\n Abstract The biological durability of wood is frequently determined in laboratory tests with monocultures of different decay fungi under ideal conditions for fungal growth. To avoid contamination with mould and inhibition of fungal growth, wood specimens need to be sterilized using different methods. To determine the mass loss of wood blocks during incubation, the initial total dry mass is needed but should be determined without oven-drying to avoid the loss of volatile compounds of the tested wood. In this study the effect of different sterilization techniques in combination with different methods of determining the oven-dry weight on mass loss (ML F ) in agar plate wood block tests was investigated. No significant ML F differences were observed between sterilization through gamma radiation, steam, autoclaving, ethanol dipping and oven-drying. Solely, non-sterilized specimens showed reduced ML F , since the test fungus was inhibited by mould growth. Oven-drying of wood species that contain volatile and resistance-affecting compounds such as Scots pine ( Pinus sylvestris ) led to reduced biological durability and should either be avoided or adapted to kiln-drying temperatures usually applied in practice.\n

Numerous parameters can affect the mass loss by fungal decay (MLF) in laboratory durability tests and therefore being decisive for the resulting durability classification. Among others, the dimension of the wood specimen and the time of incubation impact on fungal decay. Hence, both parameters were examined within this study using 19 different specimen formats and four different incubation times. Specimens of larch heartwood (Larix decidua Mill.) were incubated with pure cultures of the brown rot fungus Coniophora puteana. Scots pine sapwood (Pinus sylvestris L.) was used as a reference. The wood specimens’ format turned out to significantly affect both mass loss by fungal decay (MLF) and resulting x-values when MLF of larch was compared with that of the reference Scots pine sapwood. Both measures were highest for specimen formats with moderate surface-volume ratios. MLF and x-values depended on specimen size and shape as well as on the time of incubation.

\n The experimental basis for testing the biological durability of wood often includes incubation experiments with wood-destroying basidiomycetes. Numerous parameters can affect the mass loss by fungal decay (MLF) in laboratory durability tests and therefore being decisive for the resulting durability classification. Among others, the dimension of the wood specimen and the time of incubation impact on fungal decay. Hence, both parameters were examined within this study using 19 different specimen formats and four different incubation times. Specimens of larch heartwood (Larix decidua Mill.) were incubated with pure cultures of the brown rot fungus Coniophora puteana. Scots pine sapwood (Pinus sylvestris L.) was used as a reference. The wood specimens’ format turned out to significantly affect both mass loss by fungal decay (MLF) and resulting x-values when MLF of larch was compared with that of the reference Scots pine sapwood.

Das Projekt beinhaltet Untersuchungen zu einem möglichen Befallsdruck an Maststandorten, an denen es zu Frühausfällen kam, d.h. die Standzeit der Masten maximal 15 Jahre betrug. Zur Untersuchung eines möglicherweise erhöhten Befallsdruckes an den ausgewählten Maststandorten, verursacht durch bereits im Boden angesiedelte Pilz- und Bakterienstämme, wurden Freilandversuche unter Berücksichtigung verschiedener Bodenklassen durchgeführt. Außerdem wurden über die gesamte Projektlaufzeit weitere Mastfrühausfälle auf einen Befall durch holzzerstörende Pilze sowie deren Schutzmittelmenge zum Zeitpunkt des Ausfalles hin untersucht.\nVorläufige und bereits berichtete Ergebnisse haben gezeigt, dass einige Standorte eine überdurchschnittlich hohe Befallsaktivität aufweisen. Der Befall konnte nicht auf einzelne Bodenklassen und Bodentypen zurückgeführt werden. Diese vorläufigen Ergebnisse konnten durch die durchgeführten Freilandversuche bestätigt werden. Der Befallsdruck ist dabei standortabhängig und bei der Mehrzahl der untersuchten Maststandorte auf die unmittelbare Mastnähe beschränkt. Allerdings gibt es auch Standorte, wo ein erhöhter Befallsdruck nicht auf die unmittelbare Mastnähe beschränkt ist.\nWeitere Untersuchungen von Mastfrühausfällen zeigten an einer Vielzahl von Mastabschnitten einen Befall durch holzzerstörende kupfertolerante Pilze. Es wurde ebenfalls eine Bestimmung des Kupfergehaltes zum Zeitpunkt des Mastausbaues durchgeführt. Dabei zeigte sich, dass ein Befall durch kupfertolerante Pilze in vielen Fällen nicht nur auf Masten mit einer zu geringen Einbringmenge des Schutzmittels zurückzuführen ist.},\n\tbooktitle = {Deutsche {Holzschutztagung} – {Trends} und {Chancen}},\n\tpublisher = {Deutsche Gesellschaft für Holzforschung (DGfH)},\n\tauthor = {Gellerich, A. and Bollmus, S. and Militz, H.},\n\teditor = {Militz, H.},\n\tmonth = sep,\n\tyear = {2012},\n\tpages = {74--82},\n\tfile = {8_Gellerich:C\\:\\\\Users\\\\Eva\\\\Zotero\\\\storage\\\\TRICGBIF\\\\8_Gellerich.pdf:application/pdf},\n}\n\n

\n Das vorgestellte Projekt hatte eine vierjährige Laufzeit und wurde in enger Zusammenarbeit mit dem Energieversorgungsunternehmen RWE bearbeitet. Das Projekt beinhaltet Untersuchungen zu einem möglichen Befallsdruck an Maststandorten, an denen es zu Frühausfällen kam, d.h. die Standzeit der Masten maximal 15 Jahre betrug. Zur Untersuchung eines möglicherweise erhöhten Befallsdruckes an den ausgewählten Maststandorten, verursacht durch bereits im Boden angesiedelte Pilz- und Bakterienstämme, wurden Freilandversuche unter Berücksichtigung verschiedener Bodenklassen durchgeführt. Außerdem wurden über die gesamte Projektlaufzeit weitere Mastfrühausfälle auf einen Befall durch holzzerstörende Pilze sowie deren Schutzmittelmenge zum Zeitpunkt des Ausfalles hin untersucht. Vorläufige und bereits berichtete Ergebnisse haben gezeigt, dass einige Standorte eine überdurchschnittlich hohe Befallsaktivität aufweisen. Der Befall konnte nicht auf einzelne Bodenklassen und Bodentypen zurückgeführt werden. Diese vorläufigen Ergebnisse konnten durch die durchgeführten Freilandversuche bestätigt werden. Der Befallsdruck ist dabei standortabhängig und bei der Mehrzahl der untersuchten Maststandorte auf die unmittelbare Mastnähe beschränkt. Allerdings gibt es auch Standorte, wo ein erhöhter Befallsdruck nicht auf die unmittelbare Mastnähe beschränkt ist. Weitere Untersuchungen von Mastfrühausfällen zeigten an einer Vielzahl von Mastabschnitten einen Befall durch holzzerstörende kupfertolerante Pilze. Es wurde ebenfalls eine Bestimmung des Kupfergehaltes zum Zeitpunkt des Mastausbaues durchgeführt. Dabei zeigte sich, dass ein Befall durch kupfertolerante Pilze in vielen Fällen nicht nur auf Masten mit einer zu geringen Einbringmenge des Schutzmittels zurückzuführen ist.\n
