“…The results obtained for the C. lusitanica wood, which was considered highly resistant, are consistent with those found by Jones et al (2013), which after performing laboratory tests concluded that C. lusitanica wood was resistant to the Gloephyllum trabeum and Trametes versicolor fungi, but was less resistant to the Coniophora puteana fungi. However, the mass loss in none of the cases exceeded 6%, and was classified as very durable or highly resistant.…”

The purpose of this study was to evaluate the natural durability of Cupressus lusitanica, Cryptomeria japonica and Pinus taeda woods subjected to a rotting field trial, through mass loss and deterioration index. The trial was conducted in an open field in the city of Curitibanos, State of Santa Catarina, Brazil, for a 24-month period, with evaluations carried out every 6 months. For developing the study, we used the woods of Cupressus lusitanica (16 years), Cryptomeria japonica (16 years) and Pinus taeda (juvenile=15 years and mature wood>30 years) species, from which test specimens were made with the dimensions of 2.5 x 5.0 x 50.0 cm in thickness, width and length, respectively, following the standards suggested by IUFRO. After 24 months of exposure to the rotting field the woods of C. japonica and C. lusitanica species showed a deterioration index that reflected an evident but moderate attack of fungi and termites, while the woods of P. taeda (juvenile) and P. taeda (mature) showed deterioration index that reflected an intense rotting and intense attack of termites. Regarding the mass loss the woods of C. japonica and C. lusitanica were classified as highly resistant, while P. taeda (juvenile) was considered resistant and P. taeda (mature) was considered moderately resistant. In general, the woods of C. lusitanica and C. japonica showed greater natural durability when used in contact with the soil.

“…2) not as good as the EC model (R 2 = 0.87) . Successful use of NIR to predict ML by decay fungi were also reported for Sequoia sempervirens (Jones et al, 2011) as well as Cupressus lusitanica and C. macrocarpa (Jones et al, 2013). Factors contributing to the lower performance of the ML models were the fact that ML measurements were likelyare less precise than EC measurements and that mass loss by decay fungi wasis not only affected by chemical wood features like heartwood extractives (Hawley et al, 1924) but also by physical and anatomical features like density and porosity (Taylor et al, 2002), which arewere not directly represented in NIR spectra.…”

“…More recently, Kokutse et al 26 found that NIR spectroscopy could be used for the rapid evaluation of shrinkage and fibre saturation point either on teakwood meal and solid. Amusant et al 43 developed successfully a method to predict teak natural durability by using reduced size sample materials as Jones et al 46,47 on cypress and sequoia, respectively, and Bush et al on sugar gum. 48 This is the first report of NIR spectroscopy being used for the evaluation of teak wood total phenolics and individual quinones (4¢,5¢-dihydroxy-epiisocatalponol, 2-(hydroxymethyl)anthraquinone and tectoquinone).…”

Near infrared (NIR) spectroscopy provides rapid and non-destructive analysis of wood properties and composition. In this study, we aimed to use NIR measurement for the prediction of teak phenolic compounds, which are chemical markers for natural durability of wood. Twenty-seven teak trees from two geographical zones (Malaysia and Ivory Coast) were used. On ground heartwood samples, the content of total phenolics and individual quinones (tectoquinone, 2-(hydroxymethyl)anthraquinone, 2-anthraquinone carboxylic acid, 1,4-naphthoquinone and 4¢,5¢-dihydroxy-epiisocatalponol) were determined using high performance liquid chromatography (HPLC). Partial least squares (PLS) regression with NIR spectra on the same samples and phenolic data was used to build NIR models for phenolic contents. The PLS models for the total predicted phenolics and three quinone contents (tectoquinone, 2-(hydroxymethyl) anthra quinone, and 4¢,5¢-dihydroxy-epiisocatalponol) showed a good ratio of performance to deviation (RPD ≥ 2.5), strong coefficients of determination (r 2 ≥ 0.8) and the prediction errors were consistent with the reference method. These results demonstrate that NIR spectroscopy can be reliable for the evaluation of total phenolics and individual quinones in teak heartwood wood meal. NIR spectroscopy is a promising technique for rapidly providing information on the quinone contents in teak wood and indirectly for knowing its natural durability. This finding leads to a precise, non-destructive tool for teak wood quality evaluation.
