Abstract	:	The lower Senegal valley is characterised by a deep water table and by the salinity of its water and soil, which is caused by capillary movement of salts to the surface. Among the species of native trees and shrubs, Tamarix senegalensis is noted as one of the best-adapted to this ecosystem. Its characteristics and its potential for use in the reclamation of saline soils is presently not well understood. Thus, the objectives of this research were oriented towards understanding its capacity for reforestation of saline soils. A first study evaluated the growth and nutrition of Tamarix senegalensis cuttings at seven different levels of additions of NaCl solution (0, 3, 6, 9, 11, 13 et 14 g L combined with the presence or absence of a rooting hormone (Stim-root N3) in the nursery. A second study examined the relation between increase in height and diameter and the nutrition of the species across a natural gradient of salinity on four sites. (Abstract shortened by UMI.)
