NaCI induced changes in organic constituents of Acanthus ilicifolius a salt marsh halophyte

Abstract

The present study pertains to the effect of exogenous addition of different concentration of NaCI ranging from 100 to 500 mM, to the one month old seedlings of Acanthus ilicifolius. Accumulaiton of organic constituents like amino acids and total sugars decreased with increasing concentration upto200 mM. Beyond 200 mM, they gradually increased. The proline content increased with increasing salinity upto the extreme level of 500 mM NaCI. The protein, starch and chloropyll content also increased with increasing concentration upto 200 mM and thereafter they gradually declined.

Keywords: Acanthus ilicifolius, Amino acid, Halophyte, Sugar
