Abstract

Guaco is a climbing vine of Asteraceae family that is popularly used for the treatment of respiratory problems. The objective of this work was to evaluate the influence of dipping in water, stem cutting position and the use of growth regulators on the rooting of stem cuttings. The experiments were carried out in greenhouse in October 1995. The treatments of the first experiment were applied to cuttings from the different positions of the stem (apical, medium and basal). Each set of three cuttings was then dipped in water for one, twelve and twenty four hours, respectively. The influence of dipping in water and growth regulators was evaluated in another experiment. The average stem size was 1.5 to 2.0 m which was divided in three parts (apical, medium and basal). Stem cuttings maintained two half leaves and were 15 cm in size. This vegetative material was submitted to dipping treatments and planted in pots of washed sand. After 40 days, the root weight, stem weight and rooting percentage were evaluated. The treatment with one hour of dipping increased the rooting percentage averages, except for the basal stem cuttings. The rooting percentage varied between 62.5 to 100%, according to the treatment. The best averages were verified on treatments of dipping in water (95%) and in indole-3-propionic solution (93%). The indole-3-butyric acid reduced the rooting percentage average (81%).
