Summary: | The study aimed to calibrate the model 3-PG for Eucalyptus saligna in the region of Guaíba, RS for the following variables diameter at breast height (DBH), total height, wood volume and biomass of stem (branch, bark and wood). The study took place in the region of Guaíba, RS, and clonal plantations of Eucalyptus saligna in various spacings were used. Six different ages were selected along the crop cycle (2nd to 7th year). A forest inventory was carried out in 60 plants per plot for further collection of biomass (three trees fractionated into wood, bark, branches and leaves). The biomass of roots on the medium tree of each plot was measured to a depth of 1 m. Physical and chemical analysis were performed in the samples of soil in layers from 0 to 20 cm, 20 to 40 cm and 40 to 100 cm. Litter deposition was estimated by allocating 4 square wood collectors of 0.5 m². Leaf area was obtained through digital photographs and thus the specific leaf area was estimated. The physiological parameters were measured using the Li-Cor 6400 in six plots, one at each age. Climatic parameters were provided through the Agronomic Experimental Station of the Federal University of Rio Grande do Sul. Allometric and nonlinear equations adjusted for the fraction branch/bark, wood basic density and specific leaf area did not present a good adjustment because there was variability in the data used. Although the estimated values differed from the values observed, the model performance in terms of adjustment exceeded other parameterizations available in the literature. The parameterization and calibration of the model 3-PG were performed satisfactorily meeting all the predictions proposed by the model. The model validation was not statistically accepted, but their estimated data can be used as a source of estimates for the variables studied, demonstrating the potential of its use, however, the need for additional studies to better understanding of this species in this region. The use of the parameters raised by other authors in other regions cannot be used for the region studied. |

O estudo ocorreu na região de Guaíba, RS, sendo utilizados plantios clonais de Eucalyptus saligna, em diversos espaçamentos. Foram selecionadas seis idades ao longo do ciclo de cultivo (2º ao 7º ano). Realizou-se o inventário florestal em 60 plantas por parcela, para posterior coleta da biomassa (três árvores, sendo fracionadas em lenho, casca, galhos e folhas). Na árvore média de cada parcela, mensurou-se a biomassa de raízes até a profundidade de 1 m. Análises físicas e químicas em amostras de solo foram realizadas nas camadas de 0 a 20 cm, 20 a 40 cm e 40 a 100 cm. A deposição de serapilheira foi estimada através da alocação de quatro coletores quadrados de madeira de 0,5 m². A área foliar obteve-se através de fotografias digitais e, a partir destas, estimou-se a área foliar específica. Os parâmetros fisiológicos foram mensurados através do aparelho Li-Cor 6400, em seis parcelas, uma em cada idade. Os parâmetros climáticos foram fornecidos através da Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul. As equações alométricas e as não-lineares ajustadas para fração galho/casca, densidade básica da madeira e área foliar específica não tiveram bom ajuste, pois há variabilidade nos dados utilizados. Apesar dos valores estimados serem diferentes dos valores observados, o desempenho do modelo, em termos de ajuste, superou outras parametrizações disponíveis na literatura. A parametrização e a calibração do modelo 3-PG foram feitas de modo satisfatório, atendendo todas as predições propostas pelo modelo. A validação do modelo não foi estatisticamente aceita, mas os seus dados estimados podem ser utilizados como fonte de estimativa para as variáveis estudadas, evidenciando o potencial do seu uso, porém, com a necessidade de estudos adicionais para melhor compreensão desta espécie para esta região. O emprego dos parâmetros levantados por outros autores em outras regiões não pode ser utilizada para a região de estudo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia FlorestalUFSMBRRecursos Florestais e Engenharia FlorestalEcofisiologia florestalBiomassa florestalSerrapilheiraAlocação de carbonoModelagemForest ecophysiologyForest biomassLitterCarbon allocationModelingCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALCalibração do modelo 3-PG para Eucalyptus saligna Smith na região de Guaíba, RSCalibration the model 3-PG for Eucalyptus saligna in the region of Guaíba, RSinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSchumacher, Mauro Valdirhttp://lattes.cnpq.br/4577505947479643Vogel, Hamilton Luiz Munarihttp://lattes.cnpq.br/9394478619534442Muller, Ivanorhttp://lattes.cnpq.br/4178501394553328http://lattes.cnpq.br/7356987381643055Londero, Eduardo Kneipp50020000000340050030030050066a4f294-3de9-4e2f-a787-e09bce097e3b5b5dc17b-ad04-41c4-8f7a-5888e02c505517be2ea8-44f4-43c1-8ba2-0fa0f96655909066202f-f232-4891-b1b0-91c9d99972c9info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALLONDERO, EDUARDO KNEIPP.pdfapplication/pdf2015248http://repositorio.ufsm.br/bitstream/1/8685/1/LONDERO%2c%20EDUARDO%20KNEIPP.pdf420b392cf028d252aba3f1672ab47d87MD51TEXTLONDERO, EDUARDO KNEIPP.pdf.txtLONDERO, EDUARDO KNEIPP.pdf.txtExtracted texttext/plain97126http://repositorio.ufsm.br/bitstream/1/8685/2/LONDERO%2c%20EDUARDO%20KNEIPP.pdf.txt1538ee9bfca876d0e8e7270e80aa49c6MD52THUMBNAILLONDERO, EDUARDO KNEIPP.pdf.jpgLONDERO, EDUARDO KNEIPP.pdf.jpgIM Thumbnailimage/jpeg4810http://repositorio.ufsm.br/bitstream/1/8685/3/LONDERO%2c%20EDUARDO%20KNEIPP.pdf.jpg7d78c6d59612712320d731890f6715abMD531/86852022-08-18 14:39:28.907oai:repositorio.ufsm.br:1/8685Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-08-18T17:39:28Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
