    Magnetic resonance imaging (MRI) was used to nondestructively observe changes in water content in roots of Pelargonium hortorum x Bailey during a period of relatively rapid transpiration. Anatomical regions of the root could be differentiated with a spatial resolution of 0.1 x 0.1 mm. MRI shows great potential for study of plant-water relations.
