Resumo: | At this study were compared the mathematical models adjusted by regression analysis to define the productive capacity using curves site index for hybrid clones of Eucalyptus ssp., In the Araripe, Pernambuco. The study area was located at the Experimental Station of the Agronomic Institute of Pernambuco - IPA, located in the municipality of Araripina, Pernambuco. The data were measured from 45 permanent plots with 15 treatments (clones of Eucalyptus sp.) in three repetitions, with a spacing of 3 x 2 m plot area was 294 m2, with util area of 150 m2, in a block design The first measurement was performed at the time two months after planting to verify the survival, after the planting all plots were measured every six months, with measurements at 2, 6, 12, 18, 24, 30 , 36, 42, 48, 54, 60, 66, 72, 78, 84, 90 months. For each measurement were recorded the tree total height and the diameter at the breast height (DBH) of all trees. However this work did not consider the first four measures, because the plants were still young and therefore had not yet competition and also influence of the treatments were suffering forestry. Three models were to perform the analysis of covariance, Five linear and five nonlinear models were adjusted for the data collected, age and height . The adjusted models were evaluated through the following statistics and precision adjustment: adjusted coefficient of determination (R2aj), coefficient of variation in percentage, and residual graphical analysis in percentage. The differences in slope detected by analysis of covariance indicated, accurately among the fifteen clones tested, indicating the existence of nine groups with different growth patterns. It was considered necessary to adjust the nine sets of site index curves with reference age of 72 months, with an interval of 2 meters among the curves. All equations tested to estimate the growth in height according to age showed a good fit, especially for nonlinear models. For the establishment of the nine sets of site index curves, we selected the Schumacher model, for simplicity and to estimate the heights of trees and with only two parameters and, especially, for having made some better residual graphical distributions. |

A área de estudo estava localizada na Estação Experimental do Instituto Agronômico de Pernambuco – IPA, no município de Araripina, Pernambuco. Os dados foram medidos em 45 parcelas permanentes distribuídas com 15 tratamentos (clones de Eucalyptus spp.) em 3 repetições, com espaçamento de 3 x 2 m e área de 294 m² por parcela, com área útil de 150 m2 dispostas em delineamento casualizado em blocos. A primeira medição em altura foi realizada aos dois meses após o plantio quando foi avaliada a sobrevivência, posteriormente todas as parcelas foram mensuradas a cada seis meses, tendo ao final do experimento as medidas aos 2, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90 meses. Em cada medição foram registrados a altura total e o diâmetro a altura do peito (DAP) de todas as plantas presentes na área útil de cada parcela. Contudo neste trabalho não foram utilizadas as quatro primeiras medidas, pois as plantas ainda estavam jovens e, consequentemente, ainda não havia competição e também ainda estavam sofrendo influência dos tratamentos silviculturais. Foram selecionados três modelos e o que obteve os melhores resultados foram escolhidos para se realizar a análise de covariância .Foram ajustados 5 modelos lineares e 5 modelos não lineares para os pares de dados de idade e altura coletados, o quais foram avaliados por meio das estatísticas de ajuste e precisão: coeficiente de determinação ajustado (R2aj), coeficiente de variação em porcentagem (CV%) e análise gráfica de resíduos em porcentagem. As diferenças de inclinação detectadas pela análise de covariância indicaram, de forma precisa, entre os quinze clones testados, 9 grupos com diferentes padrões de crescimento. Foi considerado necessário o ajuste de nove conjuntos de curvas de índice de sítio, com idade de referência de 72 meses, com intervalo de 2 metros entre as curvas. Todas as equações testadas para estimar o crescimento em altura em função da idade apresentaram bom ajuste, com destaque para os modelos não lineares. Para o estabelecimento dos nove conjuntos de curvas de índice de sítio, foi selecionado o modelo de Schumacher, pelas estatísticas apresentada, pela simplicidade e por estimar bem as alturas das árvores com apenas dois parâmetros apresentando as melhores distribuições gráficas dos resíduos.Submitted by (lucia.rodrigues@ufrpe.br) on 2016-09-01T14:49:07Z No. of bitstreams: 1 Rubeni Cunha dos Santos.pdf: 2841897 bytes, checksum: 50ded5df9e65f22470ec0b1cf72a74bd (MD5)Made available in DSpace on 2016-09-01T14:49:07Z (GMT).
