A brief review on the development of the reflectance models based on radiative transfer in turbid medium is presented. The variants and modifications of these models are concerned, from the application of the K-M theory, the Duntley equations, the AGR model, to the well known Suits and SAIL models. Suits and SAIL models, tested in field trials, calculate the spectral reflectance of vegetation as a function of canopy biophysical and spectral parameters and of the viewing/illuminating geometry. The canopies are described through the area index of their components, mainly leaf area, with the plant architecture. Canopy single component spectral data were considered of great importance as quantitative basis for studies concerning spectral-agronomic relationships.
