We evaluated the productivity and survival of Poincianella pyramidalis, Senegalia bahiensis and Enterolobium contortisiliquum ministumps in different tubes sizes. Completely randomized design (CRD), containing three treatments (tubes of 50, 180, 280 cm³) were carried out with Poicianella pyramidalis, Senegalia bahiensis and Enterolobium contortisiliquum as experiments 1, 2 and 3, respectively. We analyzed ministumps survival after successive collections, number of sprouts per ministump every 15 days and number of minicuttings per ministump after successive collections. When data presented normality variance analysis and Tukey´s test were carried out at 5% probability. It was observed high survival of the ministumps for the three species after successive collections of minicuttings, indicating potential to use this technique. It was also noticed that small volume containers can affect sprout productivity negatively and in consequence the number of minicuttings per ministumps.
