Nasiona
Nasiona are tomato propagation materials that contain the complete genetic information needed for the development of a new plant. Their quality depends on the ripeness and health of the fruit, the method of seed extraction and cleaning, thorough drying, and storage conditions. Fermentation is a commonly used method for removing the gelatinous coating, but it is not a prerequisite for obtaining good seeds, and if carried out for too long, it can impair their quality. Properly stored tomato nasiona retain their germination capacity for many years.
