“…The genetic and phenotypic coefficients of variation values for wood density in the present study were lower than the values reported by Pliura et al (2007). However, our study showed lower difference between the genotypic (5.36) and phenotypic (7.41) coefficients of variation.…”

“…The heritability for wood density was 0.72, which is comparable to or higher than previous results. Heritability for wood density of Populus clones was reported at 0.51 by Peszlen (1998), and at 0.35 by Yanchuk et al (1983) for Populus tremuloides, and at 0.69 by Farmer and Wilcox (1968) and Beaudoin et al (1992) for P. euramericana clones, and at 0.22 to 0.52 by Pliura et al (2007) for hybrid poplar clones. The reasons for high heritability for wood density could be related to a lower contribution for nonadditive genetic variance and substantial genome by environment (G x E) interactions (Saifullah and Rabbani 2009).…”

“…Hybrid poplars have been genetically improved through selection and crossbreeding to improve growth rate, trunk form, adaptability, and disease resistance (Hernández et al 1998;Riemenschneider et al 2001;Zhang et al 2003;Pliura et al 2007).…”

“…The Saint-Ours site is located in the Champlain marine deposit, where the soil consists of a silty clay deposit with 40% clay (Table 2). The two other sites consist of sandy loam soil (Pliura et al 2007). The Windsor site is located in a slightly more elevated geographical area with cooler climatic conditions.…”

The physical and mechanical properties of poplar clones largely determine their suitability for various end-uses, especially for high valueadded applications. The main objective of this study was to determine the clonal variation of selected physical and mechanical properties of seven hybrid poplar clones grown at three sites in southern Quebec, Canada. Five trees per clone were randomly sampled from each site for wood properties measurement. Site had a significant effect on all measured properties except radial shrinkage. All properties of hybrid poplar wood showed significant interclonal variation, indicating the possibility of identifying clones with superior wood properties, especially for density, flexural modulus of rupture, and ultimate crushing strength. High heritability values for the studied properties indicated that these properties are under moderate to high genetic control. The genetic gain for these wood properties ranged from 2.0% to 13.5%.

“…Density, for example, shows high heritability and responds well to genetic improvement (Zobel and Jett 1995). It was confirmed in another work by Pliura et al (2007), where wood density of poplar hybrids was under strong genetic control. Heritability and additive genetic coefficient of variation within seven traits of forest trees were compiled by Cornelius (1994) on the basis of 67 published papers.…”

Differences in wood properties of Picea abies L. Karst. in relation to site of provenance and population genetics Abstract: Chemical and physical characteristics of wood from six European populations of Picea abies were investigated taking into consideration their genetic differentiation determined by four microsatellites markers. The growth conditions of investigated spruce trees differed significantly. As a consequence, several adaptations were observed in samples from varying environments. The adaptation mechanisms include a variation to the annual rings morphology as well as the physical properties of the wood. It was proved that some properties, such as wood density or latewood ratio, are strictly correlated to the environmental variables. Results show that trees from geographically distinct populations present some diversity in the genotypes. It was also noticed that some trees did not share their genetic profile with other plants from the same location due to high intrapopulation variability. Samples from Finland possessed the lowest level of internal differentiation, while samples from northern Poland presented the lowest allele richness and were most divergent from the others. It was not possible to correlate any wood properties (chemical or physical) to genetic features of the population due to high intrapopulation diversity.
