Abstract
Bulk stomatal resistance of beans (Vicia faba L.,) as a function of so il water content was estimated for 41 days by comparison of potential transpiration, determined from meteorological data, and actual transpi ration, determined from soil water losses. The resistance of beans is about 46 s/m if soil water content is above 70% of available field cap acity and increases strongly in deer situations. This behaviour can be described by an exponential function.
