The objective of this study was to evaluate the influence of serial minicutting technique on the production capacity, vigor and survival of Eucalyptus grandis ministumps in successive minicutting collections. The miniclonal garden was located in an environment covered by transparent plastic, under a hydroponic system. The survival of ministumps was superior to 96% after the seven collections were conducted for all the clones and subcultures. Regarding ministump productivity and vigor, variations were observed among clones and collections and the serial minicutting technique did not provide significant effects, overall.
