Abstract

Salinity as main environmental factor constrains the growth and production of cereals especially maize in all over the world. Its effects can be alleviated by various mitigants like gamma radiations. Therefore, a pot experiment was design with pre-sowing gamma irradiated maize seeds and different concentrations of salinity i.e., control (no salts), 50mM and 100 mM. Results indicated that salt stress negatively affect almost all morphological, biochemical characters with ionic imbalance because of augmented uptake of Na+ and Cl- contents in irradiated plants. However, gamma irradiated plants showed improvement in all morphological and biochemical parameters except shoot length and root fresh weight. It also increased the absorption of K+, Ca+ with reduction of Na+ ions in root and shoot.
