Effect of Different Concentrations of Sodium Cloride, Sodium Selenate, Alpha-Tocopherol and Ascorbic Acid Each One Alone on Germination and Growth of Maize Plant

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