Implication

Comparative physiological study demonstrates that root potassium retention correlates with yield in wheat genotypes, highlighting potassium flux as a functional marker for salt-tolerance breeding.

Key Points

To determine whether root potassium (K+) retention correlates with salt tolerance and agronomic yield across bread and durum wheat genotypes.
Measured NaCl-induced root K+ flux kinetics in 6-day-old seedlings across two bread wheat and two durum wheat genotypes contrasting in salt tolerance using non-invasive microelectrode ion flux estimation (MIFE).
Compared laboratory root ion-flux measurements with whole-plant physiological traits and grain yield from mature plants grown under greenhouse conditions.
NaCl-induced K+ flux from seedling root surfaces was strongly correlated with mature whole-plant physiological performance and final crop yield.
Salt-tolerant genotypes demonstrated a significantly greater capacity to retain root K+ following salt exposure compared to sensitive genotypes, establishing K+ retention as a key determinant of wheat salt tolerance.
