Abstract

SASSO, Simone Aparecida Zolet; CITADIN, Idemir  and  DANNER, Moeses andrigo. Cutting propagation of jabuticaba tree. Rev. Bras. Frutic. [online]. 2010, vol.32, n.2, pp.577-583.  Epub June 11, 2010. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452010005000054.

The objective of this work was to test the efficiency of cutting technique for the propagation of jabuticaba tree (Plinia cauliflora). The rooting potential of wood cutting was tested, using four concentrations of Indolbutiric Acid - IBA (0, 2000 , 4000 and 6000 mg L-1) and two procedures (cross section and cutting girdling). Also the rooting potential of softwood terminal cuttings was tested, using five concentrations of IBA (0, 2000, 4000, 6000 and 8000 mg L-1) in two periods of implantation (October and December 2007). The rooting percentage was evaluated 180 days after the experiment started. It was observed that rooting of wood cutting is dependent on the application of IBA, so the biggest rooting percentage (50%) was obtained in biggest concentration of IBA (6000 mg L-1) associated with cross section. For the softwood terminal cuttings, the rooting percentage was smaller (maximum of 10%), however there is the potential of rooting, and, changes of technique which must be tested for maximization.
