“…The variability of wood decay resistance among wood lots was then assessed only on lowland provenances as provenances from natural stands were much older and age has been reported to influence natural durability (Van Acker et al, 2003;Viitanen et al, 1997).…”

Abstract• Decay resistance of larch (Larix sp.) to fungi was evaluated on heartwood samples belonging to 3 species (L. decidua, L. kaempferi and their hybrid), 3 races of European larch (polonica, sudetica and alpine), 13 wood lots (populations) and 313 trees.• Larch wood appeared, on average, as moderately durable although a high variability was observed. At the sample level as well as at the mean individual tree level, durability ranged from class 1 to 5 according to EN 350-1 standard. At the population level, larch wood varied from 'durable' to 'slightly durable'. Genetics played a major role in decay resistance at the species, provenance and tree levels. Environmental factors such as the position of heartwood samples and the age of trees were also identified as a source of variability.• The most durable wood was not necessarily from old native alpine stands of European larch: some young larches from faster growing lowland origins also produced durable wood.• Genetic improvement of larch wood durability appeared therefore likely by the selection of the best populations for decay resistance as well as from the selection of individuals.

Au niveau arbres et échantillons, la durabilité naturelle s'étend de la classe 1 à 5 suivant la norme EN 350-1. Suivant les origines, le bois de mélèze peut être classé comme 'durable' à 'faiblement durable'. Les facteurs génétiques jouent un rôle significatif sur la résistance à la dégradation du bois aux niveaux espèce, provenance et arbre. Des facteurs environnementaux tels que la position des échantillons au sein du duramen et l'âge des arbres ont également été mis en évidence.• Le bois à plus forte durabilité ne provient pas exclusivement des vieux peuplements naturels de mé-lèze alpin : certaines origines de mélèze cultivées à basse altitude et constituées d'arbres plus jeunes et à croissance rapide peuvent aussi produire du bois durable.• L'amélioration génétique de la durabilité naturelle du mélèze apparaît donc comme envisageable au travers de la sélection des meilleures populations et des meilleurs individus.

“…28,29 On the other hand, it is known that C. versicolor is highly effective in effecting the decomposition of hardwood components, while P. placenta is more active in the case of softwood components. 30,31 These reports can help one to understand the difference in sensitivity between P. placenta and C. versicolor. According to the nature and concentration of glucosylamines, the kinetic growth of fungi was differently affected by these compounds.…”

“…Fungal attack of specimens was performed in Petri dishes with a diameter of 100 mm according to modified Standard EN 113 [28], i.e., specimens with another shape and another method of sterilization were used, and their exposition in fungal mycelia at a temperature of 24 ± 2 • C and a relative air humidity of 90% ± 5% lasted for 6 weeks instead of 16 weeks, according to the rapid screening test by Van Acker et al [29].…”

The European beech (Fagus sylvatica L.) wood was thermally modified in the presence of paraffin at the temperatures of 190 or 210 °C for 1, 2, 3 or 4 h. A significant increase in its resistance to the brown-rot fungus Poria placenta (by 71.4%–98.4%) and the white-rot fungus Trametes versicolor (by 50.1%–99.5%) was observed as a result of all modification modes. However, an increase in the resistance of beech wood surfaces to the mold Aspergillus niger was achieved only under more severe modification regimes taking 4 h at 190 or 210 °C. Water resistance of paraffin-thermally modified beech wood improved—soaking reduced by 30.2%–35.8% and volume swelling by 26.8%–62.9% after 336 h of exposure in water. On the contrary, its mechanical properties worsened—impact bending strength decreased by 17.8%–48.3% and Brinell hardness by 2.4%–63.9%.
