As to study the influence of the plantation management on the cambial growth dynamics of the trees, the investigations were carried out in three different plantation systems (I) monoculture system, (II) mixed culture system, (III) enrichment system). The anatomical structure of the cambial zone of nine Swietenia and six Carapa trees was investigated by means of light microscopy of small samples collected throughout the year with a borer (diameter l.4 and l.9 mm, respectively). Special attention was givento the formation of increment zones and the state of the cambium (period of cell division/ cambial dormancy). In addition, the growth dynamics in woood formation of ten Swietenia and ten Carapa trees was dated by the "pinning method" from April 1995 until March 1997 in monthly intervals. Due to anatomical characteristics of the wound reactions studied by light microscopy, accurate measurements were carried out for increment measurements &gt O.3 mm.  From these findings, it was concluded that Carapa guianensis Aubl. is more adapted to sustainable growth throughout the yearand under various site conditions compared to Swietenia macrophylla King.  awood anatomy  aAnatomia  aAndiroba  aCarapa Guianensis  aCrescimento  aMadeira  aMogno  aSwietenia Macrophylla  aAmazonas  aBrasil  aGrowth  aManaus1 aBAUCH, J.1 aSACK, M.1 aMULLER, M.  tIn: BAUCH, J.; DUNISCH, O.; GASPAROTTO, L., ed.
