The combined effect of salinity (NaCl) and copper ions on biomass and amino acid content in wheat varieties

Abstract

The article presents results of analysis of the joint and separate effect of salinity (NaCl) and copper ions (CuSO4) on biomass accumulation, and the amino acid content in the wheat varieties. At separate and joint effect of salinity and copper ions are reduced growth and biomass accumulation of wheat varieties. Identified resistant varieties of wheat to the effect of salinity and copper. On the accumulation of biomass by shoots Kazakhstanskaya-3 and Kazakhstanskaya rannaya weree more resistant to the combined effect of copper and salinity, and Shagala and Melturn - the most sensitive. The joint and separate effect of these stressors changes a content of amino acids such as glutamic acid, proline, valine, alanine, and the other aminoacids as a response protective reaction of plants.
