“…The other critical information necessary to assess the impact of pruning on veneer grading is the branch occlusion thickness before the tree produces wood free of knots and knot-related defects. According to the studies performed by Montagu et al (2003), Pinkard et al (2004), Smith et al (2006), O'Hara (2007), Liu et al (2012), and Forrester et al (2013), the occlusion thickness can be estimated depending on the type of species. For the fast-growing pulp species in this study (E. dunnii and E. globulus), the occlusion thickness is on average 2 cm.…”

aProcessing Australian hardwood plantations into rotary veneer can produce more acceptable marketable product recoveries compared to traditional processing techniques (e.g. sawmilling). Veneers resulting from processing trials from six commercially important Australian hardwood species were dominated by D-grade veneer. Defects such as encased knots, gum pockets, gum veins, surface roughness, splits, bark pockets, and decay impacted the final assigned grade. Four grading scenarios were adopted. The first included a change to the grade limitations for gum pockets and gum veins, while the second investigated the potential impact of effective pruning on grade recovery. Although both scenarios individually had a positive impact on achieving higher face grade veneer qualities, the third and fourth scenarios, which combined both, had a substantial impact, with relative veneer values increasing up to 18.2% using conservative calculations (scenario three) or up to 22.6% (scenario four) where some of the upgraded veneers were further upgraded to A-grade, which attracts superior value. The total change in veneer value was found to depend on the average billet diameter unless defects other than those relating to the scenarios (gum or knots) restricted the benefit of pruning and gum upgrading. This was the case for species prone to high levels of growth stress and related defects.

“…Esses mecanismos se realizam mediante reações químicas que criam barreiras, impedindo a entrada de fungos e outros patógenos (Schwarze et al, 2000;Ferreira & Milani, 2002). A redução do crescimento, depois de uma desrama forte, pode afetar o tempo de oclusão dos ferimentos, que resulta em aumento do risco de invasão por patógenos e perda da dominância, ocasionando desvantagem na competição por luz em um povoamento florestal (Montagu et al, 2003).…”

“…Por sua vez, fatores de estresse, como o deficit hídrico, podem contribuir para a predisposição a doenças relacionadas ao processo de declínio (Manion, 2003). Outro aspecto a ser considerado é a velocidade da oclusão de ferimentos, influenciada pelo diâmetro dos ramos e vigor vegetativo (Schwarze et al, 2000;Montagu et al, 2003).…”

Resumo -A desrama é um procedimento que aumenta o valor e a qualidade da madeira. Entretanto, se realizada de forma inadequada pode reduzir o crescimento e constituir fator de predisposição à podridão-do-lenho. O objetivo deste trabalho foi estudar o efeito da intensidade e época da desrama sobre o crescimento inicial e incidência de árvores com ferimentos não cicatrizados de Acacia mangium. Foi instalado um experimento em delineamento de blocos ao acaso, com três repetições e cinco tratamentos: testemunha (sem desrama); desrama de troncos múltiplos e galhos a 50 e 70% da altura, em época de baixa e alta pluviosidade. As avaliações de crescimento e presença de ferimentos não cicatrizados foram feitas seis meses depois da aplicação dos tratamentos. A época e a intensidade de desrama, quando efetuadas aos 8 e 13 meses, não afetaram o crescimento em diâmetro e altura. Houve boa cicatrização de ferimentos em árvores desramadas oito meses depois do plantio, em época de baixa pluviosidade, independentemente da intensidade. Árvores desramadas aos 13 meses depois do plantio, em época de alta pluviosidade, demonstraram predisposição à podridão-do-lenho.Termos para indexação: Racosperma mangium, diâmetro, altura, doença, manejo florestal. Pruning on growth and heartrot predisposing in Acacia mangiumAbstract -Pruning increases quality and economic value of the wood. Inadequate pruning procedures, however, interfere negatively on growth and consist on a predisposing factor to heartrot. The objective of this work was to investigate the effect of intensity and season of pruning on initial growth and on incidence of Acacia mangium trees with non-occluded wounds. The experimental design was in randomized blocks with three replicates and five treatments: control (without pruning); pruning and singling at 50 and 70% of total height, in low and high precipitation season. Growth evaluations and the presence of non-occluded wounds were performed six months after treatments application. The season and intensity of pruning operations did not influence height and diameter growth. Efficient wound occlusion occurred in trees pruned eight months after planting in low precipitation season, with no intensity effect. On trees pruned 13 months after planting, in high precipitation season, trees predisposed to heartrot were observed.
