PAIVA, João Rodrigues de. Conservation "Ex Situ" of Plantas Genetic Resources. In the Tropical Rain Region. Acta Amaz. [online]. 1994, vol.24, n.1-2, pp.63-80. ISSN 0044-5967.  http://dx.doi.org/10.1590/1809-43921994242080.

In the last two decades the Amazon region has been submitted to acelerated and disorganized development process that created serious worries about the future of its genetic resources. The situation has a tendency to aggravate because, at this time, there is no available ex situconservation method for tropical species genetic resources. Some research works have shown the importance of species diversity, plant density and genetic variability as strategies utilized by the plants to survive in the heterogeneouness of the tropical ecossystems. This paper to discuss and present an ex situgenetic resources conservation method for autochthonous species in the Amazon region.
