The objective of the present study was to evaluate the influence of the serial minicutting technique on the rooting vigor of seedlings of four Eucalyptus grandis clones. Following seven minicutting subcultures, the minicuttings were rooted under greenhouse conditions (25 days), with acclimatization for 10 days in the shade and final seedling evaluation at 50 days old, under full light. In general, the serial subcultures promoted an increase in the number of roots and provided greater initial root vigor for clones with less rooting potential, suggesting a positive effect of the serial minicutting technique on Eucalyptus clones for these characteristics.
