NATURAL DECAY RESISTANCE OF FOREIGN WOODS: LABORATORY TESTS OF AFRICAN OAK, PARINARIUM, WISHMORE, AND LIBERIAN PINE
Abstract
According to a four-class scale of decay resistance--highly resistant, resistant, moderately resistant, and nonresistant--heartwood samples from two logs of African oak (Gilbertiodendron preussii (Harms) J. Leonard) tested by the soilblock method were indicated to be resistant to both brown and white rot fungi. Three other African species appraised in the same limited manner, parinarium (Parinari holstii Engelman), wishmore (Tarrietia utilis Sprague), and Liberian pine (Tetraberlinia tubmaniana J. Leonard), were only moderately resistant. These results compare to earlier work when ekki (Lophira alata Banks ex Gaertn. f.) was indicated to be highly resistant and kokrodura (Afrormosia elata Harms) from resistant to highly resistant.
