Spectral reflectance of partly transmitting leaves laboratory measurements and mathematical modeling

, : Spectral reflectance of partly transmitting leaves laboratory measurements and mathematical modeling. Remote Sensing of Environment 12(3): 247-254

Previous work related to remote sensing of natural sceneries has shown that the near IR signature of a plant canopy is a combined function of leaf optical properties, canopy geometry and soil reflectance. The problems involved in spectrophotometric measurements of leaves that are partly transmitting and partly reflecting, and thus influenced by the sample background provided by the measuring instrument, were examined. A mathematical model requiring only single-leaf spectral reflectance data as input was developed for prediction of multiple-leaf reflectance. The validity of the model appears to be adequate for any number of stacked leaves, when leaf-to-leaf variations caused by differences in water content and pigmentation are considered.

Beta(2)-adrenoceptor agonists such as fenoterol are anabolic in skeletal muscle, and because they promote hypertrophy and improve force-producing capacity, they have potential application for enhancing muscle repair after injury. No previous studi...
