Variation in wood density between mature sessile oak and English oak trees growing in different vegetation zones

Popis výsledku v původním jazyce

Wood density is a fundamental functional trait influencing ecological adaptation, hydraulic safety, and timbernutilisation in temperate hardwoods. This study investigated variation in wood density (12% moisture) across maturenstands of two economically and ecologically vital European oak species, sessile oak [Quercus petraea (Matt.) Liebl.] andnEnglish oak (Quercus robur L.), growing in their characteristic vegetation zones in the Czech Republic. We assessednwood density at two heights (at 1.3 m and at the crown base) across six trees per plot and examined its relationship withntree-ring width and height. Results demonstrated statistically significant interspecific differences, with Q. petraea con-nsistently exhibiting higher wood density (721 kg·m−3) than Q. robur (662 kg·m−3) at 1.3 m. Q. petraea showed a statisti-ncally nonsignificant higher density of 710 kg·m−3 at the crown base and an overall average of 717 kg·m−3, while Q. roburnhad densities of 701 kg·m−3 and 669 kg·m−3, respectively. Radial density profiles revealed species-specific patterns, withnQ. robur showing a more uniform density distribution than the pronounced pith-to-bark gradients observed in Q. pe-ntraea. Regression analysis indicated that tree-ring width explained only 12–13% of the variance in density, so othernanatomical factors, such as latewood proportion and tree-ring structure (number and cell size), should be examinednas anatomical drivers of wood-density variation.
