【 摘 要 】

Along with the forecast shortage of the Amazonian forest resources is imminent the need for studies concerning the silvicultural potential of species from other regions like the Atlantic Forest. The purpose of this study was to evaluate the silvicultural characteristics ofAstronium concinnum ,Cariniana   legalis ,Goniorrhachis   marginata ,Kielmeyera albopunctata ,Lecythi pisonis ,Manilkara   bella ,Basiloxylon brasiliensis ,Spondias venulosa ,Vitexsp. andZeyheria   tuberculosa , native Atlantic Forest species occurring in Espírito Santo state. The species were planted in full sun in pure stands, with spacing of 2 x 2 m. The stands had ages between 21 and 25 at the time of final evaluation and were conducted at Vale Nature Reserve, in the municipalities of Sooretama and Linhares, ES state. The variables collected and analyzed annually were: failure of plant, plant health, breaking, forking, stem form, diameter at breast height, total height and volumetric average annual increment. The volume was estimated using models developed for each species. It was verified expressive faults planting onlyCariniana legalis ,Zeyheria tuberculosaandGoniorrhachis   marginata . Only Vitex sp. presented phytosanitary restrictions.Spondias venulosa ,Goniorrhachis   marginataandKielmeyera albopunctatastood out with the highest rates of breakage.Goniorrhachis   marginata, Manilkara   bella and Basiloxylon brasiliensisstood out with the lowest levels of bifurcation.Manilkara   bella, Cariniana   legalis e Zeyheria   tuberculosastood out as the form of a straight stem form.Spondias venulosapresented an expressive and superior to other species growth. More studies are needed to support the economic reforestation of that species, emphasis on studies of genetic improvement, silvicultural techniques, techniques of sawing and timber technology that points out the skills to use.
