“…In 12-year-old Tectona grandis trees planted in Indonesia, significant differences in growth characteristics (D, TH, and stem volume) and the SWV were observed among 15 clones (Hidayati et al 2013). Our results for D, TH, and SWV are consistent with those obtained by previous studies on Z. serrata and other hardwood species (Endo et al 1998;Wu et al 2011;Hidayati et al 2013). Fig.…”

“…In a previous study, significant differences in D and TH were observed in 4-year-old Z. serrata trees planted at the same site of the present study (Endo et al 1998). Among-family variation or clonal variation in growth characteristics and wood quality have been reported in other hardwood species (Wu et al 2011;Hidayati et al 2013). Wu et al (2011) reported that significant differences in D, TH, and SWV were found among 19 Eucalyptus hybrid clones planted in southern China.…”

“…For example, Hidayati et al (2013) reported that the repeatability of the SWV in 12-year-old T. grandis trees from 15 clones was 0.27. In addition, Wu et al (2011) reported that the repeatability value of SWV in Eucalyptus hybrid clones was 0.77. Our results for the repeatability of D, TH, and SWV are in the range of those obtained by other researchers (Volker et al 1990;Hai et al 2008;Wu et al 2011;Hidayati et al 2013).…”

Zelkova serrata is an important hardwood species for the timber industry in Japan. Tree breeding programs for this species have mainly focused on growth characteristics such as stem diameter (D), tree height (TH), stem form, and branching. In order to fulfill timber industry needs, wood quality improvement should be included in the tree breeding program of this species. In the present study, growth characteristics, such as D and TH, and the stress-wave velocity (SWV), which is highly correlated with Young's modulus of wood, were measured for 20-year-old Z. serrata from eight half-sib families planted in a progeny test site with three different initial spacings. Significant differences in all the measured characteristics were found among the eight half-sib families. The variance components of the half-sib families for D, TH, and SWV were 27.2%, 47.3%, and 33.5%, respectively. These results indicate that all the measured characteristics of this species could be improved by tree breeding programs. In addition, only low correlation coefficients were obtained between the growth characteristics and SWV, indicating that extensive selection on SWV in tree breeding programs may not always lead to a reduction in yield volume.

“…Entre os caracteres da madeira, são abordados tópicos relacionados à produtividade de madeira sólida, rendimento de polpação e densidade básica (HEIN et al, 2012;KIEN et al, 2010;STACKPOLE et al, 2010;WEI;BORRALHO, 1997;WENG et al, 2014;WU et al, 2013), sendo que a última foi eleita como uma das propriedades mais importantes na caracterização tecnológica (WU et al, 2011) e fundamental na determinação do poder calorífico, qualidade da polpa celulósica e na definição de aplicações estruturais (KIEN et al, 2009a;LOPES et al, 2011;PEREIRA et al, 2012).…”

ResumoA produção volumétrica tem sido prioridade nos programas de melhoramento florestal. No entanto, é necessário que a qualidade da madeira seja considerada, para que o fornecimento da matéria prima permita aumentar a eficiência e o rendimento industrial. Dessa forma, o objetivo deste trabalho foi estimar parâ-metros genéticos, correlações genéticas e ganhos com a seleção para caracteres de crescimento (diâme-tro), espessura de casca e densidade básica da madeira de Eucalyptus urophylla. Para tanto, utilizou-se discos de madeira retirados no DAP e metade da altura comercial, provenientes de árvores desbastadas em um teste de progênies de polinização aberta com 33 genótipos e duas procedências (Rio Claro-SP e Três Lagoas-MS), localizado em Selvíria-MS. Os parâmetros genéticos foram obtidos com base no procedimento REML/BLUP. O melhor desempenho para crescimento foi verificado para Rio Claro. Não foram detectadas diferenças genéticas para densidade da madeira entre as procedências. A procedência de Três Lagoas apresentou coeficiente de variação genética > 14% (diâmetro) e forte controle genético (herdabilidade > 0,6 e acurácia > 78%). Para qualidade da madeira, Rio Claro sobressaiu-se nas estimativas de herdabilidade (> 0,6 -DBM e ECD), alcançando acurácia superior a 79%. Foram encontrados resultados contrastantes para as correlações genéticas entre as duas procedências. Para a obtenção de materiais genéticos com maior densidade da madeira, a seleção para DBM é vantajosa. Palavras-chave: melhoramento florestal, qualidade da madeira, REML/BLUP. AbstractVolumetric production has been a priority in forest breeding programs. However, it is necessary to consider wood quality for the raw material supply that increases efficiency and yield. Thus, the aim of this study was to estimate genetic parameters, genitic correlations and selection gains for growth traits (diameter), bark thickness and basic density of wood in progênies of Eucalyptus urophylla. For this, we used wood discs removed at DHB and half the commercial height, from trees thinned in an open pollination progeny with 33 genotypes and two provenances (Rio Claro-SP and Três Lagoas-MS), located in Selvíria-MS. Estimates of genetic parameters were obtained using the REML/BLUP method. The best performance for growth was found in the Rio Claro provenance. Genetic differences in wood density between the provenances were not detected. The provenance of Três Lagoas showed a coefficient of genetic variation > 14% (diameter) and strong genetic control (heritability > 0.6 and accuracy > 78%). For wood quality, Rio Claro stood out in the estimates of heritability (> 0.6 -DBM and ECD), achieving a higher accuracy of 79%. Contrasting results were found for the genetic correlation between the two sources. For obtaining genetic materials with higher density wood, the selection for DBM is advantageous.
