Název v původním jazyce

Effect of site conditions on extractives content in Sessile oak

Popis výsledku v původním jazyce

Oak wood is considered as European native species with the highest heartwood durability. At present, Sessile oak is classified as &quot;durable&apos; (durability class 2) according to EN 350-2. In numerous studies it was proven that there is a significant difference in fungal decay susceptibility between wood from different oak trees, especially when exposed in contact with ground. Extractives content, particularly phenolic ones, is the most important factor influencing oak durability. The study investigates the between-tree variability for extractives content in Sessile oak and interprets it according to the site quality of the tree. The total content of extractives, phenolic extractive concentration and ellagitannins known to be present in oak wood (castalagin, vescalagin and ellagic acid) were characterized in the sessile oak wood from four different quality growing sites. Experiment is based on the sampling of 24 trees, older than 100 years. In addition, the distribution of extractives in the stem along the radius at breast height was studied.
