Abstract

DANNER, Moeses Andrigo et al. Taking roots of 'jabuticaba' fruit tree (Plinia trunciflora) by air layering technique. Rev. Bras. Frutic. [online]. 2006, vol.28, n.3, pp.530-532. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452006000300043.

The aim of this work was to test the air layering technique in the production of cuttings of 'jabuticaba' fruit tree using different concentrations of Indolbutiric Acid - IBA (0, 4000 and 6000mg.L-1), in different times and in two places: August, October, December and May of 2004/2005 in Vitorino, Paraná, Brazil; and August, September, October and November of 2004 in Chopinzinho, Paraná, Brazil. The percentage of rooting was evaluated, through the observation of externally visible roots to the substrate, a hundred and eighty days after the execution of air layering technique. Based on these results it is possible conclude that: the air layering technique was an efficient assexuated method to propagate "Jabuticaba" fruit trees (Plinia sp.); the concentration of 4000 mg.L-1 was efficient in the induction rooting, exception when the air layering technique is executed in December, dismissing use of IBA.
