Liming is benefi cial for plants as it promotes pH elevation, neutralization of toxic aluminum, increase in calcium (Ca2) and magnesium (Mg2) supply, and provides greater root systems. However, it is known that diff erent species, mainly those native to the Cerrado, respond in diff erent ways to this technique. Given the above, the objective of this study was to determine how Hymenaea stigonocarpa (“Jatobá-doCerrado”) seedlings respond to liming in Dystrophic Red Latosol. The plants were cultivated in four-liter pots, submitted to diff erent base saturation (natural soil, 30, 45, 60 and 75% V) and maintained in a greenhouse. Biometrics, biomass, nutritional content and physiological parameters were evaluated. A diff erence in Ca2 and Mg2 contents between leaves and stems was observed, leading to signifi cant reductions in stomatal conductance, transpiration, internal CO 2 concentration and internal and external CO 2 concentration ratios, resulting in a reduction of the investment in growth and biomass. Given these results, there is no need for liming in the production of H. stigonocarpa seedlings in a Dystrophic Red Latosol.
