RESUMOEm sementes de espécies florestais, geralmente ocorre grande variação no desempenho germinativo em relação aos substratos em laboratório, sendo necessário determinar o tipo de substrato que proporciona a melhor germinação para cada espécie florestal. Este estudo objetivou avaliar o comportamento de germinação (porcentagem de germinação e índice de velocidade de germinação -IVG) das sementes da leguminosa florestal Anadenanthera peregrina (L.) Speg. (Fabaceae -Mimosoideae), submetidas a diferentes substratos (areia, papel filtro e vermiculita). Os substratos que demonstraram maiores valores de IVG foram vermiculita e papel filtro, sendo que a vermiculita também propiciou maior porcentagem de germinação, indicando que esse substrato é o mais adequado para testes de germinação de sementes de A. peregrina.Palavras-chave: espécie florestal, Anadenanthera peregrina, germinação, substrato de germinação. Seed Germination of Anadenanthera peregrina (L.) Speg. with Different Substrates under Laboratory Conditions ABSTRACTIn seeds of forest species, usually there is a great variation in the seed germination performance in relation to the substrate in laboratory, so it is necessary to determine the type of substrate which allows a better germination for each forest species. This study aimed at evaluating the behavior of seed germination (percentage of germination and index of germination speed -IVG) of the legume forest species Anadenanthera peregrina (L.) Speg. (Fabaceae -Mimosoideae), submitted to different substrates (sand, filter paper and vermiculite). The substrates that demonstrated higher values of IVG were vermiculite and filter paper, and vermiculite also allowed higher percentage of germination, indicating that this substrate is the most adequate for germination tests of seeds of A. peregrina.
