A greenhouse experiment was carried out to determine the mycorrhizal dependency of lulo (Solanum quitoenseLam.). An experimental design completely randomized was used, treatments were arranged in factorial combination 3x2, which consisted of the combination of three soil solution phosphorus (P) concentration (0.002, 0.02 and 0.2 mg L -1 ) and two levels of inoculation with the mycorrhizal fungus Glomus aggregatum (inoculated and uninoculated). Foliar P content was monitored as a function of time.
