3.1.4 Effects of Salinity on
H2O2 Content
H2O2 contents gradually increased inS. hieraciifolia and T. parvula while salt concentration
was increasing. H2O2 contents and the
rates of the increases observed in T. parvula were higher than
those of S. hieraciifolia . For example, there were 2.4-fold
increase in T. parvula and 1.8-fold in S. hieraciifolia in
the 300 mM NaCl treated shoots as compared with non-saline conditions.
Likewise, there were 8.3-fold and 4.4-fold enhancements in
H2O2 contents of the shoots treated with
450 mM NaCl in T. parvula and S. hieraciifolia ,
respectively (Table 1).
