-1.2 MPa NaCl level in shoots and roots respectively as compared with control plants. While proline content was
markedly decreased in shoots of cotton plant, in roots it remain more or less unchanged up to -0.9 MPa NaCl level,
after this levels a reduction was recorded at -1.2 MPa NaCl level (Figure 3a; Figure 3b). In broad bean an
elevation trend with stable values was detected in shoots of broad bean plant starting -0.3 MPa NaCl level (Figure
4a; Figure 4b). In broad bean roots proline tended to decrease at -0.3 MPa NaCl level and progressively decreased
at -0.6 MPa, - 0.9 MPa and -1.2 MPa NaCl level (Figure 4). The percent of reduction at -1.2 MPa was 43.6% MPa
NaCl level. There is a smooth increase trend in shoots and roots of parsley plant, the percent of activation at -1.2
MPa NaCl level was 25% and 25.5% in shoots and roots respectively (Figure 5a; Figure 5b). Also, there is more
or less a stable trend in proline content of shoots maize, broad bean and shoots and roots of parsley plants.
