Abstracts... Hamburg: Universitatc1994  ap. 62-69.  aNear Manaus, Brasil, a recultivation experiment of a fallowing agricultural area is presently carried out. A polyculture system has been implanted to reach maximum economical and ecological stability. It includes twelve perennial and three annual or biannual useful plant species. Some of them are unknown in European countries. In four different combinations the plant species are grown together to give rise to the following products: latex production, pulpa for juice, icecream, desserts, seeds for chocolate; fruits, palmito, food colourings, weaving material, nuts, timber, oil, copra, fibre, etc. Additionally to these ecologically well adapted plant species the exotic useful plant species Citrus sinenses is planted. Several ecological and practical aspects of the plant management were considered as criteria of selecting the suitable plants, basing not only on their resistance to diseases and growth behaviour but also on the circumstance that the plant products have to be accepted by the Amazonian people. The products must be of commercial value and must be suitable for the transport to regional markets or even for the export. Besides the implantation of useful plants during the recultivation process the evaluation, integration and, finally, the exploration of the spontaneous vegetation in the experimental fields is being carried out. A first survey shows the existence of at least 25 plants species of pharmaceutical potential.  aenvironmental degradation  aforest trees  aBactris Gasipaes  aBixa Orellana  aCarapa Guianensis  aCarica Papaya  aCitrus Sinensis  aCocos Nucifera  aCultivo Multiplo  aDesenvolvimento Sustentável  aDeterioração do Solo  aEspécie  aEssência Florestal  aFloresta Tropical Úmida  aHevea  aManihot Esculenta  aPueraria Phaseoloides  aRecuperação do Solo  aSchizolobium Amazonicum  aSwietenia Macrophylla  aTheobroma Grandiflorum  aVigna Unguiculata  aZea Mays  aAgrofloresta  aagroforest  aAmazonas  aBertholettia excelsa  aBrasil  aManaus  aMultiple crooping  aReclamation  aSustainability  aTropical rain forest1 aGASPAROTTO, L.1 aPREISINGER, H.1 aVOB, K.1 aLIEBEREI, R.
