| Abstract: | Summary Water flow in the stems of the horsetailEquisetum hyemale, the flowering plantStachys sylvatica and the mossDendroligotrichum dendroides was observed non-invasively using NMR microscopy. A Pulsed Gradient Spin Echo sequence using a single phase encoding step was used. We demonstrate by this method that water flow inEquisetum occurs in the carinal canals and in the xylem vessels of the vascular tissue ofStachys and in the central water-onducting strand ofDendroligotrichum.Abbreviations CPU central processing unit - ID internal diameter - NMR nuclear magnetic resonance - RF radio frequency - TS transverse section |
