It was evaluated the development of "Baru" seedlings (DipteryxalataVog.) in pots under three levels of shading and four textural classes, from March to October 2010, in Campo Grande-MS. Treatments consisted of 0%, 30% and 50% levels of shade and sandy, medium clay and heavy clay soil. The experimental design was randomized blocks in split plots with repeated measures. It was used three replicates of ten plants per plot. The shading levels corresponded to the treatments and the different textural classes to the subplot. Plant height, leaf number and stem diameter were evaluated 15 days after emergence (DAE) to 195 DAE. Survival rate, leaf area and dry mass of the leaf, the stem and the roots were also estimated at 195 DAE. Higher values were observed in height and leaf area under shading condition. Plant height was 32.09 cm and 31.21 cm plant-1, leaf area was 639.24 cm ² and 580.49 cm² for 50% and 30% shade levels respectively. In clay soil the values were higher in most traits followed by soil with loamy soil. The highest yield of dry mass of leaf was in the clayey soil with an average of 7.28 g plant-1.The percentage of seedling survival in sandy soil was lower than in the others. There was an interaction between levels of shading and texture classes of soil on dry mass of the roots which was higher (1.43 g kg-1 soil) on the loamy soil at 50% shading. "Baru" seedlings reached measurements of height and diameter suitable for all levels of shading and textural classes.
