An attempt was made to differentiate between the possible effects of high Cl- or Na+ ions on lemon leaf photosynthesis by treating grafted (Citrus limon(L.) Burm. f. cv. 'Taylor') plants with either NaCl (C. reticulata var. austera hybrid?) and lemon (C. jambhiri), were chosen because Rangpur lime is known to be a good Cl- 'excluder' and rough lemon to be a poor Cl- . The 'excluder'. The grafted plants were initiallytreated for 7 weeks with nutrient solution (control) or nutrient solution containing 50 mol m -3 NaCl or 25 mol m -3 Na2SO4, after which time there were only marginal reductions in both photosynthetic rates and shoot growth, with the exception of 'Taylor' lemon on rough lemon roostock treated with NaCl where growth was affected more severely than the other treatments.Salinity levels were then doubled to 100 mol m-3NaCl and 50 mol m-3 Na2SO4 and the plants treated for a further 8 weeks, causing increases in leaf Na + and/or Cl- concentrations. Mature,3-4-month-old leaves of 'Taylor' lemon on Rangpur lime rootstock treated with Na2SO4 for this period,contained c. 105 mol m-3 Na+ and c. 10 mol m-3 Cl- and had photosynthetic rates 60% lower than controls. Simiar reductions in assimilation rate were seen in leaves on rough lemon roostock treated with NaCl containing c. 195 mol m -3 Cl-and c.35 mol m-3Na+. |
