The use of native plants in urban landscape, especially in areas with saline and poor soils, plays a key role in water resources management and also in reduction of municipal landscape maintenance costs. In order to assess the effect of salinity stress on Nitraria schoberi as a native Iranian shrub, potted plants were irrigated with different levels of saline water (0, 20, 40, 60, 80 and 100 mM NaCl). Results showed that chlorophyll and sugar contents were not adversely affected by the salinity level. Proline content also was accumulated as a response to salt stress compared to control plants. Different salinity levels didn't significantly affect relative water content. Proline content did not increase significantly by salinity stress compared to control plants. The findings suggest that Nitraria schoberi is a really tolerant plant of salinity and it can be used as an ornamental plant in landscaping of semi-arid areas.
