Résumé
Volkameriana lemon seedlings (Citrus limonia Osbec var0 Volkameriana) planted in six-inch pots were sprinkled with solutions containing four different concentrations on NaCl, Sprinkling was exercised intermittently and four levels of sprinkler application rate were used to study the effect of salinity and sprinkler application rate on + the uptake of Na and Cl by leaves* Salinity increase in sprinkled water caused a significant in- + crease of Na and Cl in the leaves. The detrimental effects of increased salinity may be eliminated by appropriate manipulation of sprinkler application rate. Increase in 4application rate may significantly reduce Na and Cl content of leaves In this respect application rate seems to be more effective with high salinity waters as compared to the low salinity waters. ++ -H- + No significant changes in the Ca . , Mg and K content of the leaves were observed by changing either salinity or application rate treatments. -V In most cases the increased concentration of Na and Cl in uncovered soil did not significantly increase concentration of these elements in the leaves. Sodium and chloride concentrations in the leaves suggest inconsistency of certain injurious limits with chemical composition of leave
