Does cytokinin promote apical dominance?
Apical dominance is suppressed under the effect of high cytokinin concentration and permits the development of axillary buds. If a number of side shoots or axillary shoots have been formed on the shoot tip then their inoculation may be done on the fresh medium containing cytokinin.
What is the difference between cytokinin and kinetin?
Cytokinins are substances close to purine bases (substituted adenins). It is a family of phytohormones essential for the development of the plant as well as auxin, which acts as hormones in plants. Kinetin is a cytokinin-like synthetic compound that regulates cell growth in plants.
Is kinetin a cytokinin?
Overview. Kinetin is a cytokinin. Cytokinins are compounds that stimulate plants to grow. Kinetin occurs naturally in humans and is sometimes used to make medicine.
Which hormone is associated with kinetin and zeatin?
cytokinins
There are two types of cytokinins: adenine-type cytokinins represented by kinetin, zeatin, and 6-benzylaminopurine, and phenylurea-type cytokinins like diphenylurea and thidiazuron (TDZ). Most adenine-type cytokinins are synthesized in roots.
What is apical dominance which hormone promote and inhibit apical dominance?
Apical dominance is a phenomenon wherby, the inhibition of the growth of lateral buds occurs due to the terminal bud of a shoot. It is caused by the production of IAA (auxin) in abundance by the apical bud. This auxin is transported basipetally from the apical bud. The auxin causes the lateral buds to remain dormant.
What do cytokinins promote?
Cytokinins are essential plant hormones. By stimulating cell division, they regulate shoot meristem size, leaf primordia number, and leaf and shoot growth. They can stimulate both the differentiation and the outgrowth of axillary buds. The cytokinins can mediate axillary bud release from apical dominance.
Which is responsible for apical dominance?
Auxins are responsible for shoot apical dominance seen in the central shoot. The growth of axillary buds into shoots is inhibited by auxin.
What is the role of kinetin?
Kinetin is a cytokinin which are plant hormones promotes cell division and plant growth. It was shown to naturally exist in DNA of organisms including humans and various plants. While kinetin is used in tissue cultures to produce new plants, it is also found in cosmetic products as an anti-aging agents.
What is kinetin soluble?
Slightly soluble in cold water, methanol, ethanol. Freely soluble in dilute aqueous hydrochloric acid or sodium hydroxide.
What does kinetin mean?
Definition of kinetin : a cytokinin C10H9N5O used especially to stimulate cell division in plant tissue culture.
What is apical dominance a common effect of?
Apical dominance occurs when the shoot apex inhibits the growth of lateral buds so that the plant may grow vertically. It is important for the plant to devote energy to growing upward so that it can get more light to undergo photosynthesis.
How does cytokinin influence the growth and development of plants?
Cytokinins are essential plant hormones. By stimulating cell division, they regulate shoot meristem size, leaf primordia number, and leaf and shoot growth. They can stimulate both the differentiation and the outgrowth of axillary buds.
