The current study aimed to identify pathogens, analyzing different seed treatments and substrates for the germination of Cabraleacanjerana and also to indicate instructions testing for laboratory test of the species germination. First, we assessed the moisture content and determined the thousand seed weight. In order to assess the pathogens associated with the seeds, health testing was performed at different seed treatments: T1 - Control; T2-Captan®; T3-Maxim®; T4-Sodium hypochlorite; andT5-AgrotrichPlus®. The germination testwas performed based ona factorial designwithfive seed treatmentsand threesubstrates (on blotting paper, vermiculiteand sand). The seeds showedmoisture contentandthousand seed weight of41.2% and457.3g, respectively. The main fungi genera associated withCabraleacanjerana seeds were: Penicilliumspp., Fusarium spp., Cladosporium spp., Pestalotia spp. and Phomopsisspp..Theseed treatment withCaptan®, Maxim®andsodium hypochloritewas effectivein reducing the incidenceofPenicilliumspp., but onlythe last twoshowedthe greatest potential forseed germination,regardless theused substrate. Treatment with Agrotrich Plus® had the lowest percentage of germination and increased incidence of Fusariumspp. Asepsis with 1% per 2’ sodium hypochlorite and seeding substrate over vermiculite is indicated for the germination tests of Cabraleacanjerana seeds and the first counting can be performed at the 19th day and the final one at the 30th day after the test.
