Abstract | A reflectância espectral de dosséis de trigo (Triticum aestivum, L.) foi analisada em função de suas variáveis biofísicas, baseando-se em dados experimentais e em resultados do modelo SAIL, cujo potencial na investigação destas relações foi avaliado. O modelo SAIL calcula a reflectância da vegetação a partir de parâmetros biofísicos e espectrais do dossel e de parâmetros relativos a geometria de iluminação/observação. Os dados referem-se a 7 cultivares em 14 parcelas amostrais, localizadas em Planaltina (DF), sob manejo e irrigação uniformes. As medidas feitas com espectrorradiômetro abrangeram regiões do visível e do infravermelho próximo do espectro eletromagnético (de 547 a 823nm) e foram acompanhadas de levantamentos de dados agronômicos efetuados em 13 épocas ao longo do ciclo de desenvolvimento (maio a setembro de 1989). As reflectâncias do vermelho e do infravermelho próximo mostraram-se muito relacionadas ao IAF, através de regressão logarítmica, principalmente antes do IAF máximo. As variáveis levantadas no experimento foram aplicadas no modelo após serem complementadas por dados da literatura e as simulações tiveram comportamento semelhante ao dos dados observados. Os dados espectrais dos componentes de dossel foram considerados fundamentais como base quantitativa para estudos sobre as relações espectro-agronomicas. ABSTRACT: Experimental data and results of SAIL model supported a study relating the spectral reflectance of wheat canopies (Triticum aestivum, L.) to their biophysical parameters which included an evaluation of the model potential for investigating such relationships. The SAIL model calculates the spectral reflectance of vegetation as a function of canopy biophysical and spectral parameters and of the viewing/illuminating geometry. Data were taken over 7 varieties on 14 plots, placed in Planaltina (DF), under homogeneous management and irrigation schedules. The measurements taken from spectroradiometer in the visible to the near-infrared portion of the electromagnetic spectrum (from 547 to 823nm) and the agronomic data were determined together on 13 dates throughout the growing season (from May to September, 1989). The red and the near-infrared reflectance showed strong relationship to the leaf area index (LAI) under logarithmic regression, mainly before LAI reaches its maximum. The model was applied with experimental field data complemented by data found in literature, and the model simulations and the measured data had similar behavior. Canopy single component spectral data were considered of great importance as quantitative basis for studies concerning spectral-agronomic relationships. |
