Résumé:
The objective of this work and to investigate the effect of salinity on changes and
physiological responses of a halophyte "AtriplexeCanescens (Pursh) .Nutt", and to study the
effect of this plant on the physicochemical properties of the salt soils of the plain of La Mina
(Relizane). This study was carried out in the field on a private farm, located in the El Matmar
area (Relizane).In order to conduct our experiment we divided the experimental plot. The two
parcels obtained concern the "control" plot and the other plot relates to the plot "Treated" by
the Atriplexecanescence. We then placed 03 sampling profiles, at the level of each plot, for
the follow-up of the experiment. In each profile, soil sampling is carried out up to a depth of 1
meter (0 - 25cm, 25-50cm, 50-75cm and 75-100cm) using soil auger. Also around each
profile three samples, at the plant level, were made (roots, stems and leaf) with three
repetitions. Thus, 48 soil samples and 18 plant samples were taken from two surveys and
analyzed in the laboratory.
