Samenanalyse

Samenanalyse refers to the systematic examination of seeds to determine quality parameters such as germination rate, purity, moisture content, vigor, and health. It is used in seed production, certification, trade, and research to ensure seed lots meet specification and perform reliably in agriculture.

Procedures follow established standards, notably guidelines of the International Seed Testing Association (ISTA) and national or regional seed laws. Seed analysts may test equipment calibration, sampling plans, and reporting formats. Results support labeling, certification, and decision-making for crop management.

Common tests include germination tests (assessing viable seedlings under defined conditions over a set period), vigor tests (rapid aging or other stress tests to estimate performance under adverse conditions), purity tests (proportion of pure seed versus inert matter, other crop seeds, or weeds), moisture content (oven or other methods), and seed-health tests (pathogens screening). Optional tests may include thousand-seed weight, seed color, and genetic purity.

The sampling process aims to obtain a representative sample from a lot, with defined sample size and stratification. Lab results are reported with specifications, lot identification, and tolerance ranges. Analysts interpret results to determine suitability for sale, certification, or planting recommendations.

Samenanalyse supports quality control across seed supply chains, influences price and labeling, and helps users compare seed lots. It also contributes to seed certification schemes and research on seed vigor and storage.
