Routine Testing Purity Analysis Purity Analysis determines the number or weight of contaminants found and reported at their respective rate of occurrence in a specific quantity.
Contaminants are noxious or common weeds, and other crop seeds.
Although not usually required for crop kinds in Canada, except for grasses, Pure Seed determines the actual percentage, by weight, of pure seed, other crop seeds, weed seeds and inert matter. This test is routinely performed for export purposes under A.O.S.A and I.S.T.A regulations. All domestic tests are conducted in accordance with the Canadian Methods and Procedures for Testing Seed. Germination Germination is a test that measures the seed's ability to develop into a normal healthy plant, under favourable field conditions. Two or four replicates, of seeds each, are taken from the pure seed fraction of the sample and germinated in optimum temperature controlled environments.
