Phytohormones

What are Phytohormones?

Phytohormones are a class of plant growth regulators that play a crucial role in plant development and growth. They are produced by plants and can be applied exogenously to promote or inhibit specific physiological processes. Phytohormones can be classified into several types, including:

• Auxins: Auxins are involved in cell elongation, cell division, and root growth. They are commonly used to promote root development and increase crop yields.
• Gibberellins: Gibberellins are involved in seed germination, stem elongation, and leaf expansion. They are commonly used to promote seed germination and increase crop yields.
• Cytokinins: Cytokinins are involved in cell division, cell growth, and root development. They are commonly used to promote root development and increase crop yields.
• Ethylene: Ethylene is involved in fruit ripening, senescence, and stress responses. It is commonly used to promote fruit ripening and improve fruit quality.
• Abscisic acid: Abscisic acid is involved in stomatal closure, stress responses, and seed dormancy. It is commonly used to promote drought tolerance and improve crop yields.
