The effects is presented of arbuscular mycorrhiza and water regime on seedling mass (mean ± 1SE) of Boswellia. Arbuscular mycorrhizal treatment (AM+) is compared with a control without inoculation (AM−), and water pulse every 2 weeks (SP) during the wet seasons is compared with a control with regular water supply during the wet season (WC). Seedlings in the 12-month category die back aboveground during the 8-month dry period, as a consequence of which there were no differences in biomass between the 4- and 12-month-old seedlings. Different letters (per age class) indicate significant differences between treatments (P < 0.05)
