Abstract Salt excretion by glands on the leaves of Leptochloa fusca was studied. The rate of excretion was strongly dependent on temperature up to 39°C, which is near the optimum for photosynthesis in this thermophilic C4 grass. The concentration of salt in the xylem required to sustain the observed rate of excretion was low (about two orders of magnitude less than the external concentration). Salt excretion is concluded to be a secondary mechanism of salt tolerance, with exclusion at the roots being the major mechanism. The rate of salt excretion was strongly dependent on temperature.
