Abstract Short-term (16h) laboratory studies of 32p uptake by Elodea densa rooted in sediment demonstrated both foliar and root uptake, and that translocation occurred acropetally and basipetally. Root absorption is projected to provide 83-85% of total phosphorus uptake during 12-16th photoperiod days. Measured foliar uptake and excretion rates suggest that there would be no net leakage of phosphorus into the water by undamaged actively-growing E. densa. Foliar uptake decreased and root uptake increased in the dark relative to rates under light. (Copyright (c) Dr W. Junk Publishers, The Hague. Printed in the Netherlands.)
