Influence of Potato Leaves Variety on the Spectropolarization Characteristics of Leaf Reflected Radiation

Abstract

Studies of the spectropolarization characteristics angular dependencies of radiation reflected by the plant leaves allow to investigate the mechanisms of reflected radiation flux formation: the specular reflection on the leaf surface, the singly and multiply scattering within leaf, the leaf pigment absorption, and the cuticle refraction of radiation going out from the leaf. The polarization characteristics are most sensitive to the changes of plant structure as compared with the other factors. We have discovered and theoretically substantiated a spectral shift of a maximum of the polarization degree angular dependence.
