Abstract

Recently Elytrigia atherica has extended its range to a lower range on the salt marsh. These lower salt marshes have a higher soil salinity. Simultaneously, the nitrogen content of the soil has increased. It is thought that a strategy for halophytes lies in the ability to accumulate nitrogen containing metabolite compounds. This implies a close relation between nitrogen and salt tolerance. Because E. atherica takes over when the nutrient availability increases like in the high marsh and the implication of the close relation of nitrogen and salt tolerance, we hypothesised that E. atherica can tolerate more salt when more nitrogen is available. We also hypothesised that E. atherica would accumulate nitrogen under saline conditions as this is a proven strategy for many halophytes. In this study we analysed the reaction of E. atherica to the combination of increasing salt and nitrogen. No influence of nitrogen on the salt tolerance of E. atherica was found. Salt however did have a great influence on the growth rate and survival.
