However, there are little data about this subject, especially on tropicalforest species. This study aimed to evaluate the macronutrient retranslocation dynamic and the influence ofecological (P: pioneer x NP: non-pioneer) and phenological (ND: non-deciduous x D: semideciduous /deciduous) characteristics on the macronutrient content of leaves of five tree species on monospecificplantations in the Brazilian Amazon: Acacia mangium Willd., Parkia decussata Ducke, Dipteryx odorata (Aublet)Willd., Jacaranda copaia (Aubl.) D. Don and Swietenia macrophylla King. Photosynthetically active green leavesand senescent leaves (leaf litter) were collected. Retranslocation was estimated through an equationproposed by Attiwill, Guthrie and Leuning (1978). The pioneer species presented higher foliar contents ofN; the non-pioneer species presented higher contents of K, Ca and S; and the results were inconclusive forP and Mg. The deciduous species presented higher foliar contents of K and of P, whereas the foliarcontents of N, Ca, Mg and S were virtually identical between the phenological groups. The internalretranslocation of foliar nutrients in pioneer and non-deciduous species was higher than that of nonpioneerand deciduous species. 2016 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303044042011 https://www.redalyc.org/journal/3030/303044042011/ https://www.redalyc.org/journal/3030/303044042011/html/ https://www.redalyc.org/journal/3030/303044042011/303044042011.epub https://www.redalyc.org/journal/3030/303044042011/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
