The translocation of phosphorus by the aquatic vascular plant Najas minor All. was examined using radiophosphorus (32P). Whole plants showed a lack of phosphorus translocation either from the root to the shoot or in the reciprocal direction. Autoradiographic experiments indicated that the lack of translocation may be due to a very slow movement of this nutrient in both the root and the shoot. Phosphorous was calculated to move 0.6 mm/hr in roots and 1.2 mm/hr in foliage presumably through cells rather than in the vascular system.
