The experiment was conducted in two commercial vineyards located in the counties of S??o Joaquim (28??14?S, 49??58?W, 1.300 m) and Urubici (27??56′S, 49??34′W e 1.150m), evaluation the phenology, summation of GDD and maturation of Merlot grafted onto 1103P, 3309C and 101-14 Mgt. We conclude that The phenology of Merlot grapevine grafted onto different rootstocks showed variation in the occurrence of phenological stages. The average advance in the occurrence of veraison of Merlot grafted on 101-14 Mgt was related to higher accumulation of thermal time, and decreased total acidity, suggesting an advance in the maturation of the berries when compared to 1103P.  a101-14 Mgt  a1103 P  aFenologia  aMerlot  aUva1 aBEM, B.
