Abstract: The invasive processes are responsible for changes in the composition and functioning of ecosystems, causing numerous damages worldwide. However, studies that evidence invasions of tree species are still recent and very scarce. It is believed that phenotypic plasticity, which is a feature that provides greater tolerance to a wide range of conditions, is linked to the invasive species profile. Thus, evidence of extreme situations may have information about invasive species capacity. Considering the above, the present work analyzed the seed germination of 10 forest species, which were divided into two groups, where five were considered as potentially invasive species and five non - invasive species, according to the regeneration capacity in the study region. The germinative analysis was performed at different temperatures (10, 15, 20, 25, 30, 35 and 40 ° C), and in different water potentials (0, -0.25, -0.5, -0.75 e - 1.0 MPa). It can be concluded from Principal Component Analysis (PCA) that there are no distinct behaviors among the groups of species studied (invasive and non-invasive) during germination.
