Table 2. Salt-induced leaf dehydration.

Leaf water content (%) after four weeks of treatment with increasing NaCl concentrations, in the three selected Plantago species (means ± SD, n = 5). Different lower case letters within each species indicate significant differences among treatments according to Tukey test (α = 0.05).
