Plant hormones are chemical compounds present in very low concentration in plants. They are derivatives of indole (auxins), terpenes (Gibberellins), adenine (Cytokinins), carotenoids (Abscisic acid) and gases (Ethylene).
Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, [1] the regulation of organ size, pathogen defense, [2] [3] stress tolerance [4] [5] and reproductive development.

Jan 28, 2020 · Plant hormones are natural substances which control many aspects of plant development. They control everything from the length between nodes on the branches to the programmed death, or senescence seen in many annual plants.
Jul 27, 2022 · Understand the role of the five major hormone groups in plant growth and development. Recognize that cells, tissues, and organs have unique competency to respond to specific hormones. Connect specific hormones to plant responses and how they are used in plant propagation.
Feb 14, 2024 · Plant hormones are a group of unrelated chemical substances that affect plant growth, development, and other physiological processes. Five major plant hormones are traditionally described: auxins (particularly IAA), cytokinins, gibberellins (GAs), abscisic acid (ABA), and ethylene.
Plant hormones are signal molecules that are synthesized de novo in plants. They are conserved in the plant kingdom and regulate diverse processes in plant growth and development and in acclimation responses to abiotic and biotic stresses.
Apr 17, 2009 · The plant hormones are a structurally unrelated collection of small molecules derived from various essential metabolic pathways. These compounds are important regulators...
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
May 5, 2022 · Plant hormones are signalling compounds that regulate crucial aspects of growth, development and environmental stress responses. Abiotic stresses, such as drought,...
