520			_aSalinity is one of the main reasons in the deterioration of arable landsIrrigation , fertilizers and other modern agricultural practices have increased salinity and sodicity so much that the ability of many soils to grow crops has been severely reduced and sometimes eliminatedThis work was carried out , in the National nstitute of Laser Enhanced Sciences , (NILES) , Cairo University during 2002 - 2003 seasonIn the present workWheat plants , Triticum asetivum , were grown in soil having different salinity levelsMixed amounts of NaCl , Ca Cl2 , and Mg SO4 with 1 : 1 : 05 ratios were added to the soil at concentrations of 2000 , 4000 , and 6000 ppmNa , Mg and Ca concentration in different parts of the plant (leaves , roots and grains) as well as soil at different growth stages (50 , 90 and 150 days from sowing) were determined in a control group which has been grown without any treatment , and in other groups treated by Si in the form of sodium meta silicate (Na2 Si O35H2O) These treatments were added to the soil and foliary (with two concentration 500 , 1000 ppm SiO2 for both methods) to reduce salinity hazardsSalinity effects on the plant growth , yield , and some certain physiological responses (total sugars , total free amino acids , total soluble phenols and plant pigments)
