In order to study the interaction effects of salinity and ascorbic acid on the photosynthetic pigments, soluble sugar, proline, and protein in Satureja khuzestanica plant, factorial experiment was conducted in a completely randomized design (salinity in 4 levels 0, 40, 80 and 120g in 100kg soil and ascorbic acid in 2 levels 0 and 2 mM ) with 6 replicates. The results showed that salt stress reduced photosynthetic pigments amount by increasing the soil salinity from 0 to 40g NaCl in 100kg soil and then increased by 80g NaCl in 100kg soil and again decreased by concentration of 120g NaCl in 100kg soil. The amount of solouble sugar, proline and protein by the soil salinity increased from 0 to 40g in 100kg soil and then decreased in concentration of 80g NaCl in 100kg soil, in 120g NaCl in 100 kg soil increased amount of characters. In present of ascorbic acid photosynthetic pigments amount of pigments increased by increase the soil salinity from 0 to 40g NaCl in 100kg soil and then decreased by 80g NaCl in 100kg soil and again increased by concentration of 120g NaCl in 100kg soil. But, amount of solouble sugar, proline and protein by the soil salinity decreased from 0 to 40g in 100kg soil and then increased in concentration of 80g NaCl in 100kg soil. Finally, in 120g NaCl in 100kg soil decreased amount of characters.
