Study on the Natural Durability of Nineteen Fujian Woods in Xiamen Harbour Waters

The natural durability of 19 Fujian woods was tested in Xiamen harbour waters during 1987-1989. The main results obtained are as follows: Twelve kinds of fouling organisms have been found on the tested panels, among which Balanus sp., Membanipora sp., Coraphium sp., Ostrea sp., Ascidiae p. and Perna sp. were the main kinds. The boring organisms found on the tested panels were Teredo navalis and Martesia striata. However, the 99% of the holes in wood panels were attacked by T. navalis. According to the percentage of destruction attacked by marine borers in panels, the following classifications of borer-resistance of 19 species is proposed: The most durable: Nil The more durable, Nil The moderate durable: C. fortunei, C. kawakamii, A. Confusa, and E. ru busta. The slight durablet C. fordii, C. equisetifolia, C. glauca, O. xylocarpa and L. formosana. The least durable: P. fortunei, A. fortunei, S. octophylla, P.bournei, C. camphora, C. lanceolata, P. massoniana, S. superba, C. axillaris and D. kaki.
