Abstract

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.

Key words: Barley, salinity, growth, biomass, epidermis, exodermis, endodermis, vascular cylinder, central cylinder.
