%X Uptake of Cl into Citrus leaf slices is decreased by external NO3. With 0.5 mM external CI, the decrease is smaller than that produced by equivalent amounts of Br, but with 10 mM external Cl the effects of NO3 and Br are similar. Uptake of NO3 is decreased by external Cl.    When slices are pretreated in KCl, KNO3 or KHCO3, giving high intracellular K salt concentrations, uptake of Cl and NO3 again decreases. Effects of internal Cl and carboxylates can be distinguished, and uptake appears to be altered by internal ion levels in a manner analogous to that previously demonstrated with other plant tissues. The suggestion that leaf cells may lack some of the regulatory systems present in roots is discussed.
