Atriplex halimus subsp. schweinfurthii, a widely distributed perennial halophyte in the Algerian salt steppes, is of interest because of its tolerance to environmental stresses and its use as a fodder shrub for livestock in low-rainfall Mediterranean areas. This study reports the effects of salinity (0, 4, 8, 12, 16, and 20 g l-1 CaCl2) on the growth, succulence, proline and ion content of the species under in vitro conditions. Fresh and dry weight of plants increased with an increase in salinity. Optimal growth was recorded at 8 g l-1 CaCl2; growth declined with increased levels of salinity. Ca2+, K+, Cl–, and proline contents in plants increased, whereas Na+ content decreased with an increase in salinity. Succulence of shoots and roots was significantly higher at CaCl2 concentrations of 12 to 20 g l-1 than at 8 g l-1 CaCl2. Water potential of plants decreased with an increase in salinity. This plant can be used locally as a fodder for livestock and to stabilise sand dunes and rehabilitate salt soils. |
