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.
