Abstract

Provenance trials of Pinus caribaea Morelet of the international series coordinated by the Oxford Forestry Institute, University of Oxford, were established at the Mariti State forest (1000 m) in 1974 and the KwaMbonambi State forest (65 m) in 1973. The trials were assessed in 1980 for volume under bark (VUB) and wood density (DEN) and these two traits plus the derived indices of within sample density variation (VAR) and dry matter index (DMI) were analysed. Statistically, there were highly significant differences (p
