The objective of this study was determinate the time of permanence of an Eucalyptus clone, in acclimatized greenhouse for rhizogenesis of minicuttings. The experiment was realized in acclimatized greenhouse during 24 days, and for 6 days in full sun condition. The adventitial roothing was evaluated in 6 repetition constituted of 11 minicuttings in regular time intervals of three-days. The criteria used to determine the optimum time for rooting of propagules was the intercept of the daily current increase curve (DCI) and daily average increase (DAI). By the analyses of the results was verified that at 18 days after of the minicuttings were planted the seedlings already had conditions to be relocated to another stage of the production process, be it acclimation in shade or full sun.
