Abstract:
The excretion of ions by the glands on the upper surface of Limonium vulgare, Mill. (syn. Statice limonium) was studied by means of a short-circuit technique. The 'active' transport of sodium and chloride ions in an outward direction was demonstrated, the difference between these two ion transports being correlated with the short-circuit current. The inward transport of potassium ions was also demonstrated, together with the outward transport of rubidium, caesium, bromide and iodide ions. Evidence is produced that the alkali metal ion and halide ion transports are not independent, but are linked in a non-stoichiometrical manner. From measurements of the impedance of the leaf, the transglandular resistance has been calculated, and comparison with the ionic conductance of the glandular membranes shows that a serious discrepancy exists, as has been noted for many other biological tissues. The ion transport and the electrical properties are discussed in the light of modern theories and work on other materials.
