Fig. 2

Graphical display of the relationships among the 20 investigated barley genotypes and 18 measured growth and physiological traits under salinity stress conditions. The different colors and intensities were adjusted based on associations among genotypes and traits. Colors are representative of a relative scale (− 3 to + 3) derived after data standardization. The darker green indicates lower values, while the darker red indicates higher values. RFW, root fresh weight; SFW, shoot fresh weight; SDW, shoot dry weight; SPAD, relative chlorophyll content; PN, photosynthetic rate; GS, stomatal conductance; TE, transpiration rate; MSI, membrane stability index; RWC, relative water content; RN, root Na+ content; RK, root K+ content; SN, shoot Na+ content; SK, shoot K+ content; RKN, root K+:Na+ ratio; SKN, shoot K+:Na+ ratio; RTSN, root-to-shoot Na+ translocation; RTKN, root-to-shoot K+ translocation
