Definition

Noun (Biology, Medicine) 1. The natural splitting or bursting open of a mature plant structure: The process by which a fruit, seed pod, or anther opens spontaneously at maturity to release its contents (e.g., seeds, spores, pollen). 2. The pathological or surgical opening of a wound: The rupture or separation of the layers of a surgically closed wound.

Usage

Dehiscence is a technical term used primarily in botany and medicine. It describes a specific type of opening, either as a normal, expected biological process or as a post-operative complication. - In botany, it is a key mechanism for seed dispersal. - In medicine, it is an undesirable event where a wound reopens.

Examples

• Botanical Context:
  • The dehiscence of the pea pod allows the seeds to scatter.
