核心材（“幼龄材”）是在靠近木髓的前10-20个年轮中发现的。这篇评论的重点是描述芯材的特点，影响其发生在一棵树和木材utilization.Recent FindingsCorewood的影响的因素已经广泛研究了广泛的商业树种，与一个大的重点火炬松（Pinus taedaL.）。和辐射松（Pinus radiataD. Don）。最近的研究集中在了解芯材的范围和性能受环境，造林和遗传因素的影响程度。芯材对规格木材、板材产品以及纸浆和纸张的影响众所周知，最近的研究考察了芯材对新产品性能的影响。摘要由于林业实践的强化和对更具成本效益的原材料生产的推动，芯材在人工林资源中所占比例的增加是不可避免的。对木材加工的影响可能是积极的，也可能是消极的，这取决于所涉的最终产品。解决芯材带来的问题可能在很大程度上取决于木材加工商调整其系统，以适应未来资源中芯材比例的增加，或改变其产品的性能规格。
Purpose of ReviewCorewood (‘juvenile wood’) is found within the first 10–20 annual rings adjacent to the pith. This review focuses on describing the characteristics of corewood, the factors affecting its occurrence within a tree and the implications for wood utilisation.Recent FindingsCorewood has been extensively researched across a wide range of commercial trees species, with a large focus on loblolly pine (Pinus taedaL.) and radiata pine (Pinus radiataD. Don). Recent studies have focussed on understanding the degree to which corewood extent and properties are affected by environmental, silvicultural and genetic factors. The impacts of corewood on dimension lumber, panel products and pulp and paper are generally well known, and recent research has examined the impact of corewood on the performance of newer products.SummaryAn increase in the proportion of corewood in the planted forest resource is inevitable due to an intensification of forestry practises and a drive for more cost-effective raw material production. The implications for wood processing can be positive or negative depending on the end product in question. Solving the problems posed by corewood may depend heavily on wood processors adapting their systems to accommodate the increased proportion of corewood in the future resource or changing the performance specifications for their products.
