Boletim de Pesquisa, 8).  aFoi conduzido um experimento na Universidade Federal de Lavras, em Lavras-MG, com o objetivo de avaliar a mobilização de reservas de sementes para as plântulas de seringueira (Hevea spp.). Aos 0, 7, 15, 30 e 50 dias após a repicagem, as plântulas, separadas em parte aérea e raízes, e as sementes (até o 30 dias) foram coletadas, secas a 70 C/72h e, posteriormente, pesadas. Determinou-se o teor de minerais nas sementes. As reservas orgânicas e minerais foram mobilizadas, com excessão dos minerais Ca, Fe e Mn.   Mobilization of reserves in rubber tree seeds (Hevea spp.) An experiment was carried out in Universidade Federal de Lavras, State of Minas Gerais, Brazil, with main aim to evaluate mobilization of reserves from the seeds to the rubber seedlings (Hevea spp.). After 0, 7, 15, 30 and 50 days of experiment, the seedlings were separated into roots, shoots, seeds (these only up to the 30th day) and submitted to drying at 70 c/72h. Then, they were weighed. The macro and micronutrients content was determined. The organic and mineral reserves were mobilized, expect Ca, Fe and Mn.  aAerial parts  aBrasil  acalcio e manganes  aConteudo mineral  aCultivo  aEspecie  aFerro  aHevea  aHevea brasiliensis  aHevea spp  aMato Grosso  aMinas Gerais  aMinerais  aMineral  aMineral content  aMineral nutrients  aMinerals  aNutriente mineral  aParte aérea  aParte aerea de plantas  aPlanta produtora de borracha  aPlantula  aPlantulas  aRaiz  aRaizes  aRoots  aRubber  aRubber tree  aSeed  aSeedlings  aSeeds  aSemente  aSemente de seringueira  aSeringa  aSeringueira  aShoots  aSpecies1 aOLIVEIRA, L.
