Vochysia tucanorum Mart.: an aluminum-accumulating species evidencing calcifuge behavior

Background and aims Acidic soil occupies 30% of the world’s ice-free land, and exchangeable aluminum (Al) availability increases under these conditions, being toxic to many plant species. However, some plants accumulate Al without damage to their metabolism. Vochysia tucanorum is an Al-accumulating species endemic to the cerrado vegetation with acidic soils in South America. Here, we predict that it is a calcifuge species.
