Description

We investigated the light conditions during the decaying procedure with the laboratory test designated in the Japanese Industrial Standard (JIS) K 1571-2004. Experiments were performed using the sapwood of Japanese cedar (Cryptomeria japonica D. Don). The results obtained were as follows :<BR>(1) The mass losses of the untreated wood specimens depended on the light irradiation time during the incubation of Fomitopsis palustris (Berk. et Curt.) Gilbn. & Ryv.). Even greater mass losses occurred after 10 days of culturing under light irradiation and the mass lost about 60% (maximum value) in the 60 days of culturing.<BR>(2) The mass losses were great when culturing was performed using 900ml mayonnaise bottles with screw caps equipped with the range 25-40mm inside diameter of glass tubes as aeration conditions during the incubation of Trametes versicolor (L. : Fr. ) Pilát. Even greater mass losses occurred after 45 days of culturing under the light-shield condition. Also, the wood decay was inhibited by the light irradiation and the irradiation acted to shorten the periods of the mass losses during the incubation of the fungus.<BR>(3) These results may extensively influence the evaluation of the preserving performance of wood preservatives using the laboratory decay test designated in JIS K 1571-2004.
