Seedlings were exposed to various concentrations of CaCl2 and NaCl separately and standard concentrations were selected based on the growth. The experiments were carried out in the seedlings exposed to 75 mM NaCl, 10 mM CaCl2 treatments along with the combination of 10 mM CaCl2 and 75 mM NaCl. The control was maintain with distilled water. Experiments were carried out in two days interval upto 8th day from the transfer of seedlings to treatments. The seedlings exposed to 75 mM NaCl concentration showed slow growth (both shoot and root length) when compare to other treatments. Biomass production and Relative Water Content was found to be higher in CaCl2 treated seedlings. The seedlings under salt stress maintained less proteins and nucleic acids than that of CaCl2 and water and combination of NaCl with CaCl2. The experimental results indicate that the CaCl2 ameliorate the effect of NaCl stress by maintaining the Relative Water Content , protein and nucleic acids. Seedlings were treated with solutions of 75 mM NaCl, 10 mM CaCl2 and the combination of 75 mM NaCl with 10 mM CaCl2 during seedling growth from 2nd to 8th day after transferring at interval of 2 days. The growth and biochemical parameters include changes in the protein, DNA and RNA contents were studied in the seedlings. | | Keywords : | | - Sodium Chloride, Calcium Chloride, Vigna mungo, Growth, Protein, DNA and RNA.,
