Copper II is a common fungicide, especially in wood preservative formulations. Published research has noted fungal stimulation when fungi are subjected to sub-lethal amounts of copper ions. In this paper, the use of copper salts to stimulate spalting, as measured by fungal pigment production is investigated. At 1.0 kg/m3 copper sulfate, Xylaria polymorpha increased external zone lines when grown on sugar maple (Acer saccharum). Use of this experimental method to produce spalted wood should yield increased external spalting without an associated increased loss in machinability.

Stimulation pilzbedingter Verfärbungen von Zuckerahorn mittels subletaler Kupferdosierungen


Kupfer II ist ein herkömmliches Fungizid, das insbesondere in Holzschutzmitteln verwendet wird. Aus der Literatur ist bekannt, dass Pilze angeregt werden, wenn sie einer subletalen Dosis an Kupferionen ausgesetzt werden. Im vorliegenden Artikel wurde untersucht, wie Kupfersalze pilzbedingte Verfärbungen stimulieren. Die Pilzpigmentproduktion wurde bestimmt. Bei einer Kupfersulfatmenge von 1,0 kg/m3 nahmen die durch Xylaria polymorphia auf Zuckerahorn (Acer saccharum) erzeugten Grenzlinien zu. Mit diesem Verfahren sollte es möglich sein, ausgeprägtere Holzverfärbungen zu erhalten ohne die damit in der Regel schlechtere Bearbeitbarkeit in Kauf nehmen zu müssen.
