Potted plants were exposed to D2O vapor in a greenhouse and uptake of D2O by leaf and deposition of D2O to pot soil were examined. Atmospheric D2O concentration in the greenhouse increased rapidly after starting the release and reached constant level in a few hours. Although the variation of D2O concentration in leaf followed that in air with showing a time delay, D2O concentration in leaf did not become the same level as that in air and vein showed lower concentration than lamina. D2O concentration in the pot soil increased slowly with diffusing in deeper layer.
