000857780 520__ $$aField 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 measurementsby the sensors 4) experimental sites and 5) environmental monitoring. In this paper we will focuson photosynthesis as trait of interest, measured by remote active fluorescence. The sensorpresented is the Light Induced Fluorescence Transient (LIFT) instrument. The LIFT instrument isintegrated in three positioning systems. First in an automatized rail based positioning systemmoving in x, y and z direction above 120 miniplots. Miniplots are large (0.8m2) soil-filled containersplaced inside and outside the greenhouse. Second the sensor is mounted on a manual operatedField4cycle and third on a fully autonomously moving, engine driven, GPS steered cart, calledFieldCop. Photosynthetic traits were quantified for major crop species across seasonal changesin environment, grown at elevated CO2, or at different irrigation regimes. The quantum efficiencyof photosystem II (Fq’/Fm’ )was light dependent whereas the electron transport rate efficiency(Fr2’/Fm’) was temperature dependent. Mean values of these photosynthetic traits or theirinteraction with environment allowed for characterization of different phenotypes. The LIFTinstrument combined with selected positioning system provides high throughput proximal sensingof novel photosynthetic traits.
