3.2.10 Effects of Salinity on Ascorbate and Glutathione
Contents
The total ascorbate concentration no significantly changed in the shoots
treated with 150 mM NaCl. However, the 300 mM NaCl and further salt
concentrations (450 and 600 mM) significantly increased the total
ascorbate content in comparison with 0 mM NaCl treatment. As compared to
the 0 mM NaCl treatment, there were 2.2-fold and 8-fold increases in ASC
content of the shoots treated with 300 mM and 600 mM NaCl, respectively
(Figure 4A).
Total glutathione content gradually enhanced while salt concentration
was increasing in S. hieraciifolia . There were 3.4-fold and
10-fold increases in GSH content of the shoots treated with 300 mM and
600 mM NaCl in comparison with the 0 mM NaCl treatment respectively
(Figure 4B).
