
Accessory bud – an embryonic shoot occurring above or to the side of an axillary bud; also known as supernumerary bud. Adventitious bud – a bud that arises at a point on the plant other than at the stem apex or a leaf axil. Axillary – an embryonic shoot which lies at the junction of the stem and petiole of a plant. Dormant – see "Latent ...
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. Importance to photosynthesis
The nodes are the eyes and each has a leaf scar. The nodes or eyes are arranged around the tuber in a spiral fashion beginning on the end opposite the attachment point to the stolon. The terminal bud is produced at the farthest point away from the stolon attachment and tubers, and thus show the same apical dominance as a normal stem.
