The ability of algae to withstand high salt concentrations is confirmed by numerous studies. Solonchaks, despite of the large number of dissolved salts, are usually inhabited by algae. Many researchers note changes in the amount and composition of algae, depending on the degree and type of soil salinization. The problems of salt tolerance in soil algae communities have been poorly studied and require the further study. Consequently, it was decided to conduct a series of experiments to study the effect of sodium salts on the microscopic green alga Scotiellopsis rubescens. Chloride and sodium carbonate, as salinization agents, were tested in the following concentrations: NaCl - 2x10-1; 3,5х 10-1; 5x10-1; 7x10-1; 1; 1.5 µ; Na2CO3 - 5x10-4, 1x10-3, 5x10-3, 1x10-2, 5x10-2 µ. When studying the effect of NaCl and Na2CO3 on S. rubescens, it was found that the most toxic was NaCl, the cells began to die already on the 3 rd day of the experiment, whereas when Na2CO3 was added, on the 7th day. Proceeding from the obtained result, a number of toxicity of salt solutions, introducing into the medium, corresponds to: NaCl> Na2CO3.
Keywords:Scotiellopsis rubescens, microscopic alga, salinization agents, sodium chloride, sodium carbonate, a number of toxicity.
