A freeze-drying and non-aqueous extraction technique has been used to record the salt content of chloroplasts in leaf segments of Limonium vulgare. Changes in the level of K+, Na+ and Cl-were observed when leaf segments were treated with NaCl or KCl solutions which induce pumping of the salt glands. The effects of treatments designed to inhibit glandular activity are also recorded. Net accumulation of ions into chloroplasts is shown to be a process in vivo. The results provide evidence for a direct effect of glandular activity on cytoplasmic ion levels and they provide intracelluar evidence for the induction of glandular activity after a certain lag period. © 1970.
