Resumo: | The near infrared spectral technology (NIR) is widely applied in the forestry sector, assisting in industrial processes, for instance, in the prevention of wooden structures, identification of wood, among others. The NIR used in the identification of wood, can assist in combating the illegal wood trade, especially Atlantic Forest native species. The technique of spectroscopy is combined with techniques of multivariate statistics, and this combination is known as Chemometrics. In this sense, the general objective of this research was to use the near infrared spectral technique to assist in predictions related to the use of wood, such as estimates of forest biomass, response to the xylophages attack and identification / differentiation of the wood species. Thirteen native species from the Atlantic Forest were used, from homogeneous plantations with 3 x 2 m spacing. Using chemometrics, statistical models were developed to estimate wood properties and identify species, through the translation of spectra through Principal Component Analysis (PCA), Partial Least Squares Regression (PLS), and Discriminant Function Regression (PLS-DA). In the separation and identification of the species, the model determination coefficients generated by the PLS-DA was 0,94 in the cross calibration and in the prediction of independent samples 0,92, with a prediction error of about 7%. Therefore, the use of predictive models based on the NIR spectra, was significant for both the discrimination and the identification of Atlantic Forest species analyzed. The estimation of aerial biomass by means of non-destructive methods was also studied to know the accumulated carbon stock. For this purpose, seven different dry biomass estimation methodologies were used, directly (destructive and non-destructive) and indirect (statistical models). The destructive method included rigorous weighing and cubing and the non-destructive method used basic density values estimated by the NIR spectroscopy technology and the X-ray densitometry (QTRS-01X Tree Ring Scanner). The models generated by PLS, for basic density estimated by NIR and X-ray, can be used to estimate aerial part biomass for the studied species. They presented different strategies for carbon accumulation, demonstrating the importance that forest management has on native species of the Atlantic Forest. Predictive models to distinguish the stages of biodegradation of four native species of white wood were also studied. Biodeterioration tests and chemical characterization were carried out to recognize the material. The statistical evaluation of mass loss was by the non-parametric test (Kruskal-Wallis). The species showed high natural resistance, being categorized as highly resistant to the fungus attack and presented a relationship with the extractive content. The predictive models corroborated with the results of the mass loss, discriminating with 100% precision in the presence of the fungus in the wood. Further studies are needed to expand the database, bringing robustness to the preliminary models generated by the PLS-DA, and increasing information on species with timber potential in the Atlantic forest, adding more justification to the management of this biome in relation to its economic viability with the conservationist. |

O NIR na identifica??o de madeiras, pode auxiliar no combate ao com?rcio ilegal das madeiras, especialmente as nativas da Mata Atl?ntica. Toda a t?cnica da espectroscopia ? combinada com t?cnicas da estat?stica multivariada, e essa combina??o ? conhecida como Quimiometria. Nesse sentido, o objetivo geral desse trabalho foi utilizar a t?cnica espectral do infravermelho pr?ximo, para auxiliar nas predi??es relacionadas ao uso da madeira, como estimativas de biomassa florestal, resposta ao ataque de xil?fagos e identifica??o/diferencia??o das esp?cies. Foram utilizadas ao todo 13 esp?cies nativas da Mata Atl?ntica, oriundas de plantios homog?neos com espa?amento 3 x 2 m. Com a quimiometria, foram desenvolvidos modelos estat?sticos para estimar propriedades da madeira e identificar as esp?cies, atrav?s da tradu??o dos espectros por meio da An?lise de Componentes Principais (Principal Componentes Analyse ? PCA), da Regress?o pelos M?nimos Quadrados Parciais (Parcial Last Square ? PLS ) e pela Regress?o por Fun??o Discriminante (PLS-DA). Na separa??o e identifica??o das esp?cies os coeficientes de determina??o do modelo gerado pela PLS-DA foi de 0,94 na calibra??o cruzada e na predi??o de amostras independentes 0,92, com erro de predi??o de cerca de 7%. Logo, a utiliza??o dos modelos preditivos com bases nos espectros do NIR, foi significativa tanto para a discrimina??o quanto para identifica??o de esp?cies da Mata Atl?ntica analisadas. A estimativa da biomassa a?rea por meio de m?todos n?o destrutivos, tamb?m foram estudadas a fim de conhecer estoque de carbono acumulado. Para tanto foram utilizadas sete diferentes metodologias de estimativa de biomassa seca, de forma direta (destrutivo e n?o destrutivo) e indireta (modelos estat?sticos). Pelo m?todo destrutivo, foi realizada a pesagem e cubagem rigorosa e pelo m?todo n?o destrutivo, foi utilizada valores de densidade b?sica estimada pela tecnologia da espectroscopia NIR e a densitometria de raio-X (QTRS-01X Tree Ring Scanner). Os modelos gerados pela PLS, para densidade b?sica estimada pelo NIR e Raio-X, podem ser utilizados para estimativa de biomassa da parte a?rea para as esp?cies estudas. Elas apresentaram diferentes estrat?gias no ac?mulo de carbono, demonstrando a import?ncia que o manejo florestal tem sobre as esp?cies nativas da Mata Atl?ntica. Modelos preditivos para distinguir os est?gios da biodegrada??o de quatro esp?cies nativa de madeira clara, tamb?m foram estudados. Foram feitos os ensaios de biodeteriora??o e a caracteriza??o qu?micas, para o reconhecimento do material. A avalia??o estat?stica da perda de massa foi pelo teste n?o param?trico (Kruskal-Wallis). A maioria das esp?cies demostraram alta resist?ncia natural, sendo categorizadas em altamente resistente ao ataque do fungo, e apresentaram uma rela??o com o teor de extrativos. Os modelos preditivos corroboraram com os resultados da perda de massa, discriminando com 100% de precis?o na presen?a do fungo na madeira. Novos estudos s?o necess?rios para ampliar a base de dados trazendo robustez aos modelos preliminares gerados pela PLS-DA, aumentando as informa??es sobre as esp?cies com potencial madeireiro da mata atl?ntica, agregando ao manejo desse bioma mais justificativas em rela??o a sua viabilidade econ?mica junto a conservacionista.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2022-05-06T19:34:01Z No. of bitstreams: 1 2020 - Jos?

description |
The near infrared spectral technology (NIR) is widely applied in the forestry sector, assisting in industrial processes, for instance, in the prevention of wooden structures, identification of wood, among others. The NIR used in the identification of wood, can assist in combating the illegal wood trade, especially Atlantic Forest native species. The technique of spectroscopy is combined with techniques of multivariate statistics, and this combination is known as Chemometrics. In this sense, the general objective of this research was to use the near infrared spectral technique to assist in predictions related to the use of wood, such as estimates of forest biomass, response to the xylophages attack and identification / differentiation of the wood species. Thirteen native species from the Atlantic Forest were used, from homogeneous plantations with 3 x 2 m spacing. Using chemometrics, statistical models were developed to estimate wood properties and identify species, through the translation of spectra through Principal Component Analysis (PCA), Partial Least Squares Regression (PLS), and Discriminant Function Regression (PLS-DA). In the separation and identification of the species, the model determination coefficients generated by the PLS-DA was 0,94 in the cross calibration and in the prediction of independent samples 0,92, with a prediction error of about 7%. Therefore, the use of predictive models based on the NIR spectra, was significant for both the discrimination and the identification of Atlantic Forest species analyzed. The estimation of aerial biomass by means of non-destructive methods was also studied to know the accumulated carbon stock. For this purpose, seven different dry biomass estimation methodologies were used, directly (destructive and non-destructive) and indirect (statistical models). The destructive method included rigorous weighing and cubing and the non-destructive method used basic density values estimated by the NIR spectroscopy technology and the X-ray densitometry (QTRS-01X Tree Ring Scanner). The models generated by PLS, for basic density estimated by NIR and X-ray, can be used to estimate aerial part biomass for the studied species. They presented different strategies for carbon accumulation, demonstrating the importance that forest management has on native species of the Atlantic Forest. Predictive models to distinguish the stages of biodegradation of four native species of white wood were also studied. Biodeterioration tests and chemical characterization were carried out to recognize the material. The statistical evaluation of mass loss was by the non-parametric test (Kruskal-Wallis). The species showed high natural resistance, being categorized as highly resistant to the fungus attack and presented a relationship with the extractive content. The predictive models corroborated with the results of the mass loss, discriminating with 100% precision in the presence of the fungus in the wood. Further studies are needed to expand the database, bringing robustness to the preliminary models generated by the PLS-DA, and increasing information on species with timber potential in the Atlantic forest, adding more justification to the management of this biome in relation to its economic viability with the conservationist. |
