【 摘 要 】

This work veriflied the influence of planting spacing on the initial growth of six forest species, at the age of 22 months, in plantations of forest recomposition in the Guandu River Basin. The experiment was installed in the SFE - thermoelectric power plants Barbosa Lima Sobrinho, located in the City of Seropédica-RJ. Forty eight tree species were planted, using the spacings, 1.0 x 1.0, 1.5 x 1.5, 2.0 and 2.0 x 3.0 x 2.0 m, which are the study treatments. At 22 months after planting, it was evaluated the growth in height, diameter at ground level (DNS) and area of the canopy for the species, Anadenanthera macrocarpa Benth. Brenan (angico vermelho), Schinus terebinthifolius Raddi (aroeira pimenteira), Schizolobium parahyba Blake (guapuruvu) Chorisia speciosa St. Hill (paineira), Cordia sp. (babosa branca) and Inga marginata (ingá). It was found that the studied species behaved in a different way in the differents spacing of planting, and that the planting density significantly influenced on the initial growth of all the species. In general, in wider planting spacings, the plants had higher growth.
