Reassessment of tissue Na(+) concentration as a criterion for salinity tolerance in bread wheat.

Abstract excerpt

Wheat is the most important crop grown on many of world's saline and sodic soils, and breeding for improved salinity tolerance (ST) is the only feasible way of improving yield and yield stability under these conditions. There are a number of possible mechanisms by which cereals can tolerate high levels of salinity, but these can be considered in terms of Na(+) exclusion and tissue tolerance. Na(+) exclusion has...
