Abstract : Dry stress stomatal closure and leaf temperature increases occur parallel on most plants. Therefore, thermography offers a good possibility for getting an overview of spatial distribution and temporal transpiration development. This could be shown on mango trees in a glasshouse. Outdoors, numerous climatic influences affect leaf temperature; the variability within the treetop is more pronounced. For this reason models must be developed to be able to define the relationship between dry stress and leaf temperature under various conditions.
