Adaptations to combined salinity and waterlogging stress were evaluated in two Suaeda salsa populations from different saline environments. Seedlings were exposed to 1, 200 and 600 mM NaCl in drained or waterlogged sand for 22 days in a glasshouse. Waterlogging did not significantly affect the K⁺/Na...
