IGZ – Leibniz Institute of Vegetable and Ornamental Crops

Horticultural products should be of high quality and grown using environmentally friendly cultivation techniques. Vegetable plants are the basis of our most valuable food, but they must still be affordable to the consumer. Ornamental plants, likewise, affect the daily well-being of many people. The Leibniz Institute of Vegetable and Ornamental Crops (IGZ) works to establish and reinforce the scientific foundation of an ecologically sound and effective production of garden crops. Thereby we hope to support the environment, the grower competitiveness and consumer needs. We co-operate with universities, other research institutes and producers – in Germany, across Europe and around the world.

Our new Reseach Programm 2017-2020 started in January.

At the IGZ, scientists are engaged in a broad range of research topics that have scientific and practical relevance. Individual projects are assigned to Research groups which belong to specific Programme areas. These Programme Areas are: Functional plant biology (1), Plant-microbe systems (2), Plant quality and food security (3) and Horticultural systems of the future (4).
