摘要

该研究调查了欧洲广泛分布的落叶乔木黑赤杨(Alnus glutinosa (L.) Gaertn.)的木材机械特性,因为它适合造林和木材工业应用。研究的目的是对选定的半同父异母科之间的这些特性进行比较,并评估木材硬度与其他特性之间的关系。1998 年,在不同的森林地区建立了立陶宛种群的黑赤杨后代实验种植园。研究分析了不同基因家族的各种参数,包括树木直径、高度、木材硬度、含水量、木材密度和机械性能。研究结果表明,半同父异母家族之间的木材特性存在很大差异,这突出表明了遗传因素的强大影响。虽然静态弹性模量在不同家系之间没有明显差异,但其他特性却存在显著差异。此外,分析还发现木材硬度与密度、弹性模量和弯曲强度等其他机械特性之间的相关性很弱。这表明,在工业应用中,木材硬度可能并不能可靠地表明木材的质量。因此,研究建议在未来的黑赤杨遗传研究中考虑采用动态弹性模量等其他非破坏性特性,以更准确地评估木材质量。

Variations in mechanical wood properties of half-sibling genetic families of black alder [Alnus glutinosa (L.) Gaertn.]
The study investigated the wood mechanical properties of black alder [Alnus glutinosa (L.) Gaertn.], a widely distributed deciduous tree in Europe valued for its suitability in silviculture and wood industry applications. The aim was to compare these properties among selected half-sib families and assess the relationship between wood hardness and other characteristics. Experimental plantations of black alder progenies from Lithuanian populations were established in different forest regions in 1998. The study analyzed various parameters for different genetic families, including tree diameter, height, wood hardness, moisture content, wood density, and mechanical properties. The findings revealed significant variability in wood properties among half-sib families, highlighting a strong genetic influence. Although the static modulus of elasticity showed no notable difference across families, other properties showed significant variations. Furthermore, the analysis identified weak correlations between wood hardness and other mechanical properties like density, modulus of elasticity, and bending strength. This suggests that wood hardness may not reliably indicate wood quality for industrial applications. Consequently, the study recommends considering alternative non-destructive properties, such as the dynamic modulus of elasticity, in future genetic studies of black alder for more accurate assessments of wood quality.
