1.3 Sodium
There is an interval increase between the five tested plants in sodium content of shoots and roots (Figure 1; Figure
2; Figure 3; Figure 4; Figure 5). The increase values in sodium content at -1.2 MPa NaCl level reach 26 - folds,
and 21.5- folds, 20- folds, 25- folds, 22- folds, 8- folds, 49- folds, 30- folds, 49- folds and 14.5- folds of shoots
and roots of maize, wheat, cotton, broad bean and parsley plants respectively. The higher values of increase in
sodium content were represented in shoots of parsley and broad bean plant. The opposite situation, the lower
values of increase was represented in shoots of wheat plants. The higher increase values in sodium content were
represented in the roots of broad bean plant. The lower increase values were represented in the roots of cotton
plants.
