Contribuição ao estudo morfo-anatômico de espécies de Micropholis (GRISEB.) Pierre (Sapotaceae. juss.) no Estado do Pará.

Abstract

The study of morpho-anatomical characters functions as an essential support to researches of characterization and utilization of wood from Brazil and the world because it allows a correlation between wood structure and its various properties. Among the various traded woods, we find a significant group which belongs to the Sapotaceae. It forms one of most characteristic families of Amazon flora, with approximately 25% of the total volume of wood. This represents a very larger volume of woody species, however only a very small fraction is being used. The aim of this study was to determine the main morpho-anatomical characteristics of Micropholis species found in the State of Pará, and therefore, to provide data about the morphology and anatomy of wood. This will avoid that such species be wrongly identified and it also contributes to the trade of this taxonomic group. From the surveys accomplished in IAN and MG Herbaria, it was possible to detect the species of Micropholis genus that are more traded and collected from the State of Pará, through collection made in timber companies, in Flona of Tapajós and in the Experimetal Field of Embrapa Amazônia Oriental-Mojú.
