Left: 11-week-old poplar seedling in sand. The intensity indicates the water content. Greater initial water uptake per unit root area is observed for the left side (of the chamber), which has younger, finer diameter roots. Right: water content based on measured NR (circles) or forward modeling using measured (black) or alternate (blue, orange) soil saturated hydraulic conductivities (Dhiman et al., 2018). In these studies, nR links root water uptake to characteristic root traits and can assess the performance of common water-uptake models. |
