Abstract Accurate assessment of canopy carotenoid content (CCx+cC) in crops is central to monitor physiological conditions in plants and vegetation stress, and consequently supporting agronomic decisions. However, due to the overlap of absorption peaks of carotenoid (Cx+c) and chlorophyll (Ca), accurate estimation of carotenoid using
reflectance where carotenoid absorb is challenging. The objective of present study was to assess CCx+cC in winter
wheat (Triticum aestivum L.) with ground- and aircraft-based hyperspectral measurements in the visible and
near-infrared spectrum. In-situ hyperspectral reflectance were measured and airborne hyperspectral data were
acquired during major growth stages of winter wheat in five consecutive field experiments.… More >
