In this work, tolerance of five genotypes of white poplar (Populus alba L.) on five concentrations of sodium chloride (1 mM, 3 mM, 10 mM, 33mM and 100 mM) in rooting medium was examined, based on 20 parameters that included biomass, photosynthetic and biochemical parameters. Concentration of 100 mM NaCl was inhibitory for biomass accumula- tion, content of photosynthetic pigments, total flavonoids content, total phenolics, increment of radical scavenging ability against ABTS+ and DPPH+radicals, the increment of sodium content, the decrement of potassium and magnesium content, and the increment of potassium/sodium ratio in shoots of examined white poplar genotypes. This and medium with 33 mM could be purposed for further research on salt tolerance in white poplar. It could be concluded that gen- otype L-80 is the most tolerant against salinity, and that examined parameters can be indicative for the selection of white poplar genotypes tolerant to salinity.
