This work aimed to evaluate the response of five indigenous arboreal species, submitted to extreme frost stress in an agroforest system (AFS) in Florianópolis, Santa Catarina (lat. 27º35' S, long. 48º34' W and alt. of 1,84 m). The soil is a distrophic Hydromorphic Quartzarenic Neosoil, with sandy texture, and high watertable flotation.The experiment was arranged in a randomized complete design, with seven plots of ten trees each. The analyzed parameters were: height, number of leaves, average height increase and number of leaves of each tree, measured every four months, percentage of burned leaves and rate of survival of the plants after frost. The statistical parameters analyzed were: average and standard deviation.The Tukey test at 5% probability was used to analyze the results. The ingás (Inga uruguensis and Inga sessilis) showed tolerance to frost and a high potential for AFS, under the edafo-climatic conditions studied. The species tucaneira (Citharexylum myrianthum) did not show good tolerance to frost but it did show a high resprouting rate. The species corticeira (Erythrina falcata), olandi (Calophyllum brasiliense) and licurana (Hieronyma alchorneoides) showed a high mortality rate under frost, but it did not show a good potential for AFS under the edafo-climatic conditions studied.
