Abstract
-1 ), two levels of Si (1.44 and 1.92 g.kg -1 soil) application and control (0 g.kg -1 soil) arranged as a split, split plot design. Salinity significantly decreased photosynthesis rate, chlorophyll a (Cha), chlorophyll b (Chb), and dry matter accumulation (DM) of the sorghum plants, indicating that plants suffered from stress. In addition, salinity imposed a remarkable decrease on variable fluorescence (Fv) and quantum yield. At highest level of salinity supply of 1.92 g.kg -1 soil Si, alleviated negative effects of salinity and increased photosynthetic rate (24%), transpiration rate (19%), quantum yield (38%), total pigments (22%) and dry matter accumulation (65%) compare with 1.44 g.kg -1 soil Si application. Correlation between shoot dry weight, Cha and Chb were no significant. In the relative salt sensitive CV (Sepideh) leaf Cha, Chb content and Cha/Chb, was higher than salt tolerance CV (Omidbakhsh), however, Omidbakhsh showed higher photosynthetic rate and dry matter accumulation.
