Whereas there are some studies on the volatile composition of the essential oil from the leaves of <i>Betula pendula</i> Roth, only limited information is available on the odor-active constituents of birch wood. To close this gap, the odorants of birch wood were investigated by means of instrumental and sensory analyses, including techniques such as gas chromatography-flame ionization detection/olfactometry, high-resolution gas chromatography-mass spectrometry, and heart-cut two-dimensional high-resolution gas chromatography-mass spectrometry/olfactometry. Overall, a total of 20 odorants was (tentatively) identified on the basis of their respective odor qualities and retention indices and mass spectra by comparison with reference compounds. It was shown that birch wood odor is dominated by a series of terpenes, terpenoids and phenyl compounds originating from the degradation of lignin and aldehydes, ketones and acids originating from fatty acid degradation. By a sensory evaluation of the birch wood, the predominant odor attributes were determined to be <i>earthy</i>, <i>pencil-like</i>, <i>corky/mouldy</i>, <i>grassy</i>, <i>fatty</i>, <i>fruity</i>, <i>green tea-like</i>, <i>herb-like</i>, <i>vanilla-like</i>, and <i>vinegar-like</i>.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"58 5-6","pages":"1761 - 1779"},"PeriodicalIF":3.1,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00226-024-01575-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142187367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent strength grading machines, lasers and cameras are used to detect surface characteristics such as the size and position of knots and local fibre orientation. Since laser dot scanning only gives reliable information about the fibre orientation in the plane of board surfaces, simple assumptions are usually made to define the inner fibre orientation to model timber boards. Those models would be improved by better insight into real fibre deviation around knots. In the present work, a laboratory method is developed to evaluate growth layers geometries and fibre orientation, solely based on the fact that the fibers are parallel to the tree rings and without any further assumptions. The method simply relies on color scans and laser dot scans of Douglas fir (<i>Pseudotsuga menziesii</i>) timber specimen sections revealed by successive planing.

In this paper, the spatial relationships of the conducting tissues among the main stem, root and rhizome of the culm base are explored. The culm base of a <i>Chimonobambusa tumidissinoda</i> was used for the analysis and high-resolution X-ray microtomography (μCT) was employed. A deep learning algorithm was used to segment the conducting tissue from the culm base. 3D model reconstruction and semi-quantitative characterization of the conducting tissue were realized. It was found that the anatomical characteristics among the main stem, root and rhizome are different, but the conducting tissues in these structures are interconnected in different ways. The transverse conducting tissue mainly originated from the rhizome rather than the root, and its thickness gradually decreased from the bottom of culm base to its top, contrary to the structure of the axial conducting tissue. The results indicate that μCT combined with deep learning segmentation effectively visualizes complex conducting tissue structures, volume filtering enhances detailed observation of network structures within conducting tissues, which provides new insights into the bamboo’s culm base structure and evidence of the sophisticated and interconnected fluid motion pathways among the different tissues of the culm base.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"58 4","pages":"1585 - 1603"},"PeriodicalIF":3.1,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
