Figure 4. Transpiration rate of AQP1xHK4 plants.
The rate of transpiration was monitored continuously throughout the day for each line (AQP1, HK4, AQP1xHK4 and WT). The presented data are the means ± SE for each 10th sampling point (n = 6). The transpiration data were normalized to the total leaf area and the amount taken up by the neighboring submerged fixed-size wick each day, which was set to 100%.
