Seedlings growth of Peltophorum dubium (Canafístula) and Clitoria fairchildiana (Sombreiro) were evaluated in different shade degrees, which are usually used in the reforestation of Rio de Janeiro's slopes. Seeds were collected from several trees and sown directly in plastic bags. Shade levels tested were: 0% (full sun), 30%, 50% and 75%. The experiment started 1 month after sowing. Height was evaluated after 30, 60, 90, 120 and 150 days of the installation. Root dry weight was analysed 150 days after the installation. Studied species have shown different behaviours in relation to the analysed parameters. It is recommended to the immediate plantation to growth sombreiro’s seedlings under shade of 30% and canafístula, under full sun, 30% or 75% of shade. If you would like to stock the seedlings you should keep sombreiro’s seedlings under full sun and canafístula’s seedlings under 50% of shade. Both species may be planted under full sun, 30%, 50% and 75% of shade, and they are indicated for the beginning of a reforestation or for the enrichment of an area.
