The serial minicutting technique consists in the collection off shoots from minicuttings previously rooted and it has providing positive effects on the reinvigoration of some eucalyptus clones. This research aims to evaluate the survival and rooting of the serial minicuttings from guava tree cultivars Paluma, Pedro Sato and Cortibel 6. The experiments were carried out in a randomized block design (RBD) with four repetitions, being each plot composed of three minicuttings. Seventy-two days after the cutting, the minicuttings from Paluma, Pedro Sato and Cortibel 6 guava tree cultivars showed 100, 100 and 92% of survival and 100, 75 and 62.5% of rooting, respectively. The results have evidenced that serial minicutting allows the survival and rooting of Paluma, Pedro Sato e Cortibel 6 minicuttings similar to the minicutting technique, being suitable for the multiplication of these cultivars.
