Effect of NaCl Stress on Pigment and Biochemical Changes in Cyamopsistetragonoloba (L) Taub (var. Pusa Naubahar)

Abstract

Abstract
In this study, effect of salinity on biochemical parameters in Cyamopsis tetragonoloba (L) Taub was studied. Plants were grown for 14 days in the controlled growth room. Pigments and biochemicals were extracted from leaves of control and NaCl-treated plants after seventh and 14th days of treatment. NaCl solutions at different osmotic potentials (0, 50, 100, and 150 mM) prepared by adding varying amounts of NaCl to the main culture solution were applied to plants from the beginning of the germination. As a result, the pigments, protein and nitrate reductase activity decreased, phenol; proline and total amino acid increased with increasing NaCl stress.
