Popis:	Seedlings of three citrus rootstocks, sour orange (Citrus aurantiumL.; SO), Carrizo citrange (Citrus sinensis L., Osbeck x P. trifoliata L. Ref.; CA), and Macrophylla (Citrus macrophylla Wester; MA) were grown in nutrient solution and exposed for 60 days to different levels of salinity (0, 10, 20, 40, or 80 mM NaCl). The effects of the salinity treatments on growth, uptake, transport, and accumulation of Cl− and Na+ ions, in leaves and roots, were studied. Rootstock differences in leaf Cl− and Na+ concentrations were less evident at low salinity (10–20 mM NaCl) and clearly observed at higher external NaCl (40–80 mM NaCl). The most salt-tolerant rootstock was sour orange (SO), which experienced less growth reduction even when it accumulated high concentrations of Cl− and Na+ in the leaves. In addition, SO maintained the uptake and transport rates of ions similarly during the experiment, at all salinity levels. However, in Macrophylla (MA) and Carrizo (CA), at 40 and 60 days, the uptake and transpo...
