SANITY TESTING AND GERMINATION IN Cabralea canjerana (Vell.) Mart. SEEDS

O presente estudo teve como objetivo identificar pat\uf3genos, analisar diferentes tratamentos de sementes e substratos para germina\ue7\ue3o de sementes de Cabralea canjerana e ainda indicar instru\ue7\uf5es para realiza\ue7\ue3o de teste laboratoriais de germina\ue7\ue3o da esp\ue9cie. Primeiramente, foi avaliado o teor de umidade e determinado o peso de mil sementes. Para avaliar os pat\uf3genos associados \ue0s sementes, foi realizado o teste de sanidade com diferentes tratamentos de sementes: T1 \u2013 Testemunha; T2 \u2013 Captan\uae; T3 \u2013 Maxim\uae; T4 \u2013 Hipoclorito de s\uf3dio; e T5 \u2013 Agrotrich Plus\uae. O teste de germina\ue7\ue3o foi realizado em esquema fatorial com cinco tratamentos das sementes e tr\ueas substratos (sobre papel mata-borr\ue3o, vermiculita e areia). As sementes apresentaram teor de umidade e peso de mil sementes, respectivamente, de 41,2% e 457,3 g. Os principais g\ueaneros de fungos associados \ue0s sementes de Cabralea canjerana foram: Penicillium spp., Fusarium spp., Cladosporium spp., Pestalotia spp. e Phomopsis spp. O tratamento das sementes com os produtos Captan\uae, Maxim\uae e hipoclorito de s\uf3dio mostraram-se eficientes na redu\ue7\ue3o da incid\ueancia de Penicillium spp. em sementes de Cabralea canjerana, por\ue9m, somente os dois \ufaltimos proporcionaram maior potencial de germina\ue7\ue3o independente do substrato utilizado. O tratamento com Agrotrich Plus\uae apresentou a menor porcentagem de germina\ue7\ue3o e aumento da incid\ueancia de Fusarium spp. Indica-se para o teste de germina\ue7\ue3o das sementes de Cabralea canjerana assepsia com hipoclorito de s\uf3dio 1% por 2\u2019 e substrato de semeio sobre vermiculita, sendo que a primeira contagem pode ser realizada aos 19 dias e a contagem final aos 30 dias ap\uf3s a instala\ue7\ue3o do teste.The current study aimed to identify pathogens, analyzing different seed treatments and substrates for the germination of Cabralea canjerana 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\uae; T3-Maxim\uae; T4-Sodium hypochlorite; and T5-Agrotrich Plus\uae. The germination test was performed based on a factorial design with five seed treatment sand three substrates (on blotting paper, vermiculite and sand). The seeds showed moisture content and thousand seed weight of 41.2% and 457.3 g, Fusarium spp., Cladosporium spp., Pestalotia spp. and Phomopsis spp.. The seed treatment with Captan\uae, Maxim\uae and sodium hypochlorite was effective in reducing the incidence of Penicillium spp., but only the last two showed the greatest potential forseed germination, regardless the used substrate. Treatment with Agrotrich Plus\uae had the lowest percentage of germination and increased incidence of Fusarium spp. Asepsis with 1% per 2\u2019 sodium hypochlorite and seeding substrate over vermiculite is indicated for the germination tests of Cabralea canjerana seeds and the first counting can be performed at the 19th day and the final one at the 30th day after the test
