Wood density as an integrating variable of wood anatomy: Analysis of branches and stem in four species of Eucalyptus
Keywords:
cell morphometry, wood density, percentage of tissues, vessels, fibersAbstract
The aim of this study was to determine the relationship between wood density and xylem anatomy of branches and stem of four commercial Eucalyptus L´Hér. (Myrtaceae) species, considering anatomy as the main determinant of xylem functionality. We worked with samples from branches (n = 30) and stem (n = 82) of four species of adult’s trees: E. grandis, E. camaldulensis, E. viminalis and E. globulus. The wood density and quantitative anatomical features of vessels, fibers and proportion of tissue (fibers, vasicentric tracheids, vessels, rays and parenchyma) in histological sections and macerated were determined in both organ types (stem and branches). The wood density of stem was different among species but it was similar in the branches. According to the relationships found between density and anatomy, using correlations and principal component analysis, trends not always followed similar patterns among branches and stem. The wood density was not a good predictor of the several individual anatomical variables within each organ considered. In the case of branches, the density was revealed as an integrating variable of fraction lumens more than the individual variables of vessels (diameter or number) or the associated wall fractions (biometrics of fibers and occupied area). In contrast, in stem, density integrated fraction lumens (vessels), including morphometry of fibers and tissue percentages. Then, it is possible to find species / genotypes of similar density in this genus but with different composition / anatomical structure.
