Abstract

SASSO, Simone Aparecida Zolet; CITADIN, Idemir  and  DANNER, Moeses Andrigo. Propagation of jabuticaba tree for grafting and air layering techniques. Rev. Bras. Frutic. [online]. 2010, vol.32, n.2, pp.571-576.  Epub June 11, 2010. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452010005000055.

The objective of this work was to test the efficiency of grafting and air layering propagation techniques for jabuticaba tree. Was tested compatibility of grafting of three species of jabuticaba tree (Plinia cauliflora, P. trunciflora and P. jaboticaba) on rootstocks of P. cauliflora, and two periods (May and August). The percentage of grafting, number and size of shoots, was evaluated 90 days after the experiment started. Air layering was made in P. cauliflora using two diameters of branches (1.0-1.5 cm and 2.0-2.5 cm) and two widths of girdling (1.5 cm and 3.0 cm). It was evaluated the rooting percentage, number and length of roots, 180 days after the experiment started. Both grafting and the air layering are recommended for jabuticaba tree propagation, because these techniques provide high percentage of nursery plant formation, up to 72.9% and 87.5%, respectively. There is grafting development of the three species grafted onto P. cauliflora rootstocks. The utilization of grafts collected from plants in fructification should be avoided, because they reduce the percentage of grafting development. In air layering, branches with diameter of 2.0-2.5 cm provide higher percentage of rooting, number and size of roots, than branches with smaller diameter (1.0 to 1.5 cm).
