The objective of the present work was to identify the tolerance of barley varieties to salinity and
determine specific anatomical features of barley plants under saline conditions. Plants were grown in
hydroponic conditions in three variants: control, 50 mM NaCl and 100 mM NaCl. The tolerant and
sensitive varieties of barley to salinity were identified. The results show that salinity reduced the growth
and biomass accumulation of plants, reduced the thickness of the upper and lower epidermis, reduced
the diameter of the vascular bundles of leaves and the central cylinder of roots and increased the ratio
of exodermis/endodermis roots in some varieties.
