“…While highly ranked, the impact was more severe for E. globulus. The presence of these defects in the peeled veneer supports the findings of previous research studies, which have shown that these species may not heal well after pruning or self-pruning, with the section of stem-wood laid down post-prining being prone to decay entry and slow occlusion (Wardlaw and Neilson 1999;Pinkard 2002;Pinkard et al 2004;Deflorio et al 2007).…”

“…The presence of defects, including bark pockets and decay, which were mostly associated with knots, encased knots, surface roughness, and gum pockets in similar proportions across all sites, suggest that at the Deans Marsh site the pruning had not been effective in allowing clear wood to be produced. This may be due to suboptimal pruning techniques, timing and procedures, and/or may be a physiological characteristic of this species (Wardlaw and Neilson 1999;Pinkard 2002;Pinkard et al 2004;O'Hara 2007;Deflorio et al 2007). An additional influence may be the below average rainfall (665 mm in 2004, 709 mm in 2005, and 474 mm in 2006 recorded at the site compared with a 852 mm long-term average) the Deans Marsh site received for the three years following the last pruning.…”

The processing of Australian plantation-grown Eucalyptus globulus and E. nitens into rotary veneer was shown to produce acceptable recoveries. Three plantation sites for each species were sampled. Silvicultural treatments (thinning and pruning) and growing environments varied between sites. Graded veneer recoveries were dominated by Dgrade veneer across all six sites. Variation between the E. nitens sites was evident, with recoveries differing between sites reflecting silvicultural treatments. However, only minimal variation in recovery was shown between the E. globulus sites. The presence of similar levels of defects across all E. globulus sites indicates that the intensive silvicultural management at one site studied was not effective in the production of clear wood, and may possibly have adversely affected grade recovery. Veneer value analysis demonstrated only minimal differences between E. globulus sites. More variation was observed in the E. nitens value analysis; however, intensive silvicultural management implemented did not necessarily result in higher veneer value.

“…Pinkard (2003) recomendou remoção de até 20% de área foliar em sítios pobres e até 40% em sítios mais produtivos. Porém, deve-se levar em conta, também, a capacidade de recuperação e crescimento da copa, o que influencia o posterior crescimento do tronco das plantas (PINKARD, 2002;LIMA, 2003;PULRONIK et al, 2005).…”

Cerrado, no espaçamento inicial de 3 x 3 m, foram submetidas à desrama artificial e ao desbaste. Os tratamentos de desrama tiveram início em três idades diferentes: 16, 20 ou 28 meses. Foram utilizadas três a quatro intervenções de desrama, com remoção de copa em diferentes alturas, para atingir 6 m de fuste livre de nó, quando se iniciou a desrama aos 16 ou 20 meses, e duas a três intervenções, quando se iniciou aos 28 meses. Foram aplicados dois tratamentos de desbaste aos 55 meses, com remoção de 0 e 35% do número de mudas plantadas. O crescimento foi avaliado no período pós-desbaste, entre 55 e 93 meses de idade, por meio da análise do diâmetro (DAP), altura total (Ht), volume com casca (V), incremento periódico anual pós-desbaste (IPA) e incremento médio anual (IMA). Aos 93 meses, não foram observadas diferenças significativas (p>0,05) em DAP, Ht, V, IPA e IMA, entre os tratamentos de desrama, e na interação entre desrama e desbaste. No tratamento desramado até 1,5 m de altura, aos 16 meses, houve remoção de 80% da biomassa de folhas e galhos. Nesse tratamento, 65% dos indivíduos estavam com DAP inferior a 15 cm, em comparação com 35% nos demais tratamentos. A Ht no povoamento desbastado foi menor (p≤0,05) do que no não desbastado. O V, o IPA e o IMA foram, respectivamente, de 7,9, 23,0 e 7,3% mais elevados (p≤0,05) no povoamento desbastado, quando a primeira intervenção de desrama foi aplicada aos 20 meses. O povoamento não desbastado teve crescimento estagnado aos 80 meses. No desbastado, essa estagnação deverá ocorrer entre 100 e 110 meses de idade, indicando necessidade de aplicação do segundo desbaste nessa faixa etária, para obtenção de toras de maior diâmetro e, consequentemente, maior extensão de madeira limpa.Palavras-chave: Crescimento de plantas, desbaste e desrama artificial.

“…Higher initial stocking densities reduce the incidence of large branches (Neilsen and Gerrand 1999) but may lead to a reduction in the average growth of individual trees. Unlike lift pruning, form pruning selectively removes branches throughout the crown and can be used to reduce average branch size before subsequent lift pruning (Pinkard 2002). It can also be used to correct potential deviation of stems from a pathway of vertical growth (Nicholas andGifford 1995, Medhurst et al 2003).…”
