R.  aCarbon dioxide assimilation and foliar ion concentrations in leaves of lemon (Citrus limon L.) trees irrigated with NaCl or NaSo4.h[electronic resource]  c1993  aAn attempt was made to differentiate between the possible effects of high Cl^- or Na^+ ions on lemon leaf photosynthesis by treating grafter (Citrus limon (L.) Burm. f. cv. 'Taylor) plants with eithr NaCl or Na2SO4 to establish different foliar concentrations of Na^+ and Cl^-. the rootstocks, Rangpur lime (C. reticullata var. austera hybrid?) and rough lemon (C. jambhiri), were chosen becaune Rangpur lime is known to be a good Cl^- 'excluder' and rough lemon to be a poor Cl^- 'excluder'. The grafted plants were initially treated for 7 weeks with nutrient solution (control) or nutrient solution containing 50 mol m^-3 NaCl or or 25 mol m^-3 NaSO4, after which time there were only marginal reductions in both photosynthetic rates and shhoot growth, with time theexception of 'Taylor' lemon on rough lemon roostock treated with NaCl where growth was affected more severely than the other treatments.  aCarbono1 aBLACKMORE, D.
