This paper presents a field platform for continuous measurement of fluorescence at the canopy level. It consists 21-m-high crane equipped measurements. The is installed in middle fields dedicated to agricultural research. Thanks jib 24 m and railway 100 distance, measurements can be performed nadir viewing over various crops. development test future passive or active airborne space-borne vegetation sensors. A new fully automatic instrument, called TriFLEX, has been end jib. TriFLEX designed...
Sun-induced chlorophyll fluorescence (SIF) is a radiation flux emitted by molecules in the red (RSIF) and far region (FRSIF), considered as potential indicator of functional state photosynthesis remote sensing applications. Recently, ground studies space observations have demonstrated strong empirical linear relationship between FRSIF carbon uptake through (GPP, gross primary production). In this study, we investigated RSIF to represent status at canopy level on wheat crop. were continuously...
A field platform dedicated to fluorescence measurements (INRA, Avignon, France) was used monitor the emission of a sorghum during its growing period. The were performed continuously at canopy level, from seeding maturity. passive instrument based on three spectrometers evolution fluxes and vegetation indexes such as Photochemical Reflectance Index (PRI) Normalized Difference Vegetation (NDVI). Fluorescence retrieved radiances, using filling-in atmospheric oxygen absorption bands, 687 760 nm....
In order to evaluate the impact of water deficit in field conditions, researchers or breeders must set up large experiment networks very restrictive environments. Experience shows that half trials are not relevant because climatic conditions do allow stress scenario be tested. The PhénoField® platform is first based infrastructure European Union ensure protection against rainfall for a number plots, coupled with non-invasive acquisition crops' phenotype. this paper, we will highlight...
Abstract Photonics technologies play a crucial role in driving technological advancements within the agrifood industry, aiming to deliver sustainable food and agriculture, offering healthy, nutritious safe for all of us. Particularly, optical sensors imaging systems, together with machine-learning processing advanced lighting, pivotal monitoring crop soil health unprecedented precision, while safeguarding supply chain. This roadmap aims provide an overview state-of-the-art photonics...
Abstract As overfertilization leads to environmental concerns and the cost of N fertilizer increases, issue how select crop cultivars that can produce high yields on N‐deficient soils has become crucially important. However, little information is known about genetic mechanisms by which crops respond changes induced signaling. Here, we dissected architecture N‐induced phenotypic plasticity in bread wheat ( Triticum aestivum L.) integrating functional mapping semiautomatic high‐throughput...
Hyperspectral imaging techniques have been expanding considerably in recent years. The cost of current solutions is decreasing, but these high-end technologies are not yet available for moderate to low-cost outdoor and indoor applications. We used some the latest compressive sensing methods with a single-pixel setup. Projected patterns were generated on Fourier basis, which well-known its properties reduction acquisition calculation times. A low-cost, moderate-flow prototype was developed...
Abstract Chlorophyll fluorescence (ChF) is a relevant indicator of the actual plant physiological status. In this article different methods to measure ChF from remote sensing are evaluated: Fraunhofer Line Discrimination (FLD), Fluorescence Radiative Method (FRM) and improved (iFLD). The three have been applied data acquired in framework CarboEurope, FLEX Sentinel-2 (CEFLES2) campaign Les Landes, France September 2007. Comparing with situ measurements, results indicate that provide best FLD...
Digital and image analysis technologies in greenhouses have become commonplace plant science research started to move into the breeding industry. However, core of work takes place fields. We will present successive technological developments that allowed migration application remote sensing approaches at large field crop genetics physiology research, with a number projects taken France. These us develop combined sensor plus vector systems, from tractor mounted UAV (unmanned aerial vehicle)...
