Effect of indolbutiric acid and times of cutting on rooting of herbaceous cuttings of fig (Ficus carica L.) - DOI: 10.4025/actasciagron.v31i1.6635

Abstract

This work had as objective to verify the effect of six concentrations of indolbutiric acid (IBA) in the rooting of herbaceous cuttings of fig (Ficus carica L.) under intermittent mist irrigation, at three different times. The assays were installed in May, September and January, where in each time the used experimental design was entirely randomized, with six concentrations of IBA (0, 500, 1,000; 1,500;, 2,000; 2,500 and 3,000 mg L^-1). The cuttings were collected at the Experimental Station of Unesp, located in the municipal district of Selvíria, Mato Grosso do Sul, Brazil, standardized at 10 cm long and two leaves. After the cutting preparation, they were immersed in Metiltiofan solution for one minute, and later immersed in IBA solutions for 10 minutes. Next, they were planted in flower boxes containing vermiculite. They were transported to a greenhouse, with 50% light reduction, with overhead irrigation of the intermittent mist type. The analyzed variables were: percentage of surviving cutting and taken root, number of roots and mass, maximum length of the root system and dry matter of the root. In the conditions in which the study work was conducted, it can be concluded that: the herbaceous propagation of fig is viable; there was an effect of IBA in May only, where the best concentration was 1,000 mg L^-1; the best times for herbaceous cutting of fig are in September and January, without the use of IBA, in which the best results were obtained for the percentage of rooted cuttings.
