Wood density and tracheid length of Aleppo pine (Pinus halepensis Mill.) grafts in relation to cambium age and growth rate

open access: yesJournal of Forest Science, 2018
Wood density, tracheid length and growth rate were measured in Aleppo pine scions, 21-23 years old, and in Brutia pine rootstocks. In regard to the relationship between cambial age and dry density the results showed that the density increased with ...

Effect of the position in a stem on the length of tracheids in spruce (Picea abies [L.] Karst.) with the occurrence of reaction wood

open access: yesJournal of Forest Science, 2005
The paper was aimed at the determination of variability of tracheid dimensions in spruce wood in relation to the position in a spruce stem. Significant changes in dimensions were found in early-wood and late-wood tracheids along the stem length and ...

Assessment of wood microstructural changes after one-stage thermo-hydro treatment (THT) by micro X-ray computed tomography [PDF]

open access: yes, 2015
The microstructural changes in a selection of softwoods and hardwoods resulting from thermo-hydro treatment (THT) at 160°C were examined by means of a state-of-the-art micro X-ray computed tomography.

Microstructure of chemically modified wood using X-ray computed tomography in relation to wetting properties [PDF]

open access: yes, 2016
X-ray computed tomography (XCT) was utilized to visualize and quantify the 2D and 3D microstructure of acetylated southern yellow pine (pine) and maple, as well as furfurylated pine samples. The total porosity and the porosity of different cell types, as

Radial Variation in Selected Physical and Anatomical Properties Within and Between Trees of 31 Year Old Pinus caribaea (Morelet) Grown in Plantation in Nigeria

open access: yesSouth-East European Forestry, 2016
Background and Purpose: Variation in wood is a common phenomenon. Eliciting information on the pattern and extent of variation in wood properties is crucial to knowing the end use of wood species.

Length, diameter and cell wall thickness of tracheids in mature lodgepole pine bole wood

open access: yesSilva Fennica, 1985
Variation in tracheid morphology were examined for the bole wood of lodgepole pine ( Douglas ex Loudon) grown in Southern and Central Finland. Tracheid lengths were examined in a fast-grown and in slow-grown trees from three stands.
