Figure 5.

Gas-exchange parameters of GCHXK plants under salt stress. GCHXK and WT plants were planted in perlite (an inert growth substance) and allowed to become established and grow for 41 days. At the end of that period of time, we started irrigating half of the plants with 150 mM NaCl and continued to irrigate the other half of the plants with regular water. During this experiment, we measured transpiration, stomatal conductance and photosynthesis. Data given as means (± SE), n ≥ 8. Asterisks denote significant differences relative to the WT (t-test, * p < 0.05; ** p < 0.01).
