Abstract:
Salt stress is an abiotic factor limiting plant growth. Physiological mechanisms and metabolite impacts of the various cations and anions involved are addressed in this study. Assimilation rate and leaf water vapor conductance were reduced to approximately 25–30% without biomass reduction after 7 days salt stress, but this did not cause severe carbon shortage. The equimolar treatments of Na + , K + , and Cl − showed comparable accumulation patterns in leaves and roots, except for SO 4 2− which did not accumulate. We discovered several metabolic responses that were preferentially associated with the presence of Na + , K + , or Cl − . For example, increases of leaf proline and decreases of leaf fumaric acid and malic acid were apparently associated with Cl − accumulation.
