Apical Bud vs. Axillary Bud — What's the Difference?
By Tayyaba Rehman — Published on January 1, 2024
Apical Bud is the main growth point located at the tip of a plant stem. Axillary Bud lies in the leaf axils, often giving rise to branches or flowers.

Key Differences
Apical Bud refers to the dominant bud located at the top or apex of a plant stem. This bud controls the growth direction and determines the overall shape and height of the plant. In contrast, Axillary Bud is found at the junction where the leaf meets the stem, known as the leaf axil.
Apical Bud plays a key role in the vertical growth of plants. It releases a hormone that suppresses the growth of Axillary Buds below it, a phenomenon known as apical dominance. On the other hand, Axillary Buds often remain dormant unless the Apical Bud is removed or its dominance is reduced.
Both Apical and Axillary Buds have the potential to develop into stems, leaves, or flowers. While the Apical Bud ensures the plant grows upwards towards the light, Axillary Buds provide opportunities for lateral growth or branching. When the Apical Bud is pruned or damaged, it can lead to the activation of Axillary Buds.
In agriculture and horticulture, understanding the behavior of both Apical Bud and Axillary Bud is crucial. For instance, when gardeners want to encourage bushier growth, they might remove the Apical Bud. This act reduces apical dominance, allowing Axillary Buds to grow and produce new branches.

Common Curiosities
Why is the Apical Bud sometimes called the terminal bud?
Because it's located at the terminal or tip of the stem.
Do Axillary Buds always grow into branches?
No, Axillary Buds can develop into branches, leaves, or flowers.
What happens if you remove the Apical Bud?
Removing the Apical Bud often stimulates the growth of Axillary Buds, leading to bushier plants.
Can Axillary Buds become dominant if the Apical Bud is damaged?
Yes, if the Apical Bud is damaged or removed, an Axillary Bud can take over and become the new dominant growth point.
Why are Axillary Buds important in gardening?
Axillary Buds provide opportunities for lateral growth, branching, and flowering, which can be managed through pruning.
What is the main function of the Apical Bud?
The Apical Bud directs upward growth and determines a plant's overall shape and height.
Where is the Axillary Bud located?
The Axillary Bud is found where the leaf meets the stem, known as the leaf axil.
Why do some plants have dormant Axillary Buds?
Apical dominance, exerted by the Apical Bud, often suppresses the growth of Axillary Buds.
Can both Apical Bud and Axillary Bud produce flowers?
Yes, both can give rise to flowers depending on the plant species and conditions.
How can I encourage more Axillary Bud growth?
By pruning or reducing the influence of the Apical Bud, Axillary Buds can be encouraged to grow.
What role does the Apical Bud play in tree growth?
The Apical Bud ensures trees grow tall and straight by promoting vertical growth.
Are the hormones from the Apical Bud responsible for suppressing Axillary Bud growth?
Yes, the Apical Bud releases hormones that can suppress the growth of Axillary Buds.
Is the Apical Bud always larger than the Axillary Bud?
Not always, but the Apical Bud is often more prominent due to its dominant role in growth.
Do all plants have both Apical and Axillary Buds?
Most vascular plants have both, but their prominence and behavior can vary depending on the species.
