    The present study was aimed to find out the changes in plant responses to salinity with GA3 treatments. With this aim, combinations effects of salinity (350 mM NaCl) and three different doses of gibberellic acid (100, 300 and 500 ppm) on physiological and biochemical analysis of maize (Zea mays L.) roots were studied in soil experiment. The obtained results showed that treatment of GA3 (300-500 ppm) caused a reduction in salt-induced damage, improvement in biomass yield, regulation in water status, increasing proline level, reactive oxygen species (ROS) scavenging capacity, induction of SOD (36.6% at 500 ppm), CAT (28.5% at 500 ppm), APX (3.18 and 3.26 fold at 100 ppm and 500 ppm), GST (2.83 and 2.59 at 100 ppm and 500 ppm) enzyme activities, while POX activity was decreased only at GA3 (31.3% at 500 ppm), and thus alleviation of the oxidative damage. The results indicated that the sa.. View More»
