Figure 1.

Changes in soil water content throughout the experiment shown for three individual Col-0 plants. Target soil humidity was set to 0.35 (WW; blue), 0.2 (MWD; red), and 0.15 (SWD; black) mg water g⁻¹ dry soil after the appearance of the first two true leaves. Fluctuations in soil humidity correspond to diurnal water loss via plant transpiration and evaporation from soil. Gray-shaded areas indicate periods of gravimetric water loss measurements (see “Materials and Methods”). Zenithal images of Col-0 rosettes from all three conditions highlight differences in rosette development between conditions at bolting (stage 5.10).
