Popis:	In 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.
