The impact of salinity applied for five weeks followed two provenances of Atriplex halimus L. harvested from Oran (Algeria coast) and Ain Dheb (high plateaus west of Algeria). The analyzed parameters are physiological from the leaves of young plants grown in a greenhouse stored in air-conditioned glass. Two types of salt stress are imposed on plants from the 165th day after sowing for a batch CaCl2 + NaCl to 300 meq and 600 meq.l-1and for the other batch to undiluted water sea with a frequency of watering every other two days. The results of water indicators such as the relative water content (RWC or TRE) showed some fluctuation during the five weeks under the two types of stress. Transpiration (water loss from the excised leaf or RWL) measured after 30, 60 and 120 min at the end of the period of application of stress presents a decline in both sources and types of stress. In addition, the stomatal resistance showed considerable variability for both sources and the type of stress.
