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