The plants were subjected to six different treatments 1 (control) containing basic solution, 2 basic solution40mM of NaCl, 3 basic solution40 mM of KNO3, 4 basic solution20 mM of Ca(NO3)2.4H2O, 5 basic solution20 mM of Mg(NO3)2.6H2O and 6 basic solution20 mM of KNO35 mM of Ca(NO3)2.4H2O5 mM of Mg(NO3)2.6H2O. Membrane permeability was increased significantly only with addition of NaCl, and then decreased to its lower level with addition of Ca(NO3)2.4H2O and Mg(NO3)2.6H2O. Proline accumulation were followed the same trend of results when they had been exposed to NaCl salinity. Nitrate reductase activity (NRA) was significantly affected by addition of different types of nutrient induced salinity. </abstract> <index>Open Science Index 71, 2012</index> </article>
