Pesquisa do Estado de Minas Gerais (FAPEMIG)A disserta??o foi dividida em dois cap?tulos, o primeiro referente ao embasamento te?rico da resposta vegetal a radia??o eletromagn?tica na regi?o do vis?vel e infravermelho pr?ximo e a rela??o da reflect?ncia com a estimativa de caracter?sticas de maneira n?o destrutiva por meio do uso de ?ndices de vegeta??o. O segundo sobre o uso de novos ?ndices de vegeta??o NI, PI, KI, CaI, MgI, SI, MnI, FeI, ZnI, CuI e BI na estimava do teor de macro e micronutrientes em eucalipto nas condi??es de viveiro, por meio do uso da reflect?ncia espectral. No trabalho foram coletados dados de reflect?ncia espectral, em folhas isoladas, nos materiais gen?ticos AEC 2034 ((Eucalyptus camaldulensis Dehnh x Eucalyptus grandis Hill (ex Maiden)) x Eucalyptus urophylla S.T. Blake) e AEC 2475 (Eucalyptus urophylla S.T. Blake x Eucalyptus pellita F. Muell) em minijardim clonal e produ??o de mudas aos 65 dias de idade. Os dados espectrais foram coletados com o mini espectr?metro foliar port?til CI-710 (CID, Inc., Camas, Washington, USA). As curvas espectrais no minijardim clonal foram estatisticamente iguais na faixa de 400 a 900, e estatisticamente diferentes na regi?o do violeta e azul e infravermelho pr?ximo. Na produ??o de mudas ?s curvas espectrais foram estatisticamente diferentes na faixa de 400 a 900 nm e em todas as regi?es avaliadas. Os ?ndices de vegeta??o apresentaram boas estimativas nas condi??es de minijardim clonal e produ??o de mudas, sendo poss?veis as estimativas por meio de ?ndices de vegeta??o no minijardim clonal e produ??o de mudas. Os ?ndices de vegeta??o que apresentaram as melhores estimativas do teor de nutrientes nas condi??es de minijardim clonal e produ??o de mudas foram os que atuam na regi?o do red edge.Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017.This work has been divided into two chapters, the first one refers to theoretical support regarding vegetation?s reaction to eletromagnetic radiation in the area of visibility and infrared surrounding it, and the relation of reflectance with an estimate of non-destructive characteristics by using vegetation indices. The second chapter is about the usage of new vegetal indices NI, PI, KI, CaI, MgI, SI, MnI, FeI, ZnI, CuI and BI in the estimate of macro and micronutrients level in eucalyptus under nursery tree conditions by using spectral reflectance. During the research, data from spectral reflectance was collected from isolated leaves, in the genetical material AEC 2034 ((Eucalyptus camaldulensis Dehnh x Eucalyptus grandis Hill (ex Maiden)) x Eucalyptus urophylla S.T. Blake) and AEC 2475 (Eucalyptus urophylla S.T. Blake x Eucalyptus pellita F. Muell) in clonal mini-garden and seedlings production of 65 days old. Spectral data was collected using a portable foliar spectrometer CI-710 (CID, Inc., Camas, Washington, USA). The spectral curves in the clonal mini-garden were statistically equal from 400 to 900 length, and statistically different in the violet, blue and ifrared surrounding area. In the seedlings production the spectral curves were statistically different from 400 to 900 nm and in all evaluated area. The vegatation indices presented good estimates under the conditions of clonal mini-garden and seedlings production, considering that the estimates were possible due to the vegetation indices in the clonal mini-garden and seedling production. The vegetation indices that showed the best estimate of nutrients content under clonal mini-garden conditions and seedlings production were the ones situated in the red edge area
