Singlerooted

Singlerooted is an adjective used across disciplines to describe entities that possess a single primary root or root node. In botany and horticulture, singlerooted plants have a dominant main root (a taproot) that persists from germination, in contrast to fibrous-rooted species that develop many thin roots from the stem base. Singlerooted root systems are typically deeper, which can aid access to deeper soil moisture and nutrients and can influence stability. However, root architecture is plastic; environmental conditions, age, and cultivation practices can lead to changes such as the formation of adventitious roots or a more branched system. Classic examples often cited are taproot crops like carrots, beets, and radishes, which rely on a single prominent root for storage or forward growth.

In computer science and graph theory, a single-rooted or singlerooted tree is a connected acyclic graph with one designated root vertex from which all other vertices can be reached. This concept is used to model hierarchical data structures, file systems, organization charts, and parsing trees. The term helps distinguish from multi-rooted or unrooted graphs.

Usage notes: the spelling singlerooted is less common than the two-word form single-rooted; both appear in technical writing, and the term is not universally standardized. See also: taproot, fibrous root, rooted tree, graph theory.
