This work evaluated the effect of the pre-germination in the initial growth of Bauhinia forficata seeds in different substrates. The seeds were submitted to the pre-germination in humidified germitest paper with solution of cloranfenicol 1 mL.L-1 of distilled water. After, the paper was taken to the germination chamber at 25 ºC during eight days. After this period, the pregerminated seeds and intact seeds (witness) had been taken in local nursery and sown in different substrata: organic composition (50%) + subsoil land (50%); sand (25%) + subsoil earth (75%) and subsoil erth (100%). The diameter of collects, height of the plants, leaf number, green mass of the aerial part and of root and dry mass of the aerial part and of root, 60 and 120 days after the sowing, were evaluated. After 60 days, no statistical difference was noted between tested substrate. However, the treatments of the seeds demonstrated significant difference and the pre-germinated seeds presented higher values in all of the evaluated parameters. After 120 days, the organic composition presented better result, except for de collect diameter, leaf number and dry mass of the root. For the treatment of the seeds, the pre-germination presented better results for all evaluated parameters, except for the leaf number. The results pointed out that the composed organic substratum and subsoil land are the best procedure for the production of the B. forficata. Moreover, the pre-germination provided more vigorous plantules and seedlings with higher weight and growth in comparison to the control.
