Definition - What does Adventitious Bud mean?
In botany, adventitious buds refers to the roots or buds that emerge in areas where they do not usually develop. They usually arise from latent or dormant buds located in the leaf axils of younger stems and will remain indefinitely until they are removed.
In older plants, adventitious buds tend to develop from the plant’s meristem or secondary tissues, which normally arise from mature organs.
In most cases, adventitious buds grow from the stems and leaves, but they can occasionally form new plants that sprout directly from the roots.
MaximumYield explains Adventitious Bud
According to botanists, adventitious buds can emerge at any moment in a plant’s life, regardless of its age. In some cases, these buds have been known to boost the plant’s growth and overall health if the apical meristem is damaged.
Tree stumps have been known to produce a whole new tree from adventitious budding. Additionally, dormant buds can emerge if the plant’s stem receives any kind of injury. This often happens from the plant’s upper stem after pruning.
As far as mature tree trunks are concerned, they can produce adventitious buds if a usually-shaded trunk is suddenly exposed to sudden sunlight on a daily basis.
The word adventitious comes from the Latin root advenire, which means "to come to". In English, the meanings also translate to "accidental/casual occurrence", "arising from without; supervenient, accidental, casual".
