Leaf Reflectance vs. Leaf Chlorophyll and Carotenoid Concentrations for Eight Crops 1

摘要: Abstract Leaf reflectance in the 0.40‐to 0.75‐μm wavelength interval is influenced primarily by the pigments chlorophyll and carotenoid. However, the literature contains very few references to the relation between reflectance from leaves and their carotenoid content. Our objectives in this study were to determine which of three wavelengths in the visible spectral region best related leaf reflectance to total chlorophyll and carotenoid concentrations, and the relative effect of these pigments on reflectance. Hemispherical reflectances of single …
