| Abstract: | Abstract The effects of increasing levels of NaCl in the irrigation water on the foliar content of N, P, K, Ca, Mg, Fe, and Mn of six citrus seedling varieties were studied. The experiment was carried out under greenhouse conditions in a factorial design. Treatments consisted of addition of irrigation waters containing 1.5, 10, 20, and 40 me NaCl/l. Increasing salinity significantly decreased K and Mn contents and increased those of N and Mg. Leaf content of P, Ca, and Fe was not affected. Results also showed that seedling variety and sampling data had a significant effect on the mineral composition of the leaf. |
