In vitro modulation of antioxidant and physiological properties of white poplar induced by salinity
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 o...

| Summary: | 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 accumulation, 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 genotype 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.
