Comparison of physical properties of White Poplar and clone ˈVillafrancaˈ wood

Differences between plantantion grown and natural poplars are a subject of limited number of investigations. Acquiring genotypes of forest trees with properties better than the existing is the main aim of the breeding application. Another important goal is the increase in wood quality. In this article, preliminary results on physical properties of white poplar and clone 'Villafranca' wood are presented. Five representative trees of both origin were collected. The site is located near the city of Varaždin in Republic of Croatia, within Varaždin Podravina forests. The investigations were carried out using segments with north and south orientation in the wood at the breast height of each tree. The results of average values indicate there is a significant difference in wood density, longitudinal, tangential, radial and volume shrinkage and maximal moisture content between white poplar and clone 'Villafranca' wood. For a better prediction of white poplar and clone 'Villafranca' wood quality further research on mechanical properties is needed.
