Enraizamento adventício de estacas apicais de figueira e desenvolvimento inicial das plantas no campo

Abstract

Althoug the vegetative propagation of the fig tree has being practiced a long time ago, studies aiming at defining new methods are important, specially using apical cuttings and growth regulators. The present work had the objective to verify the behavior of fig plants obtained from rooting using sucrose diluted in solutions of IBA, through fast immersion. Woody and flat cuttings of the apical portion standardized with 20 cm of length were immerged in solution with and without sucrose at 2%, diluted in IBA (0, 1000, 2000, 3000 and 4000 mg.L-1) for 5 seconds. After the immersions the cuttings were placed in recipients measuring 26 x 14 cm, filled with a substrate composed by soil and sand (2:1 v/v) and transferred to a greenhouse with humidity and temperature control. After 60 days, the roots and aerial part were evaluated. Part of the plants was transferred to the field in recipients constituted of rigid plastic with 5 liters of capacity filled with substrate composed by soil and cow manure (3:1 v/v). After 120 days it was verified that cuttings treated or not with sucrose or IBA in the rooting process have similar behaviors in the field, and the treatment with IBA is only necessary to increase the rooting percentage.
