Optimum germination of Iva annua seeds occur at 15° C. Temperature and salinity interact in their effect on germination. Increases in osmotic concentration of media cause a gradual decrease in germination percentages at optimal temperatures. Sodium chloride, the most common salt in saline areas occupied by I. annua, has an osmotic rather than a toxic effect on germination.
