Branches of botany

Last updated November 15, 2025

Botany is a natural science concerned with the study of plants. The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, applied topics which study the ways in which plants may be used for economic benefit in horticulture, core topics which associate with agriculture and forestry concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity, and organismic topics which focus on plant groups such as algae, mosses or flowering plants. ^[1]

Applied topics

Agronomy – Application of plant science to crop production
Arboriculture – Culture and propagation of trees
Astrobotany - The study of plants in space
Biotechnology – Use of plants to synthesize products
Dendrology – Study of woody plants, shrubs, trees and lianas
Economic botany – Study of plants of economic use or value
Ethnobotany – Plants and people. Use and selection of plants by humans
Floristics - The study of plants in a specific geographical region.
Forestry – Forest management and related studies
Horticulture – cultivation of garden plants
Marine botany – Study of aquatic plants and algae that live in seawater
Micropropagation – rapid propagation of plants using cell and tissue culture
Pharming (genetics) – Genetic engineering of plants to produce pharmaceuticals
Plant breeding – Breeding of plants with desirable genetic characters
Plant pathology (Phytopathology) – Plant diseases
Plant propagation – propagation of plants from seed, bulbs, tubers, cuttings and grafting
Pomology – Fruit and nuts
Seed technology - Seed technology is the science dealing with the methods of improving physical and genetical characteristics of seed.

Core topics

Cytology – cell structure
Epigenetics – Control of gene expression
Paleobotany – Study of fossil plants and plant evolution
Palynology – Pollen and spores
Plant biochemistry – Chemical processes of primary and secondary metabolism
Phenology – the timing of germination, flowering and fruiting
Phytochemistry – Plant secondary chemistry and chemical processes
Phytogeography – Plant Biogeography, the study of plant distributions
Phytosociology – Plant communities and interactions
Plant anatomy – Structure of plant cells and tissues
Plant ecology – Role and function of plants in the environment
Plant evolutionary developmental biology – Plant development from an evolutionary perspective
Plant genetics – Genetic inheritance in plants
Plant morphology – Structure of plants
Plant physiology – Life functions of plants
Plant reproduction – Processes of plant reproduction
Plant systematics – Classification and naming of plants
Plant taxonomy – Classification and naming of plants

Organismal topics

Groups of organisms — clades, grades and guilds

Study of chronological dating using plants

Acanthochronology – Cactaceae
Dendrochronology – Wood
