| Abstract | ||||
| The present study was carried out to show the negative impact of different concentrations of sodium chloride (100, 150, 200, 250 and 300 mM) on germination rate of 7-day old maize seeds, according to the results by measuring growth criteria of germinated maize seeds both 250 and 300 mM of Nacl these concs nearly lethal to maize seed so, both of concentrations ignored in next experiments and complete next step with three concs only (100, 150 and 200 mM) Nacl. Also, our study was accomplished to improve growth rate of 15-day old maize plant under different concentrations of sodium selenate (0.25, 0.5, 5, 10, 15, 20, and 25 μM), alpha-tocopherol (100, 150, 200, 250 and 300 ppm) and ascorbic acid (100, 150, 200, 250 and 300 ppm) each one alone, whereas growth parameter (shoot length, root length, fresh and dry weight of shoot and root, No. of leaves and leaf area per plant were estimated. The application of sodium selenate, alpha-tocopherol, and ascorbic acid each one alone by seed soaking resulted generally improve growth parameters of 15-day old maize plants as compared with untreated plants especially, 0.5µM of sodium selenate, 200ppm of alpha-tocopherol and 250 ppm of ascorbic acid. | ||||
