title: An application of γ-scintigraphy to the observation of basipetal transport in moonflower.
abstract: A computer-monitored γ-ray camera was used to observe the basipetal transport of (99m)Tc-pertechnetate in moonflower Ipomoea alba L. Data collected in vivo at 1 min intervals from short, contiguous sections of stem indicated a strong apparent dependence of transport on water potential and are interpreted as supporting a turgor-driven mass-flow mechanism of translocation.
