The selection of the most appropriate grape rootstock regarding the production purposes has a positive effect on quality of the grape, the must and the wine: it may produce higher vintage quantity and may increase the vintage quality. Field experiment was set up at the model farm of University of Debrecen on sand soil. 12 different grape rootstocks were compared (’Aramon x Riparia 143B M et de G’, ’Vitis Berlandieri’, ’Berlandieri x Riparia Szilágyi 157 Pécs’, ’Berlandieri x Riparia S.O.4’,’Berlandieri x Riparia T5C Eger’, ’Berlandieri x Riparia T.G. 5.A.5.’,’Berlandieri x Riparia T.8.B.’,’Berlandieri x Riparia T.K. 5.BB’,’Berlandieri x Riparia K.125AA’,’Riparia Sauvage’, ’Riparia Selecta’, ’Riparia Tomentosa’). ‘Cserszegi fszeres’ scion was grafted into the above rootstocks. The aim of our research was to determine how the B, Cu, Fe, Mn and Zn contents of the berry skins change in case of the different grape rootstocks. In 2011 we obtained valuable differences in the boron, copper, iron, manganese and zinc concentrations of skins of ‘Cserszegi fszeres’ grafted into different rootstocks. The concentrations of B, Cu, Fe, Mn and Zn changed between 18.0-32.0 mg kg-1, between 1.27-4.77 mg kg-1, between 11.5-45.0 mg kg-1, between 3.78-14.0 mg kg-1, and between 2.14- 8.53 mg kg-1, respectively. On the basis of our results the ‘Riparia Sauvage’ could be an advantageous rootstock, as the largest boron, iron and manganese concentrations were found in its skin. Advantageous rootstocks could be the ’Berlandieri x Riparia Szilágyi 157 Pécs’ because of the largest measured copper content and the ‘Vitis Berlandieri’ due to the largest measured zinc content. These results support that the selection of the rootstocks influence the B, Cu, Fe, Mn and Zn contents of the grape berry.
