Streszczenie: White acacia (Locust tree, Robinia pseudoacacia L.) is a fast growing tree species, which can produce high quality wood within 15-20 years and is therefore economically very important. The structure and wood properties of 7 locust clones (Robinia pseudoacacia L.var.rectissima Raber) at ages between 7 and 35 years were investigated. They were cultivated in four schemes of plantation densities on carbonate chernozems (CH), alluvial (FL) and alluvial-meadow (Fle) soils in North Bulgaria. The obtained results show that there is good correlation between thickness of wood fibers, thickness of cell walls, wood density and mechanical properties. High quantities of extractive substances are found in the cell lumens, due to which the old locust tree wood has been classified as highly resistant against the wood-destructing basidiomicetes Serpula lacrimans (Wilf.ex Fr.) and Polyporus sulphureus (Bull.ex Fr.) according to EN 350/1-93. Our analysis showed insignificant differences between dry mass losses of the studied clones. We suggest that such differences are due to site influence, plantation densities and tree age.
Słowa kluczowe: robinia pseudoacacia l.v.rectissima; wood structure and properties; resistance against decay
