Abstract
Nuclear Magnetic Resonance (NMR) and NMR imaging (MRI) offer the possibility to quantitatively and non-invasively measure the presence and movement of water.
Unfortunately, NMR hardware historically is expensive, poorly suited for plants, and, because of its bulk and complexity, not suitable for use in the field.
But does it need to be? We here illustrate how novel, small scale portable NMR devices can be used in a sensor-like fashion to assess sap flow towards terminal organs such as the bean pod (Phaseolus vulgaris), and to directly measure xylem sap flow by means of NMR velocimetry in a poplar tree (Populus nigra).
