Abstract:
The plant growth, metabolisms, and productivity can be affected by the various
environmental stresses such as salin ity. The effect of sal inity stress on growth, activities
of antioxidants and p igments of Aglaonema simplex was investigated. The plantlets were .
cultured in MS medium containing NaCl at concentrations of 0, 100 and 200 mM for 30
days. The results showed the significant decreases of plant fresh weight specifically at
final treatment periods. The chlorophyl l content, total phenol, flavonoid, carotenoid, and
oc-tocopherol were decreased the concentration of NaCI increases especial ly at the longer
treatment periods. Moderate concentration of NaCI is suitable to enhance production of
secondary metabolites in A. simplex cultures.
