Seed testing is performed in dedicated laboratories by trained and usually certified analysts. The tests are designed to evaluate the quality of the seed lot being sold. Several tests are done:
- Germination test: Reports the percentage of seed that germinated. Tests are usually made in 200 or 400 seed samples.
- Purity test: The percentage of seed described on the label that is actually found in the quantity of seed.
- TZ test: A test for viability that involves soaking the seed in a tetrazolium solution, cutting the seed open, and looking for a color change in the seed embryo.
- Weed test: Examines a sample of seed and identifies every seed that is different from the seed that is different from the labelled seed kind.
