Abstract

DOI: 10.26471/cjees/2025/020/324

Salinity is a global problem and salinity areas are constantly increasing because of poor-quality irrigation systems containing high concentration of dissolved salts, salt penetration, and water pollution. This study deals with the phytoremediation of salts from mine water using phytohormones auxin 1-naphthylacetic acid (NAA) and cytokinin (m-topolin) at a concentration 10-5 mol/l and common reed (Phragmites australis). The reed plants collected at the Lazy Mine were tested for their ability to accumulate salts from the surrounding mine waters. The experiment was carried out under controlled and controllable conditions in a phytotron. The hypothesis to be tested was a positive effect of phytohormones on the ability of the common reed to better accumulate salts from mine wastewater. The results show that the application of phytohormones in the long-range period, especially auxin, at a concentration of 10-5 mol/l could have a positive effect on the ability of reeds to accumulate salts from mine waters.
