| Abstract: | Summary Relationships between various anatomical parameters and selected physico-mechanical properties of wood were examined statistically in East-Liaoning Oak. Path analysis revealed that the key anatomical factors influencing wood shrinkage vary with the type of shrinkage: both radial and tangential shrinkage are mainly controlled by fiber diameter, differential shrinkage mainly by microfibrillar angle and volumetric shrinkage by tissue proportions; specific gravity is determined directly by percentage of cell wall material, while the percentage, in turn, is closely related to tissue proportions, among which vessel proportion is the most important; tensile strength is closely related to microfibrillar angle and specific gravity is not always a good estimator of strength.We to express our sincere thanks to Prof. B. F. Ke and Prof. Dr. P. Baas for their support and help. The paper is based mainly on the presentation at the Timber Engineering Meeting, Saint John, Canada, July 30–August 4, 1990. |
