The Leibniz-Institute of Vegetable and Ornamental Crops (IGZ) conducts excellent research in a broad range of fields related to horticultural sciences. Resource optimised cultivation of crops inside controlled environment horticulture (CEA) such as greenhouses is the main focus of the research group ‘Protected Cultivation’ within the Program Area ‘Horticultural Systems for the Future (HORTSYS)’
Damages to the physiological apparatus caused by plant stress are known to be reversible up to a certain point, while mild stress can have positive effects on plants in terms of harvest product composition and other quality parameters. A possible solution to detect stress would be to combine data information from sensors with plant physiological models to so called soft sensors. In that, the knowledge of leaf morphology and especially stomata conductance play a central role. Understanding and systematic analyses of the signals controlling stomata behavior and their incorporation in stomata-modelling is still lacking important bricks.
