ResumoThe purpose of this experiment was to study the phenological stages from pruning to harvest of the ‘Niagara Rosada’ grapevine grafted on different rootstocks grown on Cerrado conditions (Brazilian savanna) at the Goiás State, in the middle west of Brazil. The trial was carried out in Mineiros County, to evaluate phenological stages of ‘Niagara Rosada’ grapevines grafted on three rootstocks (‘Ripária do Traviú, ‘IAC-766 - Campinas’ and ‘IAC-572 - Jales’ and cultivated on climate and soil conditions of Cerrado (Brazilian savanna). The results showed that the cycle (from pruning to harvest) of ‘Niagara Rosada’ had differences on number of days according to the rootstock: 109 days on ‘Ripária do Traviú’, 112 days on ‘IAC-766’, and 113 on ‘IAC-572’, and the thermal summation requirements to complete the phenological cycle of ‘Niágara Rosada’ were 1,167.4, 1,197.9 and 1,207.4 degree-days, respectively. It can be concluded that climate and soil of Cerrado provided cycle reduction of ‘Niagara Rosada’. Key words: Vitis vinifera, rootstock, phenologycal characterization, Brazilian savanna.
