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 . Once formed, a ...
Cytokinin moves from the roots into the shoots, eventually signaling lateral bud growth. Simple experiments support this theory. When the apical bud is removed, the axillary buds are uninhibited, lateral growth increases, and plants become bushier. Applying auxin to the cut stem again inhibits lateral dominance. [2]
A terminal bud occurs on the end of a stem and lateral buds are found on the side. A head of cabbage (see Brassica) is an exceptionally large terminal bud, while Brussels sprouts are large lateral buds. [citation needed] Since buds are formed in the axils of leaves, their distribution on the stem is the same as that of leaves. There are ...
The shoot tip rising from the SAM inhibits the growth of the lateral bud by repressing auxin. When the shoot is cut off, the lateral bud begins to lengthen which is mediated by a release of cytokinin. Once the apical dominance has been lifted from the plant, elongation and lateral growth is promoted and the lateral buds grow into new branches.
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 –
This is a process known as vegetative reproduction and is used by farmers and gardeners to propagate certain plants. This also allows for lateral spread of grasses like bamboo and bunch grasses. Examples of plants that are propagated this way include hops, asparagus, ginger, irises, lily of the valley, cannas, and sympodial orchids.
The offspring or new tubers are attached to a parent tuber or form at the end of a hypogeogenous (initiated below ground) rhizome. In the autumn the plant dies, except for the new offspring tubers, which have one dominant bud that in spring regrows a new shoot producing stems and leaves; in summer the tubers decay and new tubers begin to grow.
