Efecto de intensidades de poda en el crecimiento dasometrico de Gmelina arborea roxb de la empresa Arboriente S.A, en el cantón Loreto.

Abstract

This research aimed to evaluate the effect of different pruning intensities on the growth of the Melina tree species (Gmelina arborea Roxb) in the company ARBORIENTE S.A, located in Loreto town. Three study areas with different planting densities were established: 3.4 m x 3.4 m, 3 m x 3 m, and 2 m x 2 m. Each density was divided into three treatments with three repetitions, using pruning intensities of 25 %, 50 %, and 75 %. Throughout the study, six monthly evaluations were carried out to measure the diameter at plant neck height (DAC), diameter at breast height (DBH), and size. The experimental design used was Completely Random Blocks (DBCA). The collected data was submitted for statistical analysis using the Infostat software, where parametric and non-parametric tests were applied. The results revealed significant differences in evaluations 2 and 4 concerning diameter, while no significant differences were observed in height in evaluation 6. When analyzing the best pruning intensity, it was determined that the treatment of 50 % in the 3.4 m x 3.4 m density promoted higher growth of Gmelina arborea Roxb. In conclusion, the findings support the alternative hypothesis, evidencing that at least one of the pruning intensities evaluated positively affected the development of Gmelina arborea. These conclusions are relevant to guide the future use of the wood obtained.
