Holzeigenschaften von Buchen aus immissionsgeschädigten Beständen

In 48 trees from two immission-damaged beech stands in the Hils, Lower Saxonia, both over 100 years old, the anatomical wood properties at breast height (1,30 m) were investigated. From 24 trees out of each stand 12 trees belonged to damage class 0 and the others to damage class 2. On samples of the annual ring sequence 1975–85 and the undamaged annual ring sequence 1945–1955 fibre length, the water conducting tissue and the percentage of cell species were investigated. No abnormal variations of the anatomical wood properties due to immissions could be found.
