Aiming to stud the capacity of vegetative propagation of Dovyalis sp. by layering method, this work was developed. It was used branches of 50 cm length, which received the following treatments: 0; 1,000; 3,000; 5,000 and 7,000 mg/kg of indolbutiric acid (IBA) diluted in lanolina, in two periods: autumn and spring. In autumn the layering was distributed in superior and inferior part of the canopy and north and south sides of the plant. In spring, due to few branches it was just considered treatments with IBA. The autumn period demonstrated the highest percentage of root formation (93.93 %) and number of roots (10.26 %), and the root formation do not depend on branch position on the plant. The highest length of root was obtained in spring.
