Seeds from Schinus lentiscifolius March collected in two mining areas in the state of Rio Grande do Sul, Brazil, were submitted to CuSO4 exposure tests to confirm copper tolerance during germination .and plantule development. The results showed that the two distinct clones respond differently to copper, but both presented tolerance mechanisms. Plantules originated from seeds collected in the area with higher soil copper concentration (minas do Seival) presented toxicity symptoms later as compared to those plantules originated from seeds collected in the area with lower CU² + concentration (mina Sanga Negra).
