In order to optimise crop management, improve yield and quality, modern viticulture increasingly looks for reliable and fast methods to monitor plant physiology for early stress detection. Imaging technologies can be used for real time, non-invasive and non-destructive monitoring of grapevine physiological status. Thermal imaging allows us to measure the infrared (IR) radiation emitted by plants and to visualise spatial variation of their surface temperature. Recent developments extended the affordability and potential of thermal imaging in plant physiology and agronomy. Biological processes such as leaf transpiration can be monitored in real-time using thermal imaging. Thus, the technique can be used for continuous assessment of a plant’s physiological condition, and indirectly to detect the impact of non-optimal growth conditions (e.g. drought stress) on plant performance. The present paper briefly describes the principles behind thermal imaging and shows how it can be used for early stress detection, crop management and breeding in viticulture.
