Abstract

Rootstocks are well known as the most efficient way to limit phylloxera. However, they can be useful in order to improve grape quality. This study aimed to compare the content of polyphenol compounds in vine fruits of the cultivar ‘Regent’ grafted on ‘Couderc 161-49’, ‘Sori’, ‘Kober 125AA’, ‘Börner’ or ‘Kober 5BB’ rootstocks, or planted on own-roots. Grape samples were collected in three consecutive seasons (2013-2015) at a research station of the West Pomeranian University of Technology Szczecin in Poland. Thirty-three phenolic compounds were determined in the juice of examined samples using ultra-pressure liquid chromatography with photodiode array and mass spectrometry (UPLC-PDA/MS) method. A significant influence of rootstock on the content of polyphenols in grapes has been proven. The highest content of polyphenols was shown in fruits from a scion grafted on ‘Sori’ and ‘Kober 125AA’ rootstocks (675 and 643 mg · 100 g-1 FW, respectively). ‘Börner’ and ‘Kober 5BB’ rootstocks did not have a significant influence on the creation of polyphenol compounds in comparison to own-root plants. In addition, the use of the ‘Börner’ rootstock resulted in fruits with an especially low content of phenolic acids.
