(andiroba), in the Manaus-AM (Brasil). The exodermis reveals a special wall structure of suberinized cells in order to resist drought. The exchange kinetics for calcium showed that the special structure of the exodermis and of the endodermis regulates the flux into the primary xylem. The results indicate that andiroba adapts remarkably to drought and mineral element deficiency which favours this species for mixed plantations at the terra firme of the region of Manaus.  aagroforestry  amultiple cropping  anutrient transport  atropical rain forests  awater deprivation  aAndiroba  aCarapa Guianensis  aCultivo Multiplo  aDeficiência Hídrica  aFloresta Tropical Úmida  aRaiz  aRelação Água-Planta  aTransporte de Nutriente  aAgrofloresta  aAmazonas  aBrasil  aManaus  aPlant water relations  aRoot1 aKUHN, A.
