Özet: The environmental adaptation of the Chenopodiaceae (placed in Amaranthaceae s. l. in APG IV 2016) species is correlated with a physiological adaptation. Indeed, several species of this family are characterized by a C4 photosynthetic pathway. The aim of this work is to evaluate the lipid structure of two plant species of the genus Atriplex (halimus and canescens) in order to elucidate the effect of mineral nutrition on lipid peroxidation. Thus, the effect of three concentrations of Na Cl (100 300 and 600 mMl-1) was studied at the level of the two organs (roots and leaves) through the assay of Malondialdehyde (MDA) which represents a biomarker of lipid destruction. The results shows variability in the accumulation of MDA which indicate the variability of inter and intra specific responses. Nevertheless, the integrity of membrane lipids is little affected in both species and more in Atriplex halimus L.
