dc.descriptionABSTRACT – We aimed to evaluate the technical efficiency of mini-cuttings technique on vegetative propagationof Paulownia fortunei (Seem.) Hemsl. var. Mikado, as well as the possible existence of anatomical barriersto its rooting. Therefore, plants originated from cuttings formed the mini-stumps and, consequently the clonalmini-garden, which was conducted in semi-hydroponic system. We evaluated the survival of mini-stumps andsprouts production for five successive collects, the percentage of mini-cuttings rooting and their anatomicaldescription. The mini-cuttings were prepared with about 6 to 8 cm in length and two leaves reduced by about50% in the upper third, being remained an area of, approximately 78 cm² (10 cm diameter). The mini-cuttingswere placed in tubes of 53 cm³, with substrate formed with fine vermiculite and carbonized rice hulls (1:1v/v) and rooted in acclimatized greenhouse. After 30 days we evaluated the percentage of rooted mini-cuttings,radicial vigor (number and length of roots / mini-cutting), callus formation, emission of new shoots and maintenanceof the original leaves. The mini-stumps showed 100% survival after five collects and an average productionof 76-114 mini-cuttings/m²/month and rooting ranged from 70 to 90%. Mini-cuttings technique is efficientin to propagate adult propagules of the species and there are not anatomical barriers preventing roots emission.
