Abstract:
... AIMS: Cerrado woody species are divided into a small group of aluminum (Al)-accumulating species and the rest of the woody species. Both groups grow well on acidic and Al-rich soils. We found a Cerrado remnant growing on a calcareous soil with high calcium (Ca) and low Al saturations (m%). We checked whether Al deposition differs between leaf veins and leaf blade, and predicted that plants grown o ...

However, local adaptation of plant populations to Sb toxicity has never been shown thus far. Here we compared Sb tolerance and accumulation between a non-metallicolous (NM) population of Salvia spinosa, and a con-specific metallicolous (M) population from a strongly Sb ...
