Fourteen Copaifera multijuga trees were sampled to extract the oleoresin with the use of a compact BT 45 driller, at 1 meter high. Dendrometric information was collected from the tree trunk (size, chest height diameter-DBH, commercial and total heights, age of individuals and Mean Annual Increment (IMA). Edaphic soil characteristics (20 cm depth) were obtained around each tree. Then, a descriptive analysis was then performed with the observed variables. After this, the Principal Component Analysis (PCA) of the soil variables was applied, aiming to select the most important variables and to reduce the number of variables. Pearson???s correlation analysis was performed with the selected soil variables and the dendrometric and oil production variables. New PCA was made, including the selected soil variables, the dendrometic and oleoserin production. To know how the copaibeiras resemble all the measured variables, a hierarchical cluster analysis was made, using the Euclidean distance and the Ward cluster method. The results indicated that the 14 analyzed trees produced oil, with an average production of 226.79 ml ?? 126.91 (95% CI, n=14.). The most significant variables in this research were Age, MAI (Mean Annual Increment), Coarse Sand, Total Height, and amount of oil. The C. multijuga trees average age was 100.36 years ?? 11.88 and it was noticed that there was a low correlation between age and oil production. It was also observed that the higher the age of the trees, the higher the DAP. The amount of oil showed to be negatively correlated with the manganese content in the soil, although the Mn concentration is not beyond the plant???s tolerable limits, not representing toxicity risk. In the analyzed variables general context, age, Mean Annual Increment, coarse sand, clay, and oil quantity accounted for approximately 84% of the variability of the data set analyzed. Cluster analysis, in the context of all variables, evidenced the formation of three groups, where it can be observed that the geographical distance between individuals does not influence its cluster, from the point of view of measured biotic and abiotic similarity. It must be stand out that in general, the plasticity of copaibeiras has been observed to occur in the various concentrations of the analyzed variables, which suggests that this species has adapted to different soil conditions, and which additional studies should be carried out with a larger number of samples to support such observations. Este trabalho foi desenvolvido no Munic??pio de Manicor??-AM e teve por objetivo determinar como as vari??veis dendrocronol??gicas, dendrom??tricas, ed??ficas e de produ????o de oleorresina de copaiba (Copaifera multijuga), interagem entre si, e com a pr??pria produ????o de ??leo, com o intuito de contribuir para o avan??o do conhecimento sobre o manejo de copaibeiras naquela regi??o. Foram amostradas 14 ??rvores de Copaifera multijuga para extra????o do oleorresina com o uso de um perfurador compacto BT 45, a 1 metro de altura. Do tronco das ??rvores foram coletadas informa????es dendrom??tricas (porte, di??metro a altura do peito-DAP e alturas comercial e total, idade dos indiv??duos e Incremento M??dio Anual-IMA). Caracter??sticas ed??ficas do solo (20 cm de profundidade) foram obtidas no entorno de cada ??rvore. Em seguida, realizou-se uma an??lise descritiva com as vari??veis observadas. Ap??s, foi aplicada a An??lise de Componentes Principais (ACP) das vari??veis do solo, objetivando selecionar as vari??veis mais importantes e reduzir o n??mero de vari??veis. An??lise de correla????o de Pearson foi realizada com as vari??veis de solos selecionadas e as vari??veis dendrom??tricas e de produ????o de ??leo. Nova ACP foi realizada, incluindo as vari??veis de solos selecionadas, as dendrom??tricas e produ????o de oleorresina. Com o intuito de se conhecer como as copaibeiras se assemelham em rela????o a todas as vari??veis medidas, foi realizada uma an??lise de agrupamento hier??rquico aglomerativo, utilizando a dist??ncia euclidiana e o m??todo de agrupamento de Ward. Os resultados indicaram que as 14 ??rvores analisadas produziram ??leo, com produ????o m??dia de 226,79 ml ?? 126,91 (95% IC, n=14). As vari??veis mais significantes neste estudo foram a Idade, IMA (Incremento M??dio Anual), Areia grossa, Altura Total e Quantidade de ??leo, nesta ordem. A idade m??dia das ??rvores de C. multijuga, foi de 100,36 anos ?? 11,88 e foi observada baixa correla????o entre a idade e produ????o de ??leo. Foi observado tamb??m que quanto maior a idade das ??rvores maior o DAP. A quantidade de ??leo mostrou estar correlacionada negativamente com o teor de mangan??s no solo, apesar da concentra????o de Mn n??o estar al??m dos limites toler??veis pelas plantas, n??o representando risco de toxidade. No contexto geral das vari??veis analisadas, a Idade, Incremento M??dio Anual, areia grossa, argila e quantidade de ??leo responderam por aproximadamente 84% da variabilidade do conjunto de dados analisado. A an??lise de agrupamento, no contexto de todas as vari??veis, evidenciou a forma????o de tr??s grupos, onde a dist??ncia geogr??fica entre os indiv??duos observa-se n??o ter influenciado o agrupamento destes, do ponto de vista de similaridade bi??tica e abi??ticas medidas. H?? que se destacar que de modo geral observou-se uma plasticidade das copaibeiras em ocorrer nas diversas concentra????es das vari??veis analisadas, o que sugere que esta esp??cie possui adaptabilidade para diferentes condi????es de solo, e que estudos adicionais devem ser realizados com um n??mero maior de amostras para corroborar tais observa????es.
