The leaf water content of the SC plants after 60 days of salinization
was 25% higher than in the non-salinized NSC plants
(Table 2). The pre-adapted population showed 16% less water
content than the SC plants (7.4 g g−1 DW) and values more
similar to the NSC plants (5.34). Indeed, the most productive
C3 plants also registered the lowest leaf water content (4.89).
The leaf Ψ decreased by 20% under salinity with respect to
the NSC plants (−1.02MPa). Although no differences were
found between most of pre-adapted and SC plants (−1.3MPa),
some relationship seems to exist between leaf Ψ and the
Na+ and Cl− contents among different pre-adapted populations
(Table 2).
