How can plant hormones be used in agriculture?

Last Updated: 14th May, 2020

There are many types of plant hormones . They are used in agriculture and horticulture to have a specific effect. Their main function is to help plants grow and auxin stimulates plant cells to elongate . The apical meristem of a plant is one of the main places where auxin is produced.

Simply so, which hormone is responsible for plant growth?


Also, what is the importance of plant hormones? Plant hormones playa crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant.

Keeping this in view, how are cytokinins used in agriculture?

Cytokinins are one of the key phytohormones, which induce the cell division in plant roots and shoots. Cytokinins help in preventing the senescence of fruits, flowers, and leaves. They stop staining and yellowing of fruits and leaves. Cytokinins are commonly used in the agriculture industry to increase the yield.

Which hormone has inhibiting effects on growth of plants?

Plant hormones are chemicals that promote or inhibit growth in plants. There are 5 main types of plant hormones. Auxin, commonly abbreviated as IAA, gibberellins and cytokininins all promote plant growth. Abcisic acid and ethylene inhibit plant growth.

What are the 5 plant growth regulators?

Generally, there are five types of plant hormones namely, auxin, gibberellins (GAs), cytokinins, abscisic acid (ABA) and ethylene. In addition to these, there are more derivative compounds, both natural and synthetic, which also act as plant growth regulators.

What is the function of auxin?

Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation.

What is the function of gibberellin?

Function of Gibberellins
Gibberellins are growth hormones that stimulate cell elongation and cause plants to grow taller. Gibberellins also have a role in other plant processes, such as stem elongation, germination, flowering, and fruit ripening.

What stimulates plant growth?

We'll cover five major types of plant hormones: auxin, gibberellin, cytokinin, ethylene, and abscisic acid. These hormones can work together or independently to influence plant growth.

How do farmers use Auxins?

They are used in agriculture and horticulture to have a specific effect. Auxins were the first class of plant hormones to be discovered. Their main function is to help plants grow and auxin stimulates plant cells to elongate . The apical meristem of a plant is one of the main places where auxin is produced.

What is plant hormone and their function?

Plant hormones (phytohormones) are chemicals produced by plants that regulate their growth, development, reproductive processes, longevity, and even death. These small molecules are derived from secondary metabolism and are responsible for the adaptation of plants to environmental stimuli.

What are the functions of cytokinins?

Cytokinins are plant hormones that cause increased cell division by stimulating the process of mitosis. They are made naturally by plants but have been synthesized by humans. Increased mitosis results in plant growth and the formation of shoots and buds, as well as the development of fruits and seeds.

What are cytokinins give an example?

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. Cambium and other actively dividing tissues also synthesize cytokinins.

What is auxin and cytokinin?

auxin: a class of plant growth hormones that is responsible for elongation in phototropism and gravitropism and for other growth processes in the plant life cycle. cytokinin: any of a class of plant hormones involved in cell growth and division.

What is the main origin of cytokinin?

The first cytokinin was isolated from herring sperm in 1955 by Miller and his associates (Miller et al., 1955). This compound was named kinetin because of its ability to promote cytokinesis.

Draguta Digon


How does cytokinins affect plant growth?

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.

Nila Aramberri


How do plants respond to cytokinins?

They also modulate root elongation, lateral root number, nodule formation, and apical dominance in response to environmental stimuli. Thus, cytokinins are important signaling molecules for regulating growth and development throughout the life of the plant.

Abderrachid Roggeveen


What is the difference between auxins and cytokinins?

In the root meristem, auxin induces the meristematic cell division, whereas cytokinin promotes the cell to switch from the meristematic to differentiated state through inhibiting auxin signaling.

How do plant hormones work?

Plant cells produce hormones that affect even different regions of the cell producing the hormone. Hormones are transported within the plant by utilizing four types of movements. For localized movement, cytoplasmic streaming within cells and slow diffusion of ions and molecules between cells are utilized.
