The effect of saline ions (Сl−, SO4−2, and CO3−2) on the accumulation of chlorophylls in the leaves of new decorative tree-shrub plants introduced on salted Apsheron soils, their degree of salinity resistance, and the dependence of chlorophyll content on the types of saline ions are studied. A direct correlative relationship was established between the type of salinization and the accumulation of green pigments. It was revealed that toxic ions of chloride, sulfate and carbonate entering the root system and through it into the leaves of the studied species have a negative effect on the structure of chloroplasts, promote hydrolysis of protein compounds, breakdown of the protein-chlorophyll bond, accumulation of intermediate products of amides, cadoverin, putrescine and ammonia. The latter lead to tissue and their death.
