In modern day agriculture, along with pesticides and fertilizers, several compounds classified as plant growth stimulants become exceedingly important for sustainable crop production.

Agricultural products in this category include diverse compounds that are applied to crops or soils towards improving growth, yield and quality of crops as well as tolerance towards environmental stresses.

Although these compounds influence plant growth and development throughout the entire crop life cycle, a summary of their main functions is supplied below.

Organic Acids
Alginic acid Present in seaweed extracts; assist in maintaining turgor pressure in plant cells.

Amino acids

Increase nutrient uptake by plants and improve overall soil structure and health.

Humic substances

Present in seaweed extracts; assist in maintaining turgor pressure in plant cells.

Salicylic acid

Induces flowering and defence responses to environmental stresses.
Hormones & Bio-stimulants

Auxins (IAA)

Promote cell elongation in the stems, root tips and apical buds of plants.

Cytokinins (CYT)

Promote plant growth and development including as embryogenesis, maintenance of root and shoot meristems and vascular development.

Gibberellins (GA)

Stimulate stem elongation, seed germination and flowering.

Abscisic acid (ABA)

Induces stomatal closure when soil water is insufficient, maintaining transpiration.

Ethylene (ET)

Promotes seed germination, formation of root hairs, crop senescence and fruit ripening.

Jasmonic acid (JA)

Promotes fruit ripening and tuber formation as well as defence responses to environmental stresses.

Brassinosteroids (BR)

Optimize crop growth and yield as well as defence responses to environmental stresses.

Polyamines (PA)

Stimulate root initiation, flower development and tuber formation.


Optimizes photosynthesis and therefore plant growth.


Antioxidants protecting crops against oxidative stresses.


Supports crop growth and production and increases plant pigment concentrations.
