Visualization of the root system architecture of plants is possible using a combination of magnetic resonance imaging of water mobility and tractography. Diffusion tensor imaging (DTI), a magnetic resonance application, was used to provide a three‐dimensional map of water mobility inside a pot containing soil and roots. Tractography generates channels that constitute pathways of facilitated water movement, representing the roots, calculated from water diffusion properties obtained from DTI experiments. Examples of pea ( Pisum sativum L.) and corn [ Zea mays L. var. indentata (Sturtev.) L.H. Bailey] root growth are provided.
