Plant Hormones: Definition, Types, Function, Auxin - BYJU'S
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 - The Definitive Guide | Biology Dictionary
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.
Plant hormone - Wikipedia
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. [6]
Plant Hormones – Types, Functions & Uses - Science Facts
Feb 2, 2023 · Plant hormones or phytohormones are chemical compounds found in low quantities in plants and also in algae. They control their overall growth and development, reproductive processes, environmental responses, and even death. Thus, they are also called plant growth regulators (PGRs). Sometimes PGRs are also synthesized artificially.

Apr 5, 2024 · Plant hormones also known as Phytohormones, are essential chemical messengers that orchestrate a myriad of vital processes in plants. They control growth by influencing cell elongation, division, and differentiation through hormones.
11: Plant Hormones - Biology LibreTexts
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.

Hormone - Plant Growth, Photosynthesis, Reproduction | Britannica
Nov 30, 2024 · Hormone - Plant Growth, Photosynthesis, Reproduction: Growth in plants is regulated by a variety of plant hormones, including auxins, gibberellins, cytokinins, and growth inhibitors, primarily abscisic acid and ethylene.
How hormones and growth regulators affect your plants
Jul 9, 2024 · There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances. Auxin causes several responses in plants: Bending toward a light source (phototropism).
