Plant growth hormones, or phytohormones, can be utilized in agriculture to enhance crop development, improve yields, and manage growth patterns. For instance, auxins promote root development and can be used for tissue culture propagation, while gibberellins stimulate seed germination and fruit development. Cytokinins can delay leaf senescence and improve nutrient mobilization, while abscisic acid helps in stress responses. By applying these hormones strategically, farmers can optimize plant growth, increase productivity, and achieve better management of agricultural resources.

How synthetic plant hormones are effective as weedkillers?
Plant hormones don't kill weeds. They are used for killing pests like aphids which absorb the hormone present in the phloem of the plant. These hormones are toxic for them and they die after consuming them.
What is ga3?
GA3 is gibberellic acid, a plant hormone that is involved in various processes such as seed germination, stem elongation, and flowering. It is commonly used in agriculture to promote plant growth and development.
How do plant hormones benefit the plant?
Plant hormones such as auxin work well in weed killers. It seems that these chemicals are taken up more easily by plants with two cotyledons more easily than monocotyledon plants. the chemicals in the weed killer then change the growth patters of the plant. these new growth patters of the plant result n the production of another plant hormone ethylene. there is probably more behind how plant hormones work as plank killers. the truth is not really known about it. the hypothesis is that the chemicals in the weed killer stop production of chemicals that the plant needs for growth. by A.wilson
How are hormones used to help plants and animals grow better?
Hormones are chemical substances that regulate growth processes in plants and animals. In plants, hormones like auxins, gibberellins, and cytokinins control cell division, elongation, and differentiation, leading to better growth and development. In animals, hormones like growth hormone and thyroid hormone regulate growth and metabolism, promoting growth and development.
What are the 4 hormones used in horticulture?
The 4 hormones commonly used in horticulture are auxins, cytokinins, gibberellins, and abscisic acid. These hormones play key roles in plant growth and development, including cell division, shoot elongation, fruit development, and stress responses. By manipulating the levels of these hormones, horticulturists can control various aspects of plant growth and physiology.
What is cytokinins used for?
Cytokinins are plant hormones that promote cell division and regulate growth and development in plants. They are commonly used in agriculture to stimulate plant growth, improve crop yield, and delay aging processes in harvested plants. Additionally, cytokinins are used in tissue culture techniques to promote the growth of plant tissue in vitro.
How synthetic plant hormones are effective as weedkillers?
Plant hormones don't kill weeds. They are used for killing pests like aphids which absorb the hormone present in the phloem of the plant. These hormones are toxic for them and they die after consuming them.
A high concentration of auxins can inhibit plant growth Many of these compounds are used as what?
compare and contrast how the different concentration of auxins affects the plant growth?
What is tissue plant growth and how it is used?
Tissue plant growth refers to the propagation of plant tissues in a controlled environment to generate new plants. This technique is often used in agriculture and horticulture to produce genetically identical plants quickly and efficiently. It is utilized for purposes such as commercial plant propagation, breeding programs, disease-free plant production, and conservation of rare or endangered species.
What plant hormones might be used to enhance stem elongation and fruit growth?
Auxin is a plant hormone that can be used to enhance stem elongation, while gibberellins can stimulate fruit growth. These hormones can be applied through synthetic forms or through natural sources like foliar sprays to promote desired plant growth responses.
Why is growth hormones used in biology?
Growth hormones are mainly used in organisms, especially in livestock. An example would be that a farmer may want to increase the production of lean meat. So, he inserts growth hormones in cattle.
How is limestone important to agriculture?
Limestone is important to agriculture because it helps to improve soil quality. It is commonly used as a soil amendment to neutralize acidic soils, which can be detrimental to plant growth. Limestone also provides essential nutrients like calcium and magnesium to the soil, promoting healthy plant growth and improving crop yields.
What are thyroid hormones used for?
Thyroid hormones are necessary for regulating cell metabolism and growth.
What Minerals are used in agriculture?
Some common minerals used in agriculture include potassium, phosphorus, nitrogen, calcium, sulfur, and magnesium. These minerals are essential for plant growth and development, and are often added to soils through fertilizers to enhance crop productivity. Balancing the levels of these minerals in the soil is crucial for healthy plant growth.
What is ga3?
GA3 is gibberellic acid, a plant hormone that is involved in various processes such as seed germination, stem elongation, and flowering. It is commonly used in agriculture to promote plant growth and development.
What hormone or hormones can be used to assist plant growth?
Auxins which promote apical dominance, cell elongation and root growth and gibberilins which stimulate elongation growth.
Why are plant hormones used?
Growing cuttings. Cuttings develop much bigger root systems if they are dipped in hormone rooting powder or planted in rooting compound containing growth hormone - making it possible to clone plants quickly and cheaply. * Producing fruit without seeds. To do this, growth hormones are sprayed onto unpollinated flowers to make them grow fruit without fertilisation. * Ripening fruit. The plant hormone ethene is sprayed on fruits to make them ripen fast and all at the same time before harvesting. Bananas are harvested before they are ripe to reduce damage to them during transport, and then sprayed with ethene to ripen them. * Increasing the size of fruit. For example, grapes are sprayed with the hormone gibberellin to increase the size of the fruit. * Controlling weeds. Some synthetic weed killers which selectively kill unwanted plants contain growth substances that speed up the metabolism. As a result weeds like dock and dandelion grow so fast that their food and water supply cannot keep up, so they run out of energy and die
