The rooting of hardwood cuttings in three pear rootstocks: 'Taiwan Nashi-C'(Pyrus calleryana Decaisne), 'D'água' (Pyrus communis L) and 'Manshu Mamenashi' (Pyrus betulaefolia Bunge) without growth regulators. Wood cuttings with 20 cm long and 3 - 4 buds were treated or not with a basal cut and manteined in intermittent mist condition for 60 days. The 'Taiwan Nashi-C' and 'D'água' presented 53,8 and 51,8 % of rooting, respectively, in treated and untreated cuttings. The 'Manshu Mamenashi' cuttings showed excessive bud bursting and almost no rooting. The basal cut was efficient on 'D'água' rootstock rooting.
