Black seed due to various therapeutic effects has long been considered as a medicinal plant, to investigate the effect of salinity stress on different ecotypes of black seed, a factorial experiment based on randomized complete block design with three replications in January .It took place at the Aboureihan campus of University of Tehran. Salinity treatment was considered at three levels as control, 5 and 10 dS / m. According to the comparison table, the mean salinity stress on chlorophyll, and proline was significant. Investigation of the effect of salinity stress on black ecotypes on chlorophyll traits showed that ecotype Razan and Zabol1 Khomeini and Ecotype showed the least. Analysis of proline showed that stress had the highest amount of proline which had significant difference with stress and control.
