Launsbacher Weg

The main task of the pot experiment station is to cultivate plants under near-natural conditions in different substrates or in water culture in the pot under varying experimental conditions. The testing of nutrient efficiencies of different genotypes or the investigation of resistance to plant diseases and abiotic stress of different genotypes can be carried out much more cost-effectively in vascular experiments than in field trials. A further task of the pot research station is for students to carry out their own experiments under supervision as part of their studies.
