Quality control consists in the inspection of seed plantations, both in the country and abroad. It takes place several times during the year when the plants blossom or fructify. We examine properties such as seed spacing (very important in the production of vegetable seeds since it guarantees purity of the variety) and the balance of morphological attributes. For ornamental plants, the inspection includes, among others, color of the flowers, habit of the plants and their height. If any plants differ from the specified attributes typical for the variety we have sown, they are immediately removed from the plantation.
