Ensaio de espaçamento com Caroba - Jacaranda copaia (Aubl.) D. Don. Bignontaceae

In 1980, an experiment with Caroba (Jacaranda copaia (Aubl.) Dan) was placed in the Experimental Sation of Tropical Silviculture at INPA, Manaus for testing three different plant spacing (2,0 x 3,0 m; 3,0 x 4,0 m and 4,5 x 4,0m). in 1989, the results showed that the estimate of total survival of pla...

Fifth year after planting, in 1985 it was observed that in all the experiment a significant number of trees showed a chlorotic canopy, with falling leaves, as a consequence, an increase of dead trees was obsrved, perhaps because of soite nutritional constraint the occurred in this experiment. Na Estação Experimental de Silvicultura Tropical (E.E.S.T.) do INPA-Manaus, foi instalado no ano de 1980 um experimento para Caroba em três (3) espaçamentos. As avaliações da sobrevivência, altura total e comercial, D.A.P., área basal e volume realizadas no ano de 1989, nove anos após o plantio, indicaram que o menor espaçamento (2,0 X 3,0 m) apresentou maior volume de madeira útil em função do grande número de árvores vivas (70,98%) com altura comercial média de (11,76 m) e D.A.P. médio aritmético de 22,73 cm. Após o 5º ano de plantio, foi observado que um número significativo de árvores apresentaram copas cloróticas, seguida da queda das folhas e consequente morte das árvores, fato este, possivelmente relacionado com o estado nutricional das árvores deste experimento. 2020-04-24T16:30:53Z 2020-04-24T16:30:53Z 1989 Artigo https://repositorio.inpa.gov.br/handle/1/14253 10.1590/1809-43921989191389 pt_BR Volume 19, Pags. 383-389 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
