Plant hormones include ethylene, gibberellins, cytokinins, absciscic acid, and auxins.
What are the major types of plant hormones?
Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides.
How many hormones are in plants?
There are five general classes of hormones: auxins, cytokinins, gibberellins, ethylene, and abscisic acid.
What are the major plant hormones and what do they do?
There are five major types of plant hormones: auxins, cytokinins, gibberellins, ethylene and abscisic acid. Each hormone has a distinct job and for oilseed, pulse and cereal crops, auxins and cytokinins can greatly improve plant vigor, promote growth of roots and shoots and reduce stress.
What is the most important plant hormone?
Auxins have a cardinal role in coordination of many growth and behavioral processes in the plant’s life cycle and are essential for plant body development.
Which is the plant stress hormone?
Abscisic acid (ABA), termed stress hormone, plays an important role in plant leaves abscission and abiotic stresses tolerance .
What are the five classes of plant hormones?
Initial research into plant hormones identified five major classes: abscisic acid, auxins, cytokinins, ethylene, and gibberellins.
How do cytokinins work?
Cytokinins are synthesized in the roots and are usually derived from adenine. They move upward in the xylem (woody tissue) and pass into the leaves and fruits, where they are required for normal growth and cell differentiation. The structures of plant hormones.
What is the role of auxin hormone?
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. … This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
