Short Communication


Distribution maps of free water in germinating maize shoots were measured by an NMR microscope, and localization of water was assigned by superimposing1H-NMR micro-images on opital micrographs. In order to know physiological difference among tissues of the shoot, Mn2+, a strong paramagnetic reagent was applied on imaging. Change of the images affected by Mn2+ suggested that cell activity was higher in the first leaf than the other parts of the shoot of a 3 days old seedling.
