During the first phase of the project (january 1, 1995 until april 30, 1998), the influence of the water and element supply of tree different plantation systems on the growth and wood formation of eight native tree species (Swietenia macrophylla, Carapa guianensis, Cedrela odorata, Dipterex odorata, Hymenaea courbaril, Ceiba pentandra, Virola surinamensis, Tabebuia heptaphylla) was investigated. In 1998, the data were analyzed. The results subsequently served as a basis for the second phase of the project (comp. chapter 5) which should give deeper insight into the relationship between exogenous and endogenous input, the plant metabolism, and the wood formation and wood quality of plantation-grown trees. due to the results obtained in these studies in the second phase of the project, special attention is given to the subsequent species : Swietenia macrophylla, Carapa guianensis, Cedrela odorata, Dipterex odorata, and Hymenaea courbaril. Corresponding investigations are carried out in the plantation system I (monoculture system) in comparison to system III (enrichment system). Supplementary studies on the environment-tree growth relationship of Swietenia macrophylla and Carapa guianensis are carried out in a mixed culture system (system II, comp. Schmidt et al. 1999, chapter 5). For the study on wood quality and the significance of endogenous factors for wood formation experimental areas of the Instituto Nacional de Pesquisa da Amazonia ( INPA, Manaus) 45 km north of Manaus, and some trees from primary forests of the region were included in this study.
