摘要

本研究的目的是评估物种对木材抗腐朽生物抗性的影响，并提出临界剂量的校正值。为了评估物种效应，在2016年、2017年和2018年期间，在西班牙气候最具代表性的七个地点，对拉里西奥松、苏格兰松和辐射松以及挪威云杉、桉树和甜栗的20x100x750mm3平锯测试样本中，水分含量超过18%的每年天数的演变进行了评估。四种针叶树的建议值为1.0，桉树为2.51，甜栗为1.84。关于物种效应，不可能将与每种物种的不同润湿/释放能力相对应的影响与其裂纹敏感性相分离，这两个方面必须作为“物种因素”一起评估。

Species effect on decay resistance of wood exposed to exterior conditions above the ground in Spain

The objective of this study is to evaluate the effect of the species on the biological resistance of wood against decay and to propose corrective values of the critical dose. To evaluate the species effect, the evolution of the number of days per year with moisture content exceeding 18% was assessed in flat sawn 20x100x750 mm3 test samples of Laricio, Scots and Radiata pines and also of Norway spruce, Eucalypt (globulus) and sweet chestnut during the years 2016, 2017 and 2018, exposed at seven locations in Spain with the most representative Spanish climates. A value of 1.0 is proposed for the four conifers, 2.51 for the Eucalypt and 1.84 for the Sweet chestnut. As regards the species effect it was not possible to separate that corresponding to the different wetting/releasing ability of each species and that of their crack susceptibility, both aspects having to be evaluated together as “species factor”.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
