Conteúdo: 	Bertholletia excelsa is a tree species economically important in Peru, Brazil, and Bolivia. In the Amazon, seedlings production of tree species is a bottleneck faced by many producers. Although the great economic relevance of B. excelsa, there are few transplantation methods or techniques that brings more seedlings quality for the species. Thus, the objective of this work was to assess the influence of pruning or shoot cut and the different recipient volumes on the seedlings quality of B. excelsa. Thirty days after germination seedlings were transplanted to 115- and 345-cm³ small plastic tubes filled with standard substrate and arranged in forest nursery under 60% shading. The experiment set up was fully randomized in a 2 x 2 factorial (with and without shoot cut x 115-cm3 and 345-cm3 little tubes) in four treatments and four repetitions of 10 seedlings each. ANOVA followed by the Tukey test were applied on the means (p < 0.05). Pruning of B. excelsa seedlings when transplanted did not influence in the seedlings? quality, even though some variables such as stem collar diameter and root length presented positive responses. B. excelsa seedlings produced in 115-cm3 small tubes presented growth restrictions while seedlings produced in 345-cm3 small tubes had higher Dickson quality index at 165 days.
