Therefore, the solution that you are looking for is cytokinin.
Which plant hormone promotes the growth of the plant?
One example of a hormone produced by a plant that encourages the development of the plant is called auxin. Auxins encourage the growth of longer stems but suppress the development of lateral buds (maintains apical dominance).
What is the function of auxin in plants?
One example of a hormone produced by a plant that encourages the development of the plant is called auxin. Auxins encourage the growth of longer stems but suppress the development of lateral buds (maintains apical dominance). They are formed in the buds, stem, and the very tips of the roots.
What stimulates cytokinesis in plant cells?
2. Cytokinins It is responsible for stimulating cytokinesis, which is created by plants in their roots and then transferred to their various organs. a. Cytokinins and auxin compete with one another during cell division and cytokinesis. Auxin released from the terminal bud enables the shoot to grow longer.
What promotes growth of lateral buds?
A treatment with gibberellin encourages the proliferation of lateral buds.
Does cytokinin promote lateral bud growth?
Based on these findings, it appears that both cytokinins and ethylene play important parts in the process of naturally occurring lateral bud initiation, and that the action of cytokinins includes two distinct phases of the process.
How do lateral buds grow?
Lateral buds develop along the sides of a stalk and are the source of the development that occurs laterally, which gives a plant its bushy appearance. These buds will remain dormant either until the shoot has reached a length that makes the hormones released by the terminal bud less influential or until the terminal bud is removed from the plant; at that point, they will begin their growth.
How does auxin inhibit lateral bud growth?
A growing stem is a powerful sink for sugars, and sugar is required for shoot branching, so the indirect theory of apical dominance might now be explained as auxin-induced stem growth inhibits bud outgrowth by diverting sugars away from buds. This would be consistent with the fact that a growing stem is a powerful sink for sugars.
What is the role of cytokinin?
During the proliferation stage of leaf cell development, cytokinins encourage cell division and boost cell growth. During the expansion stage of leaf cell development, cytokinins have the opposite effect. During the process of leaf senescence, cytokinins prevent the buildup of sugar, speed up the synthesis of chlorophyll, and extend the leaf’s duration of photosynthetic activity.
Does auxin promote shoot growth?
Auxin is responsible for the stimulation of cell elongation in the shoots, and as a result, high amounts of auxin encourage growth (cells become larger)
What is lateral bud development?
The SAM is placed below the lateral bud primordium, which is the starting point from which the lateral bud grows.Through the process of repression of auxin, the shoot tip that emerges from the SAM suppresses the development of the lateral bud.The release of cytokinin causes the lateral bud to begin to extend after the shoot is severed.This process is mediated by the lengthening of the lateral bud.
Does auxin promote root growth?
A potent growth hormone that is naturally generated by plants, auxins are called auxins.They encourage cell division as well as the growth of stems and roots, and may be found in the tips of shoots and roots.They are also able to have a significant impact on the orientation of the plant by encouraging cell proliferation on one side of the plant in response to the effects of gravity and sunlight.
What are the hormones responsible for plant growth promoting axillary bud growth and apical dominance?
Auxins encourage the growth of longer stems but suppress the development of lateral buds (maintains apical dominance). They are formed in the buds, stem, and the very tips of the roots. Example: Indole Acetic Acid (IA). Auxin is a plant hormone that is generated at the very tip of the stem and is responsible for the elongation of plant cells.
What is stress hormone in plant?
The Hormone That Causes Stress The ability of plants to withstand heat stress is increased by the presence of abscisic acid. Abscisic acid, often known as ABA, is a phytohormone that is essential for plant development and governs the ways in which plants react to stress.
Which of the following inhibits the growth of lateral axillary buds?
It has been known for a long time that auxin may hinder the growth of axillary buds, but cytokinins can increase the formation of axillary buds.
Does auxin inhibit lateral buds?
When administered to the stem stump of the majority of the species examined at concentrations of 10 and/or 10 percent auxin in aqueous solution, auxin produced a considerable reduction in the amount of lateral bud outgrowth that occurred after the decapitation of the plant.
What are auxins and cytokinins?
Auxin and cytokinin are two important hormones that play a role in regulating the growth and development of plants.The levels of hormones in cells and tissues are carefully regulated throughout development, on a 24-hour basis, and in reaction to environmental factors.This is because hormones are active at very low concentrations and they are responsible for the regulation of dynamic processes.
How does auxin affect axillary buds?
When a plant has strong apical dominance, the shoot apex provides the major stem with auxin and suppresses the expansion of axillary buds. Both of these processes take place at the same time. Because the saturated polar auxin flow in the major stem does not become a sink for the auxin flux coming from the axillary buds, the PIN auxin efflux carriers in the buds have not become polarized.
