| description | The planting of native perennial woody species tolerant to variable salt concentrations can facilitate the recovery of degraded dry forests. The objective of this study was to evaluate and compare, under experimentally controlled conditions, the response to saline of young plants from four provenances of Prosopis alba, a mesquite species useful for restoration plans. The seeds of P. alba were from different localities of the Chaco region of Argentina (Santiago del Estero, Chaco, Formosa, and Salta). The plants were evaluated for 45 days under greenhouse-controlled growth conditions in the presence of 0, 100, and 300 mmol·L 1
NaCl. We measured variables associated with growth, photosynthesis, and redox state. The imposed salt stress condition did not cause plant death in any provenance. However, salinity produced a strong effect on growth and physiological variables of all provenances. Salta provenance was associated with higher net values of biomass and stemdiameter. Chaco registered the greatest relative values of height and stem diameter, indicating a higher salinity tolerance than the other provenances. Chaco also produced more antioxidants to cope with the oxidative stress associated with saline stress. Chaco and Salta provenances may be the most promising for use in restoration plans of dry forests in areas with saline soils in the Chaco region. We emphasize the importance of using different provenances in forest restoration for a more successful system recovery. |

La plantation d’espèces ligneuses pérennes et indigènes, tolérantes à diverses concentrations de sel, facilite la récupération des forêts sèches dégradées. L’objectif de cette étude consistait à évaluer et comparer, dans des conditions expérimentales contrôlées, la réaction au stress causé par le sel de jeunes plants issus de quatre provenances de Prosopis alba, une espèce demesquite utile pour les projets de restauration. Les graines de P. alba provenaient de différentes localités dans la région de Chaco en Argentine (Santiago del Estero, Chaco, Formosa et Salta). Les plants ont été évalués pendant 45 jours dans des conditions de croissance contrôlées en serre en présence de 0, 100 et 300 milli-moles de NaCl. Nous avons mesuré les variables associées à la croissance, la photosynthèse et l’état d’oxydoréduction. La condition imposée de stress salin n’a pas causé demortalité peu importe la provenance. Cependant, la salinité a eu un effet important sur la croissance et les variables physiologiques de toutes les provenances. La provenance Salta était associée à des valeurs nettes de biomasse et de diamètre de la tige plus élevées. Les plus grandes valeurs relatives de hauteur et de diamètre de la tige, l’indication d’une tolérance à la salinité plus élevée que celle des autres provenances, ont été observées chez la provenance Chaco. Cette provenance produisait aussi plus d’antioxydants pour faire face au stress oxydatif associé au stress salin. Les provenances Chaco et Salta pourraient être les plus prometteuses pour l’utilisation dans les projets de restauration des forêts sèches dans les zones de la région de Chaco où l’on trouve des sols salins. Nous insistons sur l’importance d’utiliser différentes provenances dans la restauration des forêts pour avoir un système de récupération qui a davantage du succès.
