| The effects of increased NaCl salinity on growth, ion content and photosynthesis were studied in the halophyte, Plantago maritima L., cultured in controlled environment chambers. Shoot and root dry weight, leaf production and leaf length were all substantially reduced in plants grown at high salinity (350 mol.m;Plantago maritima is able to tolerate and quickly recover from exposure to large, transient changes in soil salinity. Reductions in photosynthesis caused by rapid increases in salinity were associated with shifts in the A-Ci curve that suggested inhibition of the mesophyll biochemical capacity. However, concurrent measurements of photosynthesis as oxygen evolution under 5% CO... |
