Effects of seawater salinity on free amino acids and mineral ions inSuaeda nudiflora Moq.

  • A J Joshi

Variations in accumulation of free amino acids and mineral content in the succulent leaves ofSuaeda nudiflora in response to seawater salinity stress (10–40 mS. cm−1) have been studied. Alanine, aspartic acid, glutamic acid, glycine, phenylalanine, proline and serine were found in greater concentration than other amino acids. Under higher salinities, decline in concentration of aspartic acid and glutamic acid and increase in proline were observed. Massive accumulation of Na+ and Cl was recorded but salinity caused little variations of Ca2+, Mg2+ and SO 4 2− .
