Normal and tension wood had similar basic densities; while for opposite wood, the density was lower, being responsible for a decrease in reaction wood density.

The chemical composition of the wood was influenced by the presence of reaction wood in the stem. Tension and opposite wood showed lower levels of extractives and lignin and higher holocellulose content when compared to normal wood, with favorable wood quality for pulping. The increase in holocellulose content and the reduction of lignin and extractives content contributed positively to a more delignified pulp and reduction of the Kappa number. However, after cooking the reaction wood under the same conditions as those of normal wood, reaction wood pulping tends to have a lower screen yields.

Due to differences in basic density and chemical constituents between opposite and normal wood, it is recommended not to designate the opposite wood as normal wood. Wood from fast-growing forest species, such as eucalyptus clonal hybrids for the pulp industry, is the main driver for the improved performance of the forestry plantation sector in Brazil. However, young trees with very tall stems have high slenderness indexes and are more vulnerable to wind action, which is a natural and uncontrollable factor.

Such occurrences in commercial plantations can create stress on the trees, and in more dramatic scenarios, strong winds can cause damage, such as the tilting of the stem at different angles in trees of a single plantation and in trees with ages below the rotation cycle for cutting.

Reaction wood is induced in inclined stems in an effort to return the tree to its vertical axis through symmetry biomechanics. Reaction Wood.

Shrinkage of the gelatinous layer of poplar and beech tension wood. IAWA Journal, v. Relationship between transverse shrinkage and tension wood from three provenances of Eucalyptus globulus Labill.

Holz als Roh- und Werkstoff. Characterization of tension wood in Eucalyptus grandis and evaluation of its effect on kraft pulp production. As for the reaction wood formed on the opposite side to the tilting, it carried little importance, due to the result of the suppressed growth on this side of the stem.

Determination of differences in anatomical and chemical caharacteristics of tension and opposite wood of 8-Year old Eucalyptus Globulus. O Papel, v. The divergence of the reaction wood properties compared to normal wood in eucalyptus forest plantations influences its quality, and depending on the intensity of the affected population, the manufacturing process in the pulping industry must be modified for better results.

Unusual tension wood characteristics may significantly impact bleached pulp production, but little is currently known about it as it relates to eucalypt trees grown in tropical regions. A study carried out with Eucalyptus globulus wood showed that kraft pulps derived from reaction wood present lower yields and a higher kappa number in relation to opposite wood, for a given effective alkali charge AGUAYO et al. Chemical characteristics and Kraft pulping of tension wood fromEucalyptus globuluslabill.

The high cellulose content in Populus tristis tension wood was proven desirable for pulp yield and pulp brightness. Tension wood anatomy of short rotation Populus spp. Wood Science, v. Verifying the pulping parameters is essential to ascertain the quality of the wood from forest plantations. Determining the density and chemical characterization of wood is essential to explain the behavior of the wood before pulping parameters, especially when it comes to little studied matters, as is the case of reaction wood on the tension and opposite side.

This study aims to evaluate the quality of normal, tension and opposite wood of eucalyptus trees lengthwise, in straight and inclined stems, affected by the action of winds, as well as to explain the pulping parameters due to the quality of the wood. The wood used was from commercial forest plantations of Eucalyptus grandis x Eucalyptus urophylla clones from Ipaba municipality, located in the region of the Vale do Rio Doce, east of Minas Gerais. The trees were planted in February on flat ground with a spacing of 3.

The area was struck by heavy winds in November , 33 months after planting, reaching speeds of up to 72 km. The cutting procedure took place in January , 38 months after the occurrence of the winds in the plot, and 71 months after the date of planting.

Twenty 20 trees were randomly selected and separated into groups according to the tilt angle. From Group 1, we obtained normal wood from trees possessing a straight stem, i. The division of trees per tilt group allowed a better assessment of the characteristics of the wood in the trees inclined with different bottom-up lengths and mainly in the area in which a consolidated arrow by wind actions was formed.

Dendrometric parameters and eccentricity of the pith in leaning eucalypt trees. Scientia Forestalis, v. Five trees were collected for each tilt category. In each position, 3. Wedges were removed from the discs of trees with an inclined stem to sample the sides above and below the incline, respectively, tension and opposite wood. In positions O Papel , v. Ultraviolet spectra.
