Resumo: | The objective of this study was to evaluate the performance of different spectral indices - MCARI705, R750/R700, R750/R550 and MTCI - in the description of chlorophyll seasonal dynamics in detached leaves of Eucalyptus grandis in four seasons. The study was conducted in three plots of 600 m2, in a 20 months old stand. We collected 15 leaves from three layers of canopy, totalizing 45 leaves for each season. It was used a spectroradiometer FieldSpec®3, which covers the spectral range from 350 to 2,500 nm. Variance analysis (ANOVA) and Tukey test at 5% significance level were carried out. For all spectral indices, values observed in spring were different from those from summer; the same occurred between fall and winter. |

O trabalho foi realizado com base em três parcelas de 600 m2, em um povoamento com 20 meses de idade. Foram coletadas 15 folhas distribuídas em três camadas da copa, totalizando 45 folhas para cada estação. As leituras espectrorradiométricas foram realizadas com o espectrorradiômetro FieldSpec®3, que recobre a faixa espectral de 350 a 2.500 nm. Foi empregada a análise de variância (ANOVA) e o teste de médias Tukey ao nível de 5% de significância. Para todos os índices espectrais, os valores encontrados na primavera foram diferentes dos encontrados no verão; o mesmo ocorrendo entre outono e inverno.Embrapa Florestas2015-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/84110.4336/2015.pfb.35.82.841Pesquisa Florestal Brasileira; v. 35 n. 82 (2015): abr./jun.; 55-61Pesquisa Florestal Brasileira; Vol. 35 No. 82 (2015): abr./jun.; 55-611983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/841/414Copyright (c) 2015 Laura Camila de Godoy Goergen, Julio Cesar Wincher Soares, Elias Fernando Berra, Catize Brandelero, Rudiney Soares Pereirahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessGoergen, Laura Camila de GodoySoares, Julio Cesar WincherBerra, Elias FernandoBrandelero, CatizePereira, Rudiney Soares2017-04-28T12:44:45Zoai:pfb.cnpf.embrapa.br/pfb:article/841Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:44:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
