ABSTRACT
A pot study was conducted to find out the wheat variety which can restrict the uptake of Na+ and CT- and prefer K+ under the dual stress of salinity and hypoxia. Matrix culture techniques were used to simulate the field conditions. Five wheat varieties were grown and salts (150 mol m-3 NaCl+ 15 mol m-3 CaCl2) were added to saline and saline-hypoxic treatments. Plants were harvested after a stress of four week and leaf sap was extracted from the youngest fully expanded leaf for Na+, K+ and Cl- determination. An increase in Na+ and Cl- concentration was observed in saline and saline-hypoxic treatments, while K+ concentration increased in saline and decreased in saline-hypoxic. Among the varieties, Blue silver and Chinese Spring showed a better control over ionic uptake compared with others.
