Abstract

ABSTRACT The experiments were carried out to evaluate the effect of medium acidic and aluminum, as well as determine the most suitable concentration of indolebutyric acid (IBA) for rooting cuttings of different genotypes of Camellia sinensis L (tea plant). Such, stems were collected from mother plants in Pariquera-Açu, São Paulo state, Brazil, in winter 2012 and prepared semi-hardwood cuttings, with one bud and one leaf, which were kept in a nursery with 70% of shading. Irrigation substrate was taken with water and solutions containing phosphoric acid and aluminum sulfate at pH 5.5, 4.5; 3,5. In the first experiment, the experimental design was completely randomized in a factorial scheme 3x7, three genotypes (F 15, IAC 259 and Comum) and seven different conditions of rooting (vermiculite at pH 6.5, acidified with phosphoric acid or aluminum sulfate vermiculite at pH 3.5, 4.5 and 5.5). In the second experiment, the treatment that promoted the highest rooting in the first experiment (vermiculite acidified with aluminum sulfate at pH 3.5) was combined with treatment with IBA The experimental design was completely randomized in a factorial scheme 3x6, three genotypes and six concentrations of IBA (0, 2.000, 4.000, 6.000, 8.000 and 10.000 mg L-1). Vermiculite acidified with aluminum sulphate to pH 3.5, combined application of 10.000 mg L-1 IBA for 30 seconds was the most appropriate treatment for cutting propagation of genotypes F15, IAC 259 and Comum. Vermiculite acidified with aluminum sulfate at pH 3.5, combined treatment with 10,000 mg L-1 IBA for 30 seconds, was the most suitable conditions for the rooting of cuttings Camellia sinensis L.
