      abstract = {Catalase(CAT) (EC 1.11.1.6) is an important cellular  antioxidant enzyme that defends against oxidative stress.  Hydrogen peroxide, although not a free radical, is highly  reactive. It serves to protect the cell from toxic effects  of high concentrations of hydrogen peroxide by catalyzing  its decomposition into molecular oxygen and water, without  the production of free radicals. The effects of presoaking  of seeds in salt solution on germination and catalase  activity of Vigna radiata were studied. NaCl and  CaCl2soaked seeds showed reduced germination (less than  1cm) as indicated by decreased shoot length when compared  to controls. 5g seeds of Vigna radiata were presoaked for  24 hours in presence of NaCl (1, 5, 10, 15, 20 M) and CaCl2  (0.5, 1, 1.5, 2.0 M). After two days of germination, the  filtered water extracts (25 ml) were tested for qualitative  catalase activity. Further catalase assay of respective  extracts was monitored in terms of decay in H2O2  concentration at 240 nm (Jasco-V-530) and compared with the  decay in the absence of stress. There was nearly 40%  increase in extent of decay of H2O2at concentration of 1M  NaCl and 33.9% increase in decay at 1M concentration of  CaCl2. Further study includes different combinations of  NaCl and CaCl2to be tested followed by increase in  germination period and catalase activity monitoring in  partially purified and dialyzed extracts. There was an  enhancement of catalase activity in presence of the salt  stress.},
