Each phase in the minicutting process is essential for the success of the seedling production. The objective of this study was to assess the time for rooting in minicuttings of five Eucalyptus grandis hybrid clones and to adjust models that best express the behavior of the genetic materials during the rooting process. The minicutting rooting process was carried out in a acclimatized greenhouse and at three-day intervals, adventitious rooting was evaluated until the 24th day. By the analyses, it was possible to verify peculiarities in relation to the behavior of each clone during the rooting period and to conclude that the necessary time for the process differs among the genetic materials, allowing the identification of the best rooting point of minicuttings.
