Salt stress reduces a seed's ability to absorb water (osmotic stress) and causes an ion imbalance within the seed (ionic stress), ultimately inhibiting germination and preventing crop production.Seed priming increases the vigor of seeds and seedlings through metabolic and biochemical processes occurring during controlled hydration, followed by dehydration. In the field, seeds are exposed to hydration-dehydration events in and on the soil after dispersal, as in seed priming.Does salt increase germination?In general, high soil salinity inhibits seed germination due to the low osmotic potential created around the seed, which prevents water uptake. In addition, high concentrations of sodium and chloride ions in the soil may be toxic to seeds
