Auswirkung von Kernrissen und Längskrümmung auf die Ausbeute von 32-jährigem Plantagen-Eukalyptus (Eucalyptus globulus Labill.)

Abstract

Thirty dominant or co-dominant, straight trees were selected from a 32-year-old thinned plantation of Eucalyptus globulus Labill. Growth strain at tree surface at breast height was estimated using a CIRAD-foret method. Log-end splits in the butt logs were measured. The butt logs were quarter-sawn following a pre-determined sawing pattern. The most common dimensions of sawn boards were 28×105×3000and 28×77×3000 mm.The volume of the curved-edge off-cuts was estimated for each butt log. The end splits in the dried sawn boards were measured and the volume of the wood containing the splits in the boards calculated.
