Enraizamento de estacas caulinares e radiculares de Rubus fruticosus tratadas com AIB

The objective of the present work was to evaluate the rizogenic potential for stems and root cuttings of Rubus fruticosus treated with indolbutyric acid. Roots and stems cuttings of this specie were collected in March, and had their basal portions treated with different concentrations of indolbutyric acid (IBA) (1000, 2000, 3000 and 4000 mg L-1) for 10 seconds. The control treatment used only water. The stem cuttings were planted with 2/3 of their length in the vertical position and the root cuttings were totally covered in the horizontal position, using vermiculite as substrate, in screenhouse with 50% of shade. After 60 days, the stem cuttings presented better results for seedling formation, without IBA.
