Abstract: This study evaluated the potential for development in the greenhouse, cuttings of the hybrid of Eucalyptus grandis x Eucalyptus camaldulensis in Sinop - Mato Grosso and generated equations to estimate the percentage of rooting parameters. Were measured: the percentage of cuttings with some degree of modification, the percentage of cuttings in the percentage of cuttings with roots larger than 10 cm in length. Also measured was the neck diameter, height and leaf area index. The heights and leaf area showed lower development within the greenhouse. The rooting potential is based on curve speed of rooting and was found 12 days after staking. The identification of the optimal point of withdrawal of the shoots of the greenhouse through the intercept curves daily current increase curve (DCI) e daily average increase (DAI), being 19 days after staking. The company derives the stakes with 24 days underdoing the potential of the species and structures used.Keywords: Eucalyptus, greenhouse management and rooting
