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. Author
