Abstract
When bean leaves were exposed to tritiated water (HTO) vapor in a wind tunnel, the concentration of HTO in the leaves approached equilibrium in a few hours. The results are in good agreement with a model proposed by Belot, who assumed that HTO exchange is controlled by the rate of diffusion of the vapor through the boundary layer of the leaf and the stomata, and that the resistances for HTO and for water vapor are equal.
