In most higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called as apical dominance. Apical dominance is thought to be due to production of auxins in the stem tips.

An apical bud is the primary growing bud located at the tip of the stem in a plant. Apical buds make auxin that is distributed throughout the plant via the phloem. Auxin prevents the growth of lateral buds. This phenomenon is called apical dominance.

Apical bud dominates over the growth of lateral buds, this phenomenon is called. View Solution. Q4. The ...

Eye of the potato is the axillary bud. The axillary bud is an embryonic shoot which lies at the junction of the stem and petiole of a plant. As the apical meristem grows and forms leaves, it leaves behind a region of meristematic cells at the node between the stem and the leaf.

Apical bud is the bud located at the top of the plant. Axil is the angle between the upper side of the stem and a leaf, branch, or petiole. The axillary bud (or lateral bud) is an embryonic shoot located in the axil of a leaf. Vegetative bud is a leaf bud or the bud that contains embryonic leaf. Flower bud is a bud that develops into a flower.

When there is the presence of the apical bud in a plant, there is suppression of the growth of the lateral buds and this phenomenon is called as apical dominance. The hormone auxin produced at these tips causes the growth and elongation of only …

Apical dominance is a phenomenon in which central stem is dominant and lateral stems are suppressed. It is due to plant hormones produced in the tip of the shoot. Auxin hormone is responsible for apical dominance. When apical bud is removed, there is growth of lateral bud. This results in formation of lateral branching. This makes plant bushy.

When the apical bud is removed, the lateral buds sprout. Apical bud inhibits the growth of lateral buds by releasing auxins. When a plant is decapitated i.e., its apical bud is removed then the lateral buds sprout, resulting in dense bushy growth. This phenomenon is widely used in the tea plucking and hedge making.

Young developing leaves also produce auxins and it has been shown that auxins from this source may inhibit lateral bud growth. When the apical bud is removed, the lateral bud sprout. However, if a paste of auxin is painted on the cut end of the decapitated shoot, the lateral buds remain inhibited, as if the apical bud is present.

Apical dominance is a phenomenon in which central stem is dominant and growth of lateral buds is inhibited. It is due to plant hormones produced in the tip of the shoot. Auxin hormone is responsible for apical dominance and cytokinin hormone is responsible for …
