WebChlorophyll absorbs red and blue, but reflects green light In addition, discrete wavelengths of light may be absorbed by different kinds of molecules. T he most common photosynthetic pigment, chlorophyll, absorbs both blue and red wavelengths of light, giving plants their characteristic green color. WebThe chlorophyll-a concentration in waters is one of the main parameters of water color remote sensing in case II waters. There is a reflectance peak in red band region …
WebOur objective was to investigate the spectral behavior of the relationship between reflectance and chlorophyll content and to develop a technique for non-destructive chlorophyll estimation in leaves with a wide range of pigment content and composition using reflectance in a few broad spectral bands. Web1.Introduction. The leaf chlorophyll content (LCC) is an important indicator associated with photosynthetic potential and nitrogen concentration in maize crops to guide site-specific field management (Sid'Ko et al., 2024, Sun et al., 2024).Visible and near-infrared (Vis-NIR, 325–1075 nm) spectroscopy plays an increasingly vital role in LCC detection with non …
WebThe absorption spectrum of chlorophylls includes wavelengths of blue and orange-red light, as is indicated by their peaks around 450-475 nm and around 650-675 nm. As a note, chlorophyll a absorbs slightly different wavelengths than chlorophyll b.
