Resumo: | There is little knowledge about the vegetative propagation of Ilex   paraguariensis, mainly in relation to the minicutting technique and  rooting environmental aspects. This  study aimed to evaluate the initial  rooting environment in relation to the survival, shoot vigor and  minicuttings  rooting of this species. The experiment was conducted in  a completely randomized design, under a factorial  arrange (3x2), with  three clones (A7, A21 and A35) and two rooting environments (simple greenhouse - without  control of temperature and humidity; and automatized greenhouse - with automatized control). The minicutting   survival in the exit of greenhouses and in the exit of shadow house  was not influenced by the tested  environments, with 51.8 % to 71.9 %  of survival variation. The A7 and A21 clones did not present  significative  difference in relation to rooting, with averages of 49.1 %  and 46.4 %, respectively. However, the A35 clone showed the best   development (62.5 % of rooting) when it was cultivated under  automatized greenhouse condition. The  automatized greenhouse  favored not only the characteristics leaf and shoot numbers, but also  the shoot length. The  minicutting technique for I. paraguariensis may  be considered viable in both evaluated rooting environments, which   presented similar results.
