The present study aimed to evaluate the influence of different patterns of mini-cuttigs on rooting and production of hybrid Eucalyptus grandis Hill x E. urophylla S. T. Black hybrid in summer and winter. Experiments with five clones and 12 different patterns of mini-cuttings were conducted in two seasons (summer and winter). The survival and rooting were evaluated ate the output greenhouse and output of the shade and in full sun, survival, height, diameter, the dry weight of shoot and root. The results indicated that the maintenance of leaves is important for rooting mini-cuttings of Eucalyptus grandis Hill x E. urophylla S. T. Black hybrids, and the basal leaves had higher values of rooting. Seedlings produced in summer, using cuttings of 10 cm in size, had higher growth's methodology leaves no reduction procedure proved suitable for seedling production in both seasons.
