                         reflect{\^a}ncia de doss{\'e}is agr{\'{\i}}colas (Suits e 
                         SAIL), foi instalado um campo experimental de trigo (Triticum 
                         aestivum, L.) em Campinas (SP). Analisaram-se as 
                         rela{\c{c}}{\~o}es entre os par{\^a}metros biof{\'{\i}}sicos 
                         e espectrais (medidos e calculados pelos modelos Suits e SAIL) e o 
                         ajuste dos modelos aos fatores de reflect{\^a}ncia bidirecional, 
                         para os comprimentos de onda compreendidos entre 400nm-900nm. 
                         Al{\'e}m disso, o desempenho dos modelos foi avaliado em 4 bandas 
                         simuladas do sensor Thematic Mapper (TM1-azul; TM2-verde; 
                         TM3-vermelho e TM4-infravermelho pr{\'o}ximo). A banda TM4 obteve 
                         a melhor correla{\c{c}}{\~a}o com os par{\^a}metros 
                         biof{\'{\i}}sicos ({\'a}rea foliar, peso seco de folhas, 
                         {\'{\i}}ndice de area foliar e biomassa). A banda TM3 foi a que 
                         obteve melhor correla{\c{c}}{\~a}o linear dos modelos Suits e 
                         SAIL com os fatores de reflect{\^a}ncia bidirecional medidos no 
                         campo e entre os modelos para {\^a}ngulo zenital de visada a 0º e 
                         a 30º. Os modelos superestimaram sistematicamente os fatores de 
                         reflect{\^a}ncia bidirecional medidos nas duas 
                         configura{\c{c}}{\~o}es de visada, indicando uma tend{\^e}ncia. 
                         Os modelos Suits e SAIL, tiveram desempenho semelhante nos 
                         comprimentos de onda do vis{\'{\i}}vel ao longo do ciclo 
                         fenol{\'o}gico do trigo. Apenas na banda TM4, as 
                         discrep{\^a}ncias entre os fatores de reflect{\^a}ncia 
                         bidirecional medidos e calculados pelos modelos foi maior no 
                         modelo Suits. Os modelos podem representar o fator de 
                         reflect{\^a}ncia bidirecional de um dossel desde que as 
                         caracter{\'{\i}}sticas deste dossel sejam fielmente descritas. 
                         ABSTRACT: With the objective of collecting biophyisical and 
                         spectral parameters to evaluate two canopy reflectance models 
                         (Suits and SAIL), an experimental field of wheat (Triticum 
                         aestivum,L.) was planted in Campinas (SP). The relations among 
                         biophysical and spectral parameters (mesured and calculated by the 
                         Suits and SAIL models) were analysed and, the adjust of the models 
                         to the bidirectional reflectance factors in the wavelength between 
                         400nm-900nm. Also the performance of the models was evaluated in 
                         four simulated spectral bands of the Thematic Mapper sensor 
                         (TM1-blue; TM2-green; TM3-red ans TM4-near infrared). The TM4 band 
                         reached the best correlation with the biophysical parameters (leaf 
                         area, dry leaf weight, leaf arca index and biomass). The TM3 band 
                         was the one that reached the best correlation of the models Suits 
                         and SAIL with the bidirectional reflectance factor measured at the 
                         field and between the models in the both view zenith angle (0º and 
                         30º). The models sistematicaly overestimated the bidirectional 
                         reflectance factors in the both view angle configuration , 
                         indicating a trend. The models Suits and SAIL had similar 
                         performance in the visible wavelenghts during the phenological 
                         cycle of the wheat. Just in the TM4 band, the discrepancy between 
                         the bidirectional reflectance factor measured and calculated by 
                         the models was bigger in the Suits model. The Suits and SAIL 
                         models can represent the bidirectional refiectance factor of any 
                         canopy, since the canopy caracteristics has been reliable 
                         described.",
