    Abstract

    The effects of NaCl salinity on growth, photosynthesis, transpiration and mineral composition of cotton plants grown in NH4+ or NO3- solutions at two CA2+ levels were studied. Salinity affected the growth of plants cultivated either with NH4+ or NO3-. Potassium uptake was decreased by high Ca2+ level and salinity. Reduction of Na+ concentration at high Ca2+ was observed. Salinity only affected photosynthesis in high Ca2+-ammonium-fed plants. Similarly, salinity only reduced transpiration and stomatal conductance in NH4+-fed plants. High Ca+2 did not ameliorate depressive effects of salinity, and no benefit was observed for NH4+-grown plants.
