The exchange of sodium and potassium ions from root and leaf material of the halophyte Suaeda maritima was studied using efflux, or compartmental, analysis. Sodium ions were exchanged much more slowly (c. times) from the vacuoles of leaf cells of...

The time-course of exchange of Na and K ions from root and leaf material of the halophyte S. maritima was followed and the data analyzed according to the phenomenology of efflux, or compartmental, analysis. Na ions were exchanged much more slowly...

Salinity can cause toxic symptoms, especially in mature leaves after long-term exposure. Thus, Na(+) accumulation in leaves could be responsible for salt toxicity. The infiltration-centrifugation technique was employed for the isolation of apoplas...

In the course of investigations on the effect of salinity on mineral ion transport in soyabean cv. Lee and Jackson (more salt susceptible) the distribution of Na, Ca, K and Mg ions was studied. Low salinity (7.5 mM NaCl) did not cause differences...
