Resumo: | The present study evaluated the dendrometric, chemical and basic density wood from five hybrids of Eucalyptus grandis x Eucalyptus urophylla at 2.25 years old. The experiment was implemented in 3.5 x 2 meters spacing, with 35 replicates of a single tree. Four replicates were harvester, we evaluated the diameter at breast height (DBH, 1.3 m above the ground), total and commercial height, biomass of leaves, branches, wood and bark, volume with and no bark and volume of bark. Besides it was obtained discs at 0, 25, 50, 75 e 100% of commercial height and at DBH for the determination of wood density and chemical characterization of wood. Data were subjected to analysis of variance and comparison of means by Tukey's test at 5 % probability. Clones of Eucalyptus grandis x Eucalyptus urophylla exhibited different growth highlighting the C5 with greater volumetric and biomass. The basic density wood is higher when assessed at base of tree, but it was verified similar values in other positions of the stem. Among the clones, the basic density wood of C5 is higher than C3 and C4 and C2 is higher than C3. The chemicals wood characteristics were similar among clones of Eucalyptus grandis x Eucalyptus urophylla. Despite the evaluation have been performed on young plants, 2.25 years old, the clones have demonstrated satisfactory potential in Jaboticabal, SP. |

O experimento foi implantando no espaçamento 3,5 x 2 m, com 35 repetições e parcelas de uma planta. Quatro repetições do experimento foram cortadas avaliando-se o diâmetro a altura do peito (DAP, a 1,3 m do solo), altura total e comercial, biomassa seca de folhas, galhos, madeira e casca, volume com e sem casca e volume de casca. Das árvores abatidas foram retirados discos de 5 cm de espessura no DAP e a 0 (base), 25, 50, 75 e 100% da altura comercial, para determinação da densidade básica e caracterização química da madeira. Os dados foram submetidos à análise de variância e comparação de médias pelo teste de Tukey a 5% de probabilidade. Os clones de Eucalyptus grandis x Eucalyptus urophylla diferiram quanto ao volume e biomassa com destaque para o C5 com valores superiores aos demais clones. A densidade básica da madeira foi maior na base da árvore; nas demais posições de amostragem, os valores de densidade foram semelhantes entre si; dentre os clones, o C5 apresentou densidade básica da madeira superior ao C3 e ao C4, assim como o C2 superou o C3. As características químicas da madeira foram semelhantes entre os clones e, apesar da avaliação ter sido realizada em plantas jovens, os clones demonstraram bom potencial em Jaboticabal - SP.Universidade Estadual Paulista Faculdade de Ciências Agrárias e VeterináriasFaculdade de Tecnologia de JaboticabalUniversidade Estadual Paulista Faculdade de Ciências Agrárias e VeterináriasUniversidade Federal de Santa MariaUniversidade Estadual Paulista (Unesp)Faculdade de Tecnologia de JaboticabalHsing, Tseng YaoPaula, Nadia Figueiredo DePaula, Rinaldo César De2018-11-12T17:29:02Z2018-11-12T17:29:02Z2016-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article273-283application/pdfhttp://dx.doi.org/10.5902/1980509821119Ciência Florestal.
