Abstract The experiments were carried out in the Laboratory and pot experiments in the experimental farm of the Agricultural Botany Department, Faculty of Agriculture, Mansoura University during the period of 2008 and 2009, to understand and gain knowledge on the germination and seedling growth, plant growth, and phyotochemical constituents of soybean plants under( NaCl ) salinity (1500,3000 or 4500 ppm) or drought stresses (25%, 50% and 75% Field Capacity ; F.C) ; and how to minimizing the harmful effects through pre-soaking seeds in selected non-enzymatic antioxidants (ascorbic acid or α-tocopherol )at 50 or 100 ppm. The aim of the experiment was carried out to evaluate the effect of presoaking soybean seeds in selected non-enzymatic antioxidants (ascorbic acid or α-tocopherol at 50 or 100 ppm) on soybean seed germination and seedling growth under normal and stresses by NaCl or polyethylene glycol (PEG 6000) with different osmotic potentials of -2, -4 and-6 bars. |
