Physiology of Yukon Thellungiella plants subjected to salt treatments. A) Water relations of Yukon Thellungiella exposed to NaCl. Plants were salinized step-wise by increasing the concentration of NaCl in 50 mM increments. Leaf ψ_W and ψ_S measurements were taken after 3 d of acclimation to each salt concentration. The ψ_P was estimated as the difference between ψ_W and ψ_S. Values are means of six individual plants ± SE. B) Leaf proline content of Yukon Thellungiella subjected to NaCl treatments or sampled at the field site in 2003 and 2005. Values are means ± SE from five individual plants.
