Abstract: Field phenotyping conceptually can be divided in five pillars 1) traits of interest 2) sensors to measure these traits 3) positioning systems to allow high-throughput measurements by the sensors 4) experimental sites and 5) environmental monitoring. In this paper we will focus on photosynthesis as trait of interest, measured by remote active fluorescence in ‘BreedFACE’, an infrastructure for field phenotyping under elevated CO2 (eCO 2 ). The sensor used is the Light Induced Fluorescence Transient (LIFT) device mounted on a manual operated field4cycle positioning system. In direct response to eCO2 at 600ppm for winter wheat, NDVI and photosynthetic efficiency (Fq‘/F m ’) did not change whereas the QA reoxidation efficiency (F r2 /F m ) decreased at eCO2. This study further demonstrates the completion of BreedFAce with an example of proximal sensing of photosynthetic traits by the LIFT.
