zaadtype

Zaadtype is a term used in the seed trade and horticulture to denote a classification that groups seeds by shared physical and functional traits, beyond the species or cultivar designation. The term is derived from the Dutch word zaad (seed) and type (type) and is encountered in Dutch- and Afrikaans-speaking contexts as well as in international seed catalogs that use Dutch nomenclature.

Usage and criteria: Zaadtype categories may be based on seed size and shape, seed coat characteristics (for example, pelleted or coated seeds versus bare seeds), endosperm type, and dormancy status. They can reflect germination requirements such as light sensitivity, cold stratification, or after-ripening needs. Viability and vigor indicators and typical storage behavior may also define a zaadtype.

Applications: In catalogs and packaging, zaadtype helps buyers compare seeds with similar handling and germination profiles. It supports quality control, seed treatment decisions, and sowing planning by farmers and gardeners, and can aid breeders in selecting seed lots with consistent performance.

Relation to other terms: Zaadtype is not a substitute for variety, cultivar, or species; rather, it is a supplementary classification focused on seed properties and practical handling considerations.
