Síndromes de dispersão e propriedades germinativas de espécies de valor econômico na floresta nacional de Tefé (Tefé, Amazonas)

Abstract

Studies on seed dispersal are an important tool for the conservation of vegetal communities, since they seek to clarify the reproductive dynamics of plants, their interactions with abiotic and biotic factors, its regeneration process. The morphological characterization and attractive diaspores of Amazonian forests are relatively scarce, but highly relevant to the determination of the scattering mechanisms and, consequently, to the maintenance of forests. The forests of the Amazon, particularly middle Solimões, little is known about the ecology of dispersal of plant species. In this pioneering study, six species with potential national forest timber Tefé were systematically investigated to determine their dispersal syndromes and contribute to future conservation and management plans in this portion of the Amazon. This study refers to seed dispersal mechanisms of six species of economic potential of the National Forest of Tefé, Amazonas. The species investigated were Hirtella hebeclada, Parkia nitida, Protium spruceanum, Iryanthera laevis, Couma macrocarpa and Ocotea sp.. The diaspores possessed the characteristics they are dispersed predominantly by zoochory.
