Addition of abscisic acid (ABA) to the transpiration stream of leaves of Xanthium strumarium caused stomatal closure and, simultaneously, an independent reduction of CO2 assimilation. An attempt was made to identify the site of inhibition that had occurred, presumably, in the path of photosynthetic
