Abstract

In the rhizogenic process, the immersion time of the base of the cuttings to be propagated in plant regulators depends on the concentration of the solutions, the cultivar to be used and the type of cutting required. Therefore, this research work has as objective to investigate which immersion time, in solution with indolebutyric acid promotes a greater rooting in herbaceous cuttings of guava cultivar Século XXI. The experiment was distributed in the completely randomized design, being defined as treatments the immersion times (5, 10, 15 and 20 seconds) of the base of the cuttings in the solution of indolebutyric acid - IBA at the concentration of 2000 mg L-1, with three replicates and 10 cuttings per plot. In relation the variable dry mass of the aerial part, this presents a favorable response to the different immersion times in indolebutyric acid. Diverging of the variables cuttings rooted, live without root, number of roots, root length, callus, sprout, leaf retention and mortality which were not influenced by the different immersion times of the base of the cuttings in the plant regulator. Concluding that the different times of immersion of the base of the cuttings do not influence in the rhizogenic process of herbaceous cuttings of guava cultivar Século XXI. For the variable dry mass of aerial part, the immersion time of 5 seconds in the concentration of 2000 mg L-1 in AIB, present the better results when compared to the other concentrations.
