		<abstract>The main objective that guides this research is the characterization of the spectral behavior of each soybean variety at laboratory level (spectroradiometer in the range 350-2500 nm). The study area is located in the municipality of Deodápolis, state of Mato Grosso do Sul. Spectral readings for each swatch soybean were made in model spectroradiometer FieldSpec 3 JR, which performs measurements in the spectral range of 350 nm to 2500 nm. Spectral reading of each sheet was used the equipment ASD Plant Probe. Spectral readings were repeated 3 times in the same plant varieties for BMX Potência (I), NA5909 (II) FT Campo Mourão (III) and Don Mario (IV). The drop in reflectance is associated with absorption by leaf pigments, mainly by chlorophyll. In the blue spectral region, the absorption occurs near the wavelength of 445 nm and is linked to the presence of xanthophyll pigments, carotenes, chlorophylls &#945; and &#946;; in the red region only chlorophyll acts by absorbing energy around 645 nm. In the near infrared range (NIR) of 700 to 1300 nm, an increase in reflectance values close to 50% due to the internal structure of the sheet (size and shape of the cells and the amount of intercellular spaces). From this point on, up to 2500 nm (infrared medium - IVM), there is a gradual decrease in reflectance showing some features of absorption by the liquid water content. The analysis of the spectral curves of soybean varieties allowed the characterization as the basis of several key points reflectance.</abstract>
