文摘

Desmostachya bipinnata survived in up to 400 mM NaCl salinity. Plants treated with moderate salinity accumulated biomass comparable to control plants. Stomatal limitation did not influence CO2 fixation rates. Plants shifted from light harvesting to light protecting mechanisms at high salinity. Biochemical and photochemical limitation inhibited photosynthesis at high salinity.
