The article presents information on soil salinization as one of the widespread natural and partly anthropogenic stress factors. The main types of soil salinization, their features, and their distribution in the territory of Azerbaijan are described. Most Cl salts in the incoming water predominate, which leads to oversaturation and poisoning of plants. Hydrotechnical and phytomeliorative measures are necessary at the Main Shirvan Collector. The possibility of using the cluster analysis method to assess the specificity of biochemical adaptation of plants to different types of environmental salinization is shown. In article, for the first time, a cluster analysis of the results of a study of the performance of the antioxidant system of Triticosecale sprouts in response to short-term stress caused by the presence of sodium chloride in the medium at a concentration of 119 mM was carried out. The aboveground phytomass varies from 0.02 kg/m² in the most arid conditions under desertified steppe with low projective cover: 10–30% to 0.144 kg/m²; in the most typical conditions under steppe with projective cover of 40%, the aboveground phytomass is 0.040 kg/m.
