Abstract: Rootstocks affect the vigor, yield and fruit quality besides the physiology and alter the resistance of the scion to abiotic and biotic stress factors. In viticulture, different rootstocks affect the same scion also in different ways. This study was conducted in five years old vineyard in Manisa conditions. Leaf samples of Cabarnet Souvignon, Merlot and Syrah cultivars grafted on 110 R (Vitis berlandieri x Vitis rupestris) and 1103 P (Vitis berlandieri x Vitis rupestris) were taken during veraison. Proline, carbohydrate, color (CIE L*, a*, b*) and chlorophyll (SPAD) contends of the samples were analyzed. The effects of the rootstocks on scion were compared. The obtained data were interpreted according to statistical analysis and Duncan Multiple Comparison Test was used to state the differences. Statistical differences in all parameters were noted when all rootstocks and scion combinations evaluated together. When rootstocks effects on scion analyzed, 1103 P were found statistically significant in all parameters except carbohydrate values where 110 R were found insignificant in proline, a* and L* values. As a result rootstocks were found effective on evaluated physiological parameters and scions have different response on the same rootstock
