Abstract:
Human activity on the environment, exploiting it in a disorderly manner, has negatively interfered with the balance of the ecosystems. There's currently a huge demand for floristic replenishment technology, especially native revegetation that has been destroyed. Therefore, the objective of this study was to evaluate, in a greenhouse, the initial growth of six native tree species from Goiás's Cerrado: Dipteryx alata (baru), Hymenaea courbaril (jatobá), Inga laurina (ingá), Campomanesia cambessedeana (gabiroba), Sterculia striata (chichá) and Jacaranda cuspidifolia (caroba) under the inoculation of Arbuscular Mycorrhizal Fungus (AMF) spores Glomus clarum in soil with low and high non-sterilized phosphorus (P). The experiment was conducted for 180 days. Plants of all species were colonized, and some species presented greater colonization. Inoculation with Glomus clarum increased vegetative growth: shoot dry matter (MSPA) and root dry matter (MSR) of caroba and gabiroba species. In the specific case of carob, a synergistic effect was observed between P application and AMF inoculation, promoting a 233% increase compared to uninoculated plants. Jatobá responded only to the application of P in all variables. No difference were shown variables studies of in baru, chichá and ingá.
