This experiment was carnea out at Ducke reserve, Amazonas, Brazil in order to detect the influence of shading on the production of D. excelsa seedlings. The shading intensities (30%, 50% and 70%) were obtained by using black plastic screening. The evaluation of height, coll r diameter, shoot and rood dry weight of D. excelsa seedlings was performed after 30, 60 e 90 days in the nursery. The following results were obtained: a) with regard to period, seedlings with higher height were removed with 90 days; for the other paramenters abalyzed, no significant differences were found; b) seedlings with higher height were produced to 30% and 50% shading; collar diameter and seeding height decreased significantly with 70% shading, c) higher above ground dry weight biomass of seedlings were obtained when lower shading levels were used (30% and 50%).
