Effects of priming on germination and biochemical attributes of three maize lines under saline condition

It has been shown that the adverse effects of salinity can vary between different varieties same plant species. This study was conducted to determine tolerability three newly released lines maize saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic (SA) each at 1.0 M concentration; seeds distilled water were used as control. Concentrations 0, 50, 100, 150 300 mM NaCl tested. The experiment followed a 3x3x5 factorial arrangement treatments replications. results revealed significant interaction where germination percentage line SWAN-LSR-Y much more affected than other level 50 mM, its speed others passing from NaCl. seedling lengths (radicle plumule) seed vigor index influenced by primer salinity, EDTA enhanced better growth primers did not exceed mM. OMR-LSR-SY show this concentration. Similarly, SA treated showed lower accumulation reactive oxygen species such superoxide anion radical (O2-), hydrogen peroxide (H2O2), well decrease in malondialdehyde (MDA) contents, most importantly BR9928-OMR-SR-Y lines. Catalase (CAT) dismutase (SOD) activities SWAN-LSR- Y upon application EDTA.
