After 60 days of salinization, the young leaves of the preadapted
plants accumulated 10–12% less Na+ and Cl− than the
SC plants (Table 2, Fig. 2a and b). The A3 plants (−1MPa×3
days) showed the lowest concentrations of these toxic ions (50%
less than the SC plants). However, the plants from the treatments
B5 (−1MPa + 10mM NaCl×5 days) and D5 (−0.75
MPa + 10mM NaCl×5 days) registered 20–30% increases in
Na+ and Cl− compared to the SC plants, but with a very different
effect on fruit yield. In general, the most vigorous and
productive pre-adapted plants also presented the lowest leaf
Na+ and Cl− concentrations, although the opposite was also
found. For example, the highly productive C3 (−0.75MPa×3
days) plants (+50% in fruit yield) registered 20–35% less Na+
and Cl−, while those from treatment D5 (−0.75MPa + 10mM
NaCl×5 days) (+35% in fruit yield) showed a 20% increase
in these toxic ions, when compared to the SC plants. Interestingly,
the treatments inducing salt-inclusion included 10mM
NaCl in the composition of the incubation medium, in combination
with −1 or −0.75MPa and applied for 5 days
(Table 2).
