Abstract

 In order to study the interactive effects of salinity and ascorbic acid with the quantity of photosynthetic pigments, soluble sugar, PROLINE and PROTEIN in Satureja khuzestanica plant, a factorial experiment was conducted in a completely randomized design (salinity at four levels of 0, 40, 80 and 120g in 100kg soil and ascorbic acid at two levels of 0 and 2 mM) with 6 replicates. The results showed that photosynthetic pigments amount was decreased by the increase of the soil salinity from 0 to 40g NaCl in 100kg soil, then increased by the salinity level of 80g NaCl in 100kg soil and then decreased by the salinity level of 120g NaCl in 100kg soil again. The amount of soluble sugar, PROLINE and PROTEIN was increased by the soil salinity levels of 0 to 40g in 100kg soil and then decreased by the salinity level of 80gNaCl in 100kg soil, and showed an increase at the salinity level of 120g NaCl in 100 kg soil. In the presence of ascorbic acid, the amount of photosynthetic pigments was increased by the increase of the soil salinity from 0 to 40g NaCl in 100kg soil and then decreased by the salinity level of 80g NaCl in 100kg soil and then increased by the salinity level of 120g NaCl in 100kg soil. However, the quantity of soluble sugar, PROLINE and PROTEIN was decreased by the increase of salinity level from 0 to 40g in 100kg soil, then increased by the salinity level of 80g NaCl in 100kg soil, and finally decreased by the salinity level of 120g NaCl in 100kg soil.
