Non-invasive field phenotyping
Non-invasive field phenotyping to quantify plant traits in response to changing environments.
Abiotic and biotic environment determines plant performance. We aim to quantify the above ground part of the plant, the so-called shoot, under natural or controlled (e.g. CO2, water) conditions in the field. Hereby we focus specifically on leaf photosynthesis and associated transport processes, canopy structure and functioning.
For non-invasive photosynthesis measurements we use the leaf fluorescence signal. Leaf fluorescence is quantified among others by the light induced fluorescence transient (LIFT) method. The LIFT and other sensors are positioned by custom made positioning system such as the Fieldsnake and Fieldweasel designed by us to have maximal flexibility but minimal impact when measuring in the field.
Our phenotyping efforts concentrate on crop species in Germany (e.g. Optiko) but also beyond (e.g. CASS). Therefore, we maintain fields with dedicated genotypes e.g. Phenorob central Experiment or Brainergy field as well as a Free Air CO2 Enrichment (FACE) facility for phenotyping under elevated CO2 concentrations in the field (BreedFACE) or the Photovoltaics systems integrated in the agricultural landscape in the project AgriFEE.
