Both species were successfully rooted; P. angolensis was a faster rooting species (86% after 61 days) compared with B. spiciformis (59% after 154 days). Regression analysis suggested that P. angolensis had more stored carbohydrates, which facilitated its rooting while B. spiciformis was more dependant on current assimilates produced during the period of propagation. The results of this study suggest that it is possible to develop clones of genetically superior trees of B. spiciformis and P. angolensis for use in agroforestry or reforestation programmes.
