Plant biologists at Technische Universität Braunschweig are investigating the health of oak and beech trees in the face of global climate change. The aim is to develop ways of improving the trees’ natural immune defences based on sulphur. The scientists will not only study the plants in the laboratory, but will also carry out large-scale experiments in the real forest laboratory. The Institute of Plant Biology at TU Braunschweig, the Julius Kühn Institute, the Niedersachsen State Forests and a local industrial partner have joined forces for the project. The Federal Ministry of Food and Agriculture is funding the research with around 1.1 million euros.
