3.1.1 Morphological Observations
It was observed that S. hieraciifolia grown on the MS media could
survive under the excess salt stress condition (600 mM NaCl) though
chlorosis. Conversely, T. parvula could withstand the 450 mM NaCl
treatment but not the 600 mM NaCl treatment. The 300 mM NaCl caused
shoot succulence and the shoot succulence increased in accordance with
the enhanced NaCl concentration in S. hieraciifolia .
Additionally, the shoot length was down while shoot number increased in
the 300 mM NaCl treatment in S. hieraciifolia in comparison with
the 0 mM NaCl treatment. S. hieraciifolia and T. parvuladisplayed optimal growth at 300 mM NaCl (Figures 1 A-D).
