Abstract

The present work aimed to evaluate the influence of different concentrations of indolbutiric acid (0, 2000, 4000, 6000 and 8000 mg L^-1) in the rooting of cuttings and vigor of the produced seedlings of Sapium glandulatum. The results obtained with relationship to the rooting indicated the best results for the dose of 6000 mg L^-1of AIB, with average of 52%, demonstrating this to be the most suitable concentration for the production of seedlings of this species. It was concluded that rooting cuttings technique of Sapium glandulatum is technically viable and could be used in the production of seedlings, thus overcoming problems of shortage of seeds and low germination rate. Also, it could be an alternative for production of seedlings all the year.
