Juurdumine

Juurdumine is the Estonian term for the development of a root system, most commonly used in botany and horticulture to describe the rooting of plant cuttings or seeds. The word combines juur, meaning “root,” with the suffix -dumine, indicating a process. In practical use, juurdumine refers to the plants establishing roots and becoming capable of water and nutrient uptake.

In propagation, juurdumine involves the formation of adventitious roots from non-root tissues, such as stems or leaves. This process is often influenced by hormonal signals, especially auxins, and by environmental conditions. Rooting success is highly species-dependent; some plants root readily, while others require specialized treatments or preconditioning to initiate root formation.

Techniques to promote juurdumine include using a well-draining rooting medium, maintaining adequate humidity, providing appropriate temperatures, and applying rooting aids containing auxins (for example, indole-3-butyric acid). Good hygiene, clean cuts, and proper sanitation reduce disease risk. The time required for roots to form varies from days to weeks depending on species, material, and conditions.

Applications of juurdumine are widespread in horticulture and forestry for vegetative propagation. It enables rapid production of genetically uniform plants, supports the establishment of ornamentals, fruiting shrubs, and trees, and is a fundamental tool for nurseries and researchers seeking reliable clonal propagation methods.
