Schinus terebinthifolius is a native forest species which may be used in recuperating degraded areas and in urban afforestation. In order to evaluate the efficiency of methods for separating lots of S. terebinthifolius seeds into vigor levels, five lots of seeds were qualitatively evaluated for their moisture content, germination, first count, accelerated aging (the traditional and the saturated salt methods), germination speed index, average time of germination and seedling length and dry weight. The results showed that the tests of first germination count, accelerated aging at 41 ºC for 72 hours, average time of germination, seedling length and dry matter permitted the separation of S. terebinthifolius seeds into different vigor levels.
