Changes in all measured growth parameters and biochemical stress markers were analyzed in salt-treated plants with respect to the control, non-stressed plants of Plantago crassifolia (A), P. coronopus (B) and P. major (C), in correlation to EC (electrical conductivity) of the substrate, at the end of the four-week treatment. Abbreviations: number of leaves (NL), fresh weight percentage (FW%), water content percentage (WC%), sodium ions (Na+), potassium ions (K+), chloride ions (Cl-), sorbitol (Sor), proline (Pro), glycine-betaine (GB), total soluble sugars (TSS).
