“…3h). Pape (1999) found in Picea abies that the stands with the heaviest thinning showed the highest taper and the stands with natural thinning showed the lowest taper. After thinning, the remaining trees use the additional space to grow more in diameter and less in height, changing the growth pattern of trees (Zobel & Van Buijtenen 1989).…”

“…For instance, thinning artificially modifies the stand structure, opening the space for the remaining trees and increasing light, temperature, and air currents inside the canopy (Peltola et al 2007). As a general rule, the remaining trees grow more in diameter, developing larger crowns with bigger branches (Pape 1999, Gort et al 2010, but the extent of this pattern depends on the growth potential and the thinning intensity (Meneses & Velasco 1992). Pruning also has strong effects on tree structure, changing the photosynthetic capacity of the crown.…”

(5-6) Simultaneous applications of thinning and pruning are common silvicultural practices in radiata pine (Pinus radiata) forest plantations. Their separate effects on tree growth and wood quality have been well studied, but their combined effect is not clear yet. The aim of this study is to identify how thinning and pruning together affect the stem structure and properties of the pruned but also the unpruned section of the trees (the portions formed immediately after the application of these management efforts). The effects of pruning and thinning on the number of growth units per year, internode length, number of branches, and branch diameters was analyzed in managed and unmanaged stands of radiata pine grown in Chile. When used jointly, these practices generated larger individual tree volumes (135% more) and clear wood in the pruned logs; however, they also reduced the sawn wood quality of the unpruned stem section for some years after the silvicultural interventions. The managed trees showed more growth units per annual shoot and shorter internodes, thus generating more knotty wood. Moreover, managed trees showed more taper. As trees of the managed stand restore the foliar biomass lost due to pruning, managed and unmanaged stands approach the same level of canopy closure, and differences minimize.

“…Brolin et al 1995;Shupe et al 1996;Bergh et al 1999). Impacts on wood quality of such forest management techniques have, however, been questioned (Brolin et al 1995;Shupe et al 1996;Pape 1999) for several reasons. Fertilisation increases tracheid lumen diameter and decreases cell wall thickness, decreasing the basic density of wood (e.g.…”

Until now the pulp and paper industry has examined the chemical composition and fibre properties of raw material mainly after processing, while the biological aspects of wood formation have been considered less often.…”

The aim of the present study was to determine how long-term nutrient optimisation of Norway spruce stands affects the chemical composition of stem wood. Material for the study was collected from Flakaliden (Sweden) where Norway spruce [Picea abies (L.) Karst.] stands have been grown either without fertilisation or under nutrient optimisation treatment, by supplying a complete nutrient mix in the irrigation water every 2nd day during the growing season. The experiment was established in 1987 and in the autumn of 1998, 12 trees were harvested both in control (no fertilisation) and irrigated-fertilised (IL) stands. The increased growth rate caused by the IL treatment affected the chemical composition of the stem wood. The most pronounced effect was a 7% increase in lignin concentration caused by the IL treatment. Increases in concentrations of acid-soluble lignin (1.1-fold), extractives (1.2-fold), soluble sugars (1.3-fold), sterols (1.3-fold) and dehydroabietic acid (1.6-fold) as well as a decrease in the proportional quantity of terpinolene were also found. These results demonstrate that nutrient optimisation affected the chemical composition of Norway spruce wood, which may influence the suitability of such wood for specific end-use purposes.

“…In general, ARW depends on tree vigor, planting density, and environmental conditions (Pape 1999a, 1999b, Ishiguri et al 2005. Our results showed a decrease in the maximum ring width after the seventh year since plantation that could be related to crown closure, according to Ishiguri et al (2005).…”

Planting density is a major factor in determining tree growth and wood quality. Although the effect of low planting density on the variation of tree and wood characteristics has been already reported, the effect of intensive initial densities in plantations has not been fully assessed yet. In this study, the effect of intensive planting densities on tree growth, wood density and fiber cell properties was investigated in the context of the development of densely-stocked maple plantations for wood production. The study was carried out in a 12-year-old Acer velutinum trial plantation in northern Iran, with initial densities of 10000, 4444, and 2500 trees ha -1 planted. The variation of diameter at breast height, annual ring width, stem taper, wood density, and fiber cell properties were examined. As expected, low planting densities showed trees with larger diameter at breast height and annual ring width. The largest trees at higher densities were smaller than those in lower planting densities. However, initial planting density had no significant effect on stem taper, wood density and fiber cell properties. In addition, no significant relationships between tree growth features and wood properties were detected, indicating similar wood properties at all planting densities. Therefore, stand/tree growth attributes under intensive planting densities could not be considered as reliable predictors of the wood properties.
