Popis: The objective of this work was to evaluate the influence of shade level on the production of T. myrmecophila seedlings. After 30 days of seedling transplantation, the seedlings were submitted to the following treatments: 100% light (full sun), 75% light and 50% light. The statistical design was completely randomized with 5 replicates of 10 seedlings each per treatment. The data were analyzed by repeated measures in time, in 5 measurements, performed every 30 days (150 days of evaluation). The analyzed variables were shoot height and diameter. The environment with 75% luminosity was the one that contributed most to the growth in height of the seedlings, having presented higher mean values over time, in the 5th month (34.94 cm). The most pronounced effect for growth in diameter was verified in the 5th month of evaluation, where the highest average was obtained in the environment with 50% of shading (4.61 mm). The T. myrmecophila seedlings were influenced by the shading levels used. From the results evaluated, treatments with 75% and 50% of solar radiation provided superior growth for dendrometric variables height and diameter, respectively. Therefore, we recommend environments with 75% and 50% of solar radiation for the production of T. Myrmecophila seedlings.
