ABSTRACT
This study evaluated the relationship between soil nutrient content and foliar nutrient content of Calophyllum brasiliense in two sites from the coast of Paraná State, with different fertility conditions. The soils were analysed for chemical attributes and leaves for nutrients, Al, Na and specific leaf area as sclerophylly index. Leaves showed differences only for K, Ca, Cu contents and specific leaf area. The K and Ca contents were higher in the leaves of trees from Rio Velho, while the Cu content and specific leaf area were higher in the leaves of trees from Floresta do Palmito. Al and Na contents in leaves indicated that this species is tolerant to these elements. The specific leaf area indicated that the leaves are sclerophyllous in response to stress conditions due to low nitrogen content in both sites, besides the high Al content and low soil fertility in Floresta do Palmito and high soil salinity in Rio Velho.
