The aim of this work was to evaluate the dynamics of microcutting and minicutting techniques during rooting process, by monitoring root emergence and development in microcuttings and minicuttings of four Eucalyptus grandis clones. Microcuttings were obtained from in vitro rejuvenated plant-derived sprouts, whereas minicuttings from rooted sprouts derived from plants propagated through conventional cutting technique. The results suggest the greater rooting ability of the microcuttings as compared to the minicuttings, evidenced by the number of roots/cuttings, total root/cutting length, largest root/cutting length, mean length of roots/cutting and dry weight of roots.
