Plathymenia reticulata Benth occurs in open formations of the Brazilian Cerrado and Atlantic Forest. The seeds are affected by pathogens that reduce germination. The use of fungicides is defined for many species, but, for forest species, further studies are necessary. Thus, the aim of this study was to evaluate and identify the physical and physiological quality of mahogany seeds that are coated with fertilizer and fungicide. The treatments were: seed coating with sand + lime + fungicide with different doses of fertilizers. The seeds were evaluated in the laboratory and in a greenhouse. The experiment was conducted in a completely randomized design with four replications of 50 seeds. The treatment with 50 g of fertilizer had the highest weight out of 1000 seeds. There were no infested seedlings among the coated seeds. The coating maintained the quality of the seeds and the coating with high doses of fertilizer inhibited the germination, germination speed index (GSI), emergence and emergence speed index (ESI) of the mahogany seed.
