Abstract

The present investigation was made to study the effect of different concentrations of sodium chloride on biochemical activity in different parts of Clerodendron inerme. The plant could survive a wide range of 100 to 500 mM of NaCl concentrations. The upper limit for the survival of this species was 500 mM NaCl. However, favorable growth response by seedling was confined to 200 mM NaCl. Biochemical compounds such as amino acid, sugar, protein, proline, glycinebetaine, and pigment chlorophyll content was increased up to 200 mM NaCl.

 

Key words: Halophyte, biochemical, salinity.
