Gas exchange after mechanical damage and under stress conditions. a Photosynthetic carbon assimilation rate and b transpiration rate of a Col-0 plant from which the roots were cut 5 h into the light period. The measurements were repeated for three plants; the data for one representative plant are shown. c Photosynthetic rate and d transpiration rate of Col-0 plants under salt stress. All plants were measured for 6 h in the light period before treatment with 50 mM NaCl (pale gray triangles), 200 mM NaCl (dark gray diamonds), or left untreated (black squares). Open bars indicate the light period, solid bars the dark period. Mean ± SE (n = 4)
