Abstract: Atriplex plants are an important forage reserves and their importance in the rehabilitation of degraded areas and saline soils (agricultural and ecological interest) its resistance to drought, salinity and sunlight [1,2]. In order to explore the mechanism of salinity tolerance of the plant, proposed by this study to identify the behavior of some cations following a salt stress applied during a week with salt combined NaCl + CaCl2 (400 and 600 meq), was studied in seedlings of Atriplex canescens (Pursh) Nutt. The nutritional aspect has been identified as a probable indication of tolerance to salt stress. The obtained results indicate that salinity has caused some changes in concentrations of cations. Na+ accumulates more in roots than in leaves and stems with increasing salt concentration treatment. The effect of salt treatment is a very highly significant accumulation of sodium in the three organs. The leaves of treated plants are enriched in K+ with increasing salt concentration with a very highly significant accumulation of potassium in the stem and root is not significant compared with controls. Regarding the Ca++ in the leaves, it increases significantly with increasing concentration of salt in the salt treatment, at the stem and root, calcium accumulates with low levels, the treatment effect is not significant.
