Untersuchung der kapillaren Transportwege im Weißtannenholz

Abstract: Die Transportwege für Flüssigkeiten in Weißtannenholz werden nach einem Kapillarsaugversuch mit gefärbtem Wasser und einer Vakuum-Druck-Imprägnierung mit fluoreszierend eingestelltem EP-Harz mikroskopisch untersucht. Primäre Eindringwege sind die Längstracheiden; die sie verbindenden Hoftüpfel sind die Strukturen, die die Tränkergebnisse dominant bestimmen. Über die Holzstrahlen findet dagegen kein wesentlicher Flüssigkeitstransport statt; normales Kernholz ist weitgehend impermeabel. lm Splint wird die Flüssi… Show more

“…As such, the decreased proportion of latewood in samples taken from near the radial center of the log may be an additional factor that explains the lower permeability of wood from this zone. Latewood (in dried wood) is usually more permeable than earlywood because of its higher resistance to pit aspiration (Phillips 1933;Liese and Bauch 1967;Siau 1984Siau , 1995Richter and Sell 1992;Hansmann et al 2002). In latewood, the higher resistance to pit aspiration is usually attributed to the greater rigidity of pit membranes and thicker cell walls (Comstock and Côté 1968).…”
