- Аннотация: Foliar pigment contents and composition are main factors governing absorbed photosynthetically active radiation, photosynthetic activity and physiological status of vegetation. In this study the performance of non-destructive techniques based on leaf reflectance were tested for estimating chlorophyll (Chl) and anthocyanin (AnC) contents in species with widely variable leaf structure, pigment content and composition. Only three spectral bands (green, red edge and NIR) are required for nondestructive Chl and AnC estimation with NRMSE below 4.5% and 6.1%, respectively. The algorithms developed are generic not requiring re-parameterization for each species allowing for accurate non-destructive Chl and AnC estimation using simple hand-held field/lab instrumentation. They also have potential in interpretation of airborne and satellite data.
