“…This could be mainly due to the limited number of parents in the experiment and possible random genetic drift in the sampling [4]. The laboratory measurements techniques may need improvement for more reliable estimate of micro wood traits [17]. The results reported in this study should be considered cautiously and may be repeated with greater sampling size of parents.…”

“…Each sample was oven-dried for 12 h [14]. Chemical analysis of α-cellulose and lignin content, fiber length and coarseness was done using microanalytical techniques developed by Yokoyama et al [17], which allows the rapid characterization of fiber components and morphology of loblolly pine in a large number of samples. Briefly, the techniques involved are removal of extractives, holo-cellulose preparation, α-cellulose and lignin content determination, and average fiber length and coarseness analyses.…”

-Genetic variation and genotype by environment interaction (G×E) were studied in several juvenile wood traits of 11 year-old loblolly pine trees (Pinus taeda L.). Wafer thin (200 µm) samples from juvenile (ring 3) and transition (ring 8) wood of 12 mm increment cores were analyzed. Transition wood had higher α-cellulose content (46.1%), longer fiber (1.98 mm), and higher coarseness (0.34), but lower lignin (29.7%) than juvenile wood (cellulose 40.9%, fiber length 1.4 mm, coarseness 0.28 and lignin 30.3%). General combining ability variance for the traits explained 2% to 10% of the total variance, whereas the specific combining ability variance was negligible, except for α-cellulose content in transition wood (2%). Specific combining ability by site interaction variance explained from 5% (fiber length) to 37% (lignin) of the total variance. Weak individual-tree heritabilities were found for all the traits, except coarseness, which was moderately high in both juvenile (0.39) and transition wood (0.30). Full-sib and half-sib family heritabilities of traits ranged 0.29 to 0.72. Genetic correlations of wood quality traits with volume and stem straightness were weak, while favorable genetic correlations of lignin with cellulose, coarseness and fiber length were observed. Implications on forest tree improvement programs were discussed. heritability / genetic correlation / α-cellulose / coarseness / lignin Résumé -Variabilité génétique et stabilité génotype-environnement pour les propriétés chimiques du bois à un stade juvénile chez Pinus taeda L. La variabilité génétique et la stabilité génotype-environnement (G×E) ont été étudiées pour plusieurs caractéristiques du bois juvénile de pins taeda (Pinus taeda L.) âgés de 11 ans. De petits échantillons de bois de 2 mm d'épaisseur ont été extraits de carottes de sondage (12 mm), dans le bois juvénile (cerne 3) et dans la zone de transition (cerne 8). Le bois de transition a une teneur en α-cellulose plus élevée, des fibres plus longues (1,98 mm) et une grosseur de grain plus élevée (0,34) mais une teneur en lignine (29,7 %) plus faible que le bois juvénile (teneur en cellulose : 40,9 %, longueur des fibres : 1,4 mm, grosseur du grain : 0,28 et teneur en lignine : 30,3 %). La variance des aptitudes générales à la combinaison (AGC) explique entre 2 et 10 % de la variance totale, tandis que la variance des aptitudes spécifiques à la combinaison (ASC) est négligeable, excepté pour la teneur en α-cellulose dans la zone de transition (2 %). La variance de du terme d'interaction SCA-site explique de 5 % (longueur de fibres) à 37 % (teneur en lignine) de la variance totale. Les héritabilités au sens strict sont faibles pour tous les caractères sauf pour la grosseur du grain. Pour ce caractère, elle est modérément élevée dans le bois juvénile (0,39) et dans la zone de transition (0,30). Les héritabilités au niveau moyennes de familles de pleins-frères et de demi-frères varient de 0,29 à 0,72 pour ces caractères. Les corrélations génétiques entre propriétés du bois d'une par...

“…The amount of wood α-cellulose was quantified obtained from holocellulose preparations utilizing a procedure adapted from Yokoyama et al (2002). Holocellulose was prepared by weighing 250 mg of extractive free milled wood in a 50 mL round bottom flask and then adding 5 mL of deionised water, 2 mL of glacial acetic acid and 5 mL of 80% sodium chlorite.…”

Tension and opposite wood, divided in the corresponding heartwood and sapwood regions, from 8-year old Eucalyptus globulus trees were characterized for chemical composition and fibre anatomy in the transverse section in order to identify the main differences. Thicker and poorly lignified cell walls were found in tension wood. Cellulose content was similar for both woods, although tension wood contained 30% higher xylose and 15% less lignin than opposite wood. Lignin of tension wood contained 24% more syringyl units and a higher frequency of β-O-4 linkages. Principal component analysis (PCA) performed separately with anatomical and chemical data showed a clear separation between tension and opposite wood. The principal characteristics used for separation were: cell wall thickness, vessel diameter, lumen diameter, lignin and xylose content, and amount of syringyl units.

“…The solids were filtered; the sample was washed with 150 mL of distilled water and impregnated with 20 mL of 1 M CH 3 COOH for 5 min. The residue was washed with abundant distilled water and dried at 105°C until constant weight for the quantification of alpha-cellulose (Yokoyama et al 2002). Each sample was analyzed in triplicate.…”

Brachystegia spiciformis and Pericopsis angolensis are two hardwood species found in the Miombo woodlands. The wood features, kraft pulping and strength pulp properties of both species were evaluated in order to determine their potential as raw material for papermaking. Brachystegia spiciformis wood density was 640 kg m -3and Pericopsis angolensis was 795 kg m -3. Pericopsis angolensis wood has higher cell wall thickness and occluded fibre lumen as remarkable anatomical properties. Runkel ratio, slenderness ratio, and the coefficients of flexibility and rigidity in Brachystegia spiciformis were 1,5; 65,7; 41,2% and 29,4% while in Pericopsis angolensis these values were 17,6; 59,9; 5,4% and 47,3%, respectively. Brachystegia spiciformis has a higher cellulose content, lower hemicellulose and lignin content, and higher S/G ratio than Pericopsis angolensis. In kraft pulping, a higher demand of active alkali was needed for both species, and pulps with high kappa number (24-27) and low pulp yield (40%) were obtained. Pericopsis angolensis pulps reached tensile, tear and burst indexes of 99,6 Nm g -1 ; 5,9 mN.m 2 g -1 and 4,9 kPa.m 2 g -1 , respectively. Brachystegia spiciformis pulps reached tensile, tear and burst indexes of 100,3 Nm g -1 ; 10,7 mN.m 2 g -1 and 6,1 kPa.m 2 g -1 , respectively. As a conclusion, Brachystegia spiciformis wood has better pulpability than Pericopsis angolensis wood, according to its pulps properties, despite of the similar pulp yield between both species. Both species may be suitable for unbleached wrapping papers and rigid cardboards manufacturing.
