ABSTRACT
Monoterpenes form part of the natural defenses against pathogenic fungi in conifers. As a result of exposure to kiln-drying, up to 50 percent of the monoterpene content of softwood timber can be lost. This paper reports an in vitro investigation of the effect of high monoterpene vapor concentration on the formation of piginented mycelium and coremia/perithecia by Ophiostoma piceae, a common cause of stain in timber. Of five commonly occurring monoterpenes tested, [alpha]-pinene, [beta]-pinene, [Delta]3-carene, and myrcene caused relatively small radial growth rate reductions but had considerable inhibitory effects on mycelial pigmentation and ...
