Abstract
Abstract In the course of investigations on the impact of salinity on mineral ion transport in differentially salt susceptible soybeans (“Lee” and “Jackson”) short‐term experiments were conducted to elucidate the distribution pattern of Na + and some other cations. The results showed that low salinity (7.5 mM NaCl) did not induce varietal differences in Na + content during a 30 hrs uptake period. At 66.5 mM NaCl, however, the Na + contents increased more in the leaves of the salt sensitive variety “Jackson” than in “Lee”. Both soybean varieties retained Na + in the proximal root and stem. Furthermore, they extruded considerable amounts of Na + from the roots to the medium. Increasing the level of salinity in the solution substantially reduced the Ca 2+ uptake of both soybean varieties. In an experiment with the salt sensitive variety under constant salinity but increasing Ca 2+ concentration in the medium, the plants showed a reduction in Na + uptake and translocation to stem and leaves and an enhanced Ca 2+ uptake and translocation to the shoots. It is suggested that the injury observed in “Jackson” after salt treatment is not only related to the insufficient control of Cl − transport. At higher salinity levels the increasing accumulation of Na + in the leaves and the varietally independant depression of Ca 2+ uptake and translocation may enhance the development of leaf necrosis.
